MANUFACTURING PROCESSES Roll Threading Roll threading is a highly efficient and widely used method for producing threads on engineered fasteners and components. Unlike cut threading, roll threading forms threads by displacing material rather than removing it, which results in stronger threads with superior surface finish and fatigue resistance. The Roll Threading Process: 1. Preparation: A cylindrical blank (typically slightly smaller than the finished diameter of the thread) is prepared. The material must be ductile enough to deform without cracking, such as alloy steels, stainless steels, or titanium. 2. Thread Rolling Dies: Specialized thread rolling dies are used to create the thread profile. These dies can be: Flat Dies: Two flat, hardened dies squeeze the blank as it passes between them, forming the thread. Cylindrical Dies: Two or three cylindrical dies rotate around the blank to form threads. Planetary Dies: Multiple smaller dies rotate around the blank for high-speed production. 3. Thread Forming: The blank is fed into the dies, and high pressure is applied to displace the material into the thread shape. The process is typically performed at room temperature (cold forming), although warm or hot threading may be used for particularly hard materials. 4. Finishing: Threads are inspected for dimensional accuracy, pitch, and surface quality. Secondary processes, such as coating or heat treatment, may follow. Why Use Roll Threading for Fasteners? High Strength and Durability: Threads created by rolling are more resistant to fatigue and wear, making them ideal for critical applications. Efficiency for Mass Production: Roll threading can produce thousands of fasteners quickly with consistent quality. Cost Savings: Despite higher initial tooling costs, the reduced material waste and longer tool life make roll threading cost-effective in the long run. Advantages of Roll Threading: Stronger Threads: The material’s grain structure is compressed and aligned along the thread, improving strength and fatigue resistance. Improved Surface Finish: The forming process creates smooth, burr-free threads, reducing stress concentrations. Efficiency: Roll threading is faster and produces less waste compared to cut threading. Material Savings: No material is removed, resulting in near-net-shape threads. Longer Tool Life: Dies used in roll threading typically last longer than cutting tools. Applications in Engineered Fasteners: Roll threading is commonly used for fasteners that require strength, durability, and precision. Applications include: Bolts and Screws: High-strength threaded fasteners for aerospace, automotive, and industrial uses. Studs and Rods: Threaded rods used in construction, oil & gas, and machinery. Custom Fasteners: Non-standard or specialty threads for critical applications. Medical Components: Precision threads for implants or surgical instruments. Limitations Material Restrictions: Requires ductile materials that can deform under high pressure. High Initial Cost: Custom thread rolling dies can be expensive to manufacture. Limited Thread Profiles: Not all thread geometries can be rolled (e.g., very coarse threads or custom profiles). Preform Requirements: The blank must be pre-machined to specific dimensions before threading.

testing capabilities Charpy Impact Testing The Charpy Impact Test is a standardized method used to measure a material’s toughness , or its ability to absorb energy and resist fracture under sudden impact. The test evaluates how a material behaves when subjected to a high-strain-rate load, which is critical for engineered fasteners that may experience shock, vibration, or rapid loading during service. How the Test is Performed Specimen Preparation – A notched sample of the material or component is cut to standard dimensions and carefully prepared. Mounting – The specimen is positioned horizontally in a Charpy testing machine on two supports. Impact Loading – A pendulum hammer is released to strike the specimen at the notch, causing it to fracture. Energy Measurement – The machine measures the energy absorbed by the material during fracture, which reflects its impact toughness. Result Recording – The energy absorbed and fracture characteristics are documented for analysis. Why It is Performed Charpy Impact Testing is performed to ensure that materials and fasteners can withstand dynamic and sudden loads without brittle failure.

