MANUFACTURING PROCESSES Laser Marking Laser marking is a precise and non-contact process used to create permanent markings on engineered fasteners and components. It is often employed for identification, traceability, and branding purposes. The Laser Marking Process: 1. Laser Source: A laser beam, generated by a fiber, CO2, or Nd:YAG laser, is directed onto the surface of the material to create the marking. The type of laser used depends on the material and the desired marking effect. 2. Material Interaction: The high-energy laser interacts with the surface of the fastener or component, causing localized changes without damaging the structural integrity. These changes can include: Color change (annealing): Controlled oxidation that changes the surface color. Engraving: Ablating material to create a recess in the surface. Foaming: Raising material slightly to create a raised marking. Carbonization: Darkening certain areas for contrast. 3. Marking Design: Patterns, alphanumeric codes, logos, or 2D barcodes are programmed into the laser system and precisely applied to the surface. 4. Non-Contact Process: The laser operates without physically touching the material, ensuring no mechanical stress or deformation of the component. Why Use Laser Marking for Engineered Fasteners? Enhanced Quality Control: Ensures every fastener can be traced back to its origin for quality assurance. Customization: Enables detailed and consistent branding or functional markings. Minimal Downtime: Fast and efficient marking suitable for automated production lines. Limitations Initial Cost: Laser marking equipment can be expensive to purchase and set up. Material Sensitivity: Some materials require careful parameter adjustments to avoid unwanted effects. Marking Depth: For deep engravings, multiple passes or specialized lasers may be needed. Advantages of Laser Marking: Durability: Markings are permanent, resistant to wear, corrosion, and environmental conditions. Precision: Creates high-resolution, detailed markings without damaging the material. Versatility: Suitable for a wide range of materials, including stainless steel, titanium, aluminum, and nickel alloys. Efficiency: Fast marking speeds make it ideal for high-volume production. Non-Intrusive: No physical contact with the workpiece eliminates risks of deformation or mechanical damage. Eco-Friendly: No inks, chemicals, or consumables are required, reducing waste and environmental impact. Applications in Engineered Fasteners: Laser marking is essential for fasteners and components where traceability, quality assurance, or branding is critical. Applications include: Traceability: Marking unique identifiers such as serial numbers, part numbers, or batch codes on fasteners for quality control and tracking. Compliance: Adding certifications or standards (e.g., ISO, ASME) to fasteners used in industries like aerospace, nuclear, and medical. Branding: Permanently engraving company logos or trademarks on custom fasteners to enhance brand recognition. Size and Specification Information: Marking dimensions, materials, or thread specifications directly onto the component. Functional Markings: Adding indicators, scales, or alignment marks to components for assembly or operational purposes.

testing capabilities Cleanliness Test A Cleanliness Test is a quality inspection method used to determine the level of contaminants—such as oils, grease, machining residues, metal shavings, or foreign particles—present on a manufactured component. For engineered fasteners and precision-machined parts, even trace contamination can affect performance, assembly, or long-term reliability, making cleanliness verification a critical part of the quality process. How the Test is Performed Sample Preparation – The fastener or machined component is handled under controlled conditions to prevent outside contamination. Extraction of Contaminants – Solvents, ultrasonic agitation, or pressurized fluids are used to dislodge surface and embedded particles from the part. Collection & Filtration – Dislodged contaminants are collected and passed through a fine filter. Analysis – The particles and residues are measured by weight, size, or count using gravimetric, microscopic, or spectrographic methods. Evaluation Against Standards – Results are compared to customer or industry-defined cleanliness requirements. Why It is Performed Cleanliness Testing is performed to ensure that fasteners and machined components meet strict contamination-free requirements that protect assembly quality, performance, and durability. Prevents assembly issues such as galling, seizing, or torque misapplication Reduces risk of corrosion or premature wear caused by foreign particles Ensures compatibility with lubricants, coatings, and protective finishes Meets customer requirements for industries where contamination can cause system failure, such as aerospace, oil & gas, and defense Application to Engineered Fasteners Engineered fasteners often operate in demanding environments where any contamination can compromise safety and performance.

testing capabilities Slow Strain Tensile Test A Slow Strain Tensile (SST) Test, sometimes called a Constant Extension Rate Test (CERT), is a specialized variation of tensile testing that applies strain at a very slow, controlled rate. This method is designed to evaluate a material’s susceptibility to stress corrosion cracking (SCC) or other time-dependent failure mechanisms that occur under simultaneous mechanical stress and corrosive environments. For critical fasteners, the SST Test provides essential insight into long-term reliability in demanding applications. How the Test is Performed Specimen Preparation – A fastener or machined sample is prepared and placed in a tensile testing machine. Controlled Strain Application – Instead of applying a load rapidly, strain is applied at a very slow and constant rate. Environmental Conditioning – The specimen may be exposed to a corrosive medium (such as a salt solution, hydrogen sulfide, or other environment relevant to service conditions). Monitoring and Measurement – Load, elongation, and time to failure are carefully recorded. Result Analysis – The data is analyzed to determine susceptibility to stress corrosion cracking or other strain-related failures. Why It is Performed The SST Test is performed to ensure that fasteners can maintain their integrity when subjected to simultaneous mechanical stress and corrosive environments . Standard tensile tests may not reveal susceptibility to stress corrosion cracking, which can lead to sudden, catastrophic failures. Detects vulnerability to stress corrosion cracking (SCC) Evaluates long-term durability under slow, sustained loading Confirms material and heat treatment effectiveness in corrosive environments Ensures safe, reliable performance of fasteners in mission-critical applications Application to Engineered Fasteners Engineered fasteners are often used in aerospace, oil & gas, marine, nuclear, and defense applications where they face both sustained loads and harsh environments. Slow Strain Tensile Testing helps TSP Manufacturing ensure that these fasteners: Resist cracking and embrittlement under real-world service conditions Maintain strength and ductility in corrosive environments Provide assurance of long-term performance where standard tensile testing is not sufficient Prevent catastrophic failures that could compromise equipment safety and reliability Standards & Compliance At TSP Manufacturing, Slow Strain Tensile Testing is conducted in compliance with ASTM, NACE, ISO, and customer-specific standards . All testing equipment is calibrated, and procedures are performed by qualified personnel to ensure accuracy, repeatability, and traceability.

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.