MANUFACTURING PROCESSES Heat Treatment: Stress Relieving Stress relieving is a heat treatment process designed to reduce internal stresses within engineered fasteners and components without significantly altering their mechanical properties or microstructure. These internal stresses typically arise from previous manufacturing processes such as forging, machining, welding, or cold working. Stress relieving ensures dimensional stability and reduces the risk of distortion or failure during subsequent use. The Stress Relieving Process: 1. Heating: The fastener or component is heated to a temperature below the material’s critical transformation point, typically ranging from 480°C to 650°C (900°F to 1200°F) for steel, depending on the alloy and application. 2. Soaking: The fastener is held at the target temperature for a sufficient time to allow the redistribution and relaxation of internal stresses. The duration depends on the component’s size and complexity, often ranging from 1 to 2 hours. 3. Cooling: After soaking, the fastener is cooled at a controlled rate, usually in still air, to prevent the reintroduction of stresses. Effects of Stress Relieving: Reduction of Residual Stresses: Internal stresses caused by prior manufacturing processes are reduced, improving dimensional stability and reducing the risk of cracking. Improved Performance: Stress-relieved fasteners are less prone to failure under cyclic or dynamic loading, enhancing fatigue resistance. Minimal Impact on Mechanical Properties: Stress relieving does not significantly change the hardness, strength, or microstructure of the material. Enhanced Machinability: Reduced stresses can make machining operations smoother and more predictable. Example of Stress Relieving in Fastener Manufacturing: 1. Material: Alloy steel bolt (e.g., 4140 steel). 2. Pre-Stress Relieving Process: The bolt undergoes cold heading and thread rolling, creating residual stresses. 3. Stress Relieving: The bolt is heated to 600°C (1112°F) and held for 2 hours. Air cooling is used to avoid rapid temperature changes. 4. Outcome: Internal stresses are reduced, ensuring the bolt maintains dimensional accuracy and resists fatigue during use. Benefits of Stress Relieving for Fasteners: Dimensional Stability: Reduces the risk of warping or distortion during further processing or use. Extended Service Life: Improved resistance to fatigue and stress-corrosion cracking enhances the durability of fasteners. Ease of Assembly: Stress-relieved fasteners have better thread alignment and fit, simplifying assembly operations. Enhanced Safety: Reduced internal stresses minimize the likelihood of sudden or catastrophic failure under load. Applications in Engineered Fasteners: Post-Machining: Fasteners that undergo significant material removal, such as bolts and studs, are stress-relieved to ensure dimensional accuracy. Cold-Worked Components: Stress relieving mitigates the stresses induced during cold heading, forming, or rolling operations. Welded Assemblies: Welded fastener assemblies, such as anchors or large bolts, benefit from stress relieving to improve their integrity and reliability. Critical Fasteners: Fasteners used in high-stress environments, such as aerospace or nuclear industries, require stress relieving for enhanced performance and safety. Challenges in Stress Relieving: Overheating: Heating the material above its critical transformation temperature can alter its microstructure, defeating the purpose of stress relieving. Oxidation: Without a controlled atmosphere, surface scaling or oxidation may occur, affecting the fastener’s appearance and performance. Residual Stress Redistribution: Uneven heating or cooling can reintroduce residual stresses, so process control is critical. Why Stress Relieving is Essential: Stress relieving ensures engineered fasteners and components perform reliably in demanding applications by reducing internal stresses while maintaining their inherent material properties. This makes it a vital step in manufacturing high-quality fasteners for industries requiring precision, strength, and safety.

MANUFACTURING PROCESSES Drilling Drilling is a fundamental machining process used in manufacturing engineered fasteners and components. It involves creating cylindrical holes in a workpiece using a rotating cutting tool called a drill bit. The Drilling Process: 1. Workpiece Preparation: The workpiece (made from materials like stainless steel, titanium, or nickel alloys) is securely clamped on a drilling machine or CNC machining center. The material’s properties dictate the type of drill bit and cutting parameters used. 2. Drill Bit Selection: The choice of drill bit depends on the required hole diameter, depth, and material. Common drill bits include twist drills, carbide drills, and coated drills for high-performance materials. 3. Rotating Tool Engagement: The drill bit rotates at high speeds while being fed into the workpiece, removing material to form a hole. Coolants or lubricants are often applied to reduce heat and improve tool life. 4. Hole Formation: The drilled hole can be further refined through secondary processes like reaming, boring, or tapping to achieve the desired finish and dimensions. 5. Precision Enhancement: CNC drilling machines ensure high accuracy and repeatability for complex hole patterns or tolerances. Enhancements with Drilling: Combination with Other Processes: Drilled holes can be threaded, counterbored, or countersunk in the same setup. Automation: CNC drilling increases speed and accuracy for high-volume runs. Tool Coatings: Advanced coatings like TiAlN or diamond reduce wear when drilling tough materials. Advantages of Drilling: Precision: CNC drilling ensures tight tolerances and high repeatability. Versatility: Can produce holes of various sizes and depths in a wide range of materials. Adaptability: Additional operations like tapping or boring can be integrated seamlessly. Cost-Effective: Drilling is efficient for high-volume production of standard and custom fasteners. Applications in Engineered Fasteners: Drilling is an essential step in producing fasteners and related components. Common applications include: Fastener Holes: Pilot Holes: Drilled to guide thread-cutting processes for screws and bolts. Clearance Holes: Allow screws or bolts to pass through without threading. Threaded Holes: Drilled holes that are later tapped to create internal threads. Complex Components: Drilled holes in flanges, bushings, and sleeves for mounting or alignment purposes. Countersinks and Counterbores: Used to create features that accommodate screw heads or washers. Custom Fasteners: Specialized holes for locking mechanisms, venting, or unique applications. Limitations Material Stress: Heat and force during drilling may affect material properties if not properly managed. Depth Restrictions: Very deep holes may require specialized equipment or techniques. Tool Wear: Drill bits can wear out quickly when working with hard materials like titanium or nickel alloys.

OUR PRODUCTS Nord-Lock Washers Home / Products / Standard Products / Nord-Lock / TSP Manufacturing + Nord-Lock TSP Manufacturing is proud to be Nord-Lock’s preferred distributor to the energy industry, providing advanced wedge-locking solutions for bolted joints subjected to extreme vibration and dynamic loads. TSP Manufacturing offers both prepackaged and custom quantities of Nord-Lock products, along with expert technical product support. PRODUCT INFORMATION Nord-Lock Washers Nord-Lock washers are easy and effective to use while ensuring structural security for applications exposed to vibration and dynamic loads. Installing the washers The pre-assembled washers are installed in pairs, cam face to cam face. Lubrication is recommended when possible. Tightening Tighten Nord-Lock washers with standard tools according to the guidelines. Tightening guidelines for other bolt grades are available through our technical representatives. Untightening Untightening Nord-Lock washers is as simple as tightening. Note that since the locking function is not based on increased friction, the untightening torque is generally lower than the tightening torque. Therefore it is not possible to measure offtorque as verification of locking function. Reusing Nord-Lock Nord-Lock washers can normally be reused. As with all fasteners, they should be inspected for wear before reassembly. Make sure that the washers are reinstalled correctly cam face to cam face. Nord-Lock recommends lubrication of fasteners before reuse in order to minimize changes in friction conditions. WHEN ONLY THE BEST WILL DO Washer Materials We Stock: Delta Protekt Stainless steel 254 SMO INCONEL/HASTELLOY C-276 INCONEL 718 To order contact our team today CONTACT DOWNLOAD PRODUCT CATALOG Nord-Lock Washer Product Information A pair of washers for maximum safety Nord-Lock bolt securing solutions consist of a pair of washers with cams facing each other and serrations gripping the mating surfaces. They use cam-geometry to effectively prevent the bolt from vibrating loose. Tension prevents bolts from rotating loose Think of the bolt as a spring. Turning the fastener during tightening stretches the bolt like a spring, creating the required clamp load to hold the parts together. Nord-Lock washers secure bolted joints by increasing this clamp load if the bolt tries to rotate loose. When the fastener is tightened, the cams lock and the serrations on the outer faces of the washers grip into both the fastener and the clamped part, creating clear impression marks in both. Clamping load has been created by the bolt, keeping the assembly locked in place. Because the cam angle ‘α’ is greater than the thread pitch ‘β’ a wedge-locking effect secures the fastener against rotational loosening, even under the most severe conditions. When the fastener is untightened, sliding will occur between the two washers. The upper washer is locked to the nut or bolt head by the serrations. The lower washer does not rotate as its serrations are locked into the surface being clamped. As the cams slide over each other, the clamping load from the bolt is first increased as the bolt stretches, before being released as the cams pass each other.
