testing capabilities Hardness Test A Hardness Test is a method of measuring a material’s resistance to deformation, indentation, or scratching. In manufacturing, hardness is closely tied to strength, wear resistance, and durability—critical properties for engineered fasteners and machined components. Various hardness scales (such as Rockwell, Brinell, or Vickers) are used depending on the material and application, providing precise data to ensure that parts meet design and performance requirements. How the Test is Performed Preparation – The fastener or component surface is cleaned to remove oils, coatings, or debris that could affect accuracy. Indenter Application – A controlled load is applied using a standardized indenter (such as a steel ball or diamond cone). Measurement – The depth or size of the indentation is measured, then compared against the appropriate hardness scale. Repeatability – Multiple tests can be performed on different areas of the component to confirm consistency. Documentation – Results are recorded to provide traceable data for quality assurance and compliance. Why It is Performed Hardness testing is performed to ensure that materials and finished fasteners possess the necessary strength and durability for demanding applications. A fastener that is too soft may deform or wear prematurely, while one that is too hard may become brittle and prone to cracking. By verifying hardness, TSP Manufacturing ensures that every part meets the performance balance required for safety and reliability. Confirms material strength and durability Verifies heat treatment and manufacturing processes Prevents premature wear, deformation, or failure in service Ensures consistency across production runs Application to Engineered Fasteners Engineered fasteners often operate under extreme loads, vibration, and environmental stress. Their hardness level directly affects how they perform over time, especially in industries such as aerospace, oil & gas, defense, and nuclear power. By applying hardness testing, TSP Manufacturing ensures: Correct material properties for strength and toughness Verification of heat-treated fasteners to confirm proper hardness levels Prevention of failure modes related to excessive softness or brittleness Confidence in product performance for safety-critical applications Standards & Compliance TSP Manufacturing performs hardness testing in accordance with ASTM, ISO, and customer-specific standards , using properly calibrated equipment and certified procedures. Our inspectors are trained to ensure accuracy, consistency, and traceability across all test results.

testing capabilities Wedge Tensile Testing A Wedge Tensile Test is a specialized variation of axial tensile testing designed specifically for threaded fasteners. By placing a hardened wedge under the head of a bolt during testing, additional bending stress is introduced. This simulates worst-case service conditions where the fastener may be misaligned or subjected to uneven loading. The test measures how well the fastener maintains tensile strength and integrity under this combined stress, making it a critical evaluation for safety-critical applications. How the Test is Performed Specimen Setup – A bolt or fastener is mounted in a tensile testing machine with a hardened wedge placed under its head. Load Application – A controlled axial tensile load is applied while the wedge creates an added bending stress. Monitoring – The fastener is pulled until failure or until a specified load requirement is reached. Observation – The type of failure (thread stripping, head fracture, shank break, etc.) is carefully documented. Result Analysis – Data is compared against design and industry standards to ensure compliance. Why It is Performed The wedge tensile test is performed to confirm that fasteners can withstand tensile and bending stresses simultaneously , ensuring reliability even in less-than-ideal installation or service conditions. Verifies overall tensile strength in a simulated worst-case scenario Detects weaknesses such as improper heat treatment or material flaws Ensures fasteners won’t fail unexpectedly due to misalignment or uneven load Provides added assurance of performance in critical, real-world applications Application to Engineered Fasteners Engineered fasteners used in industries such as aerospace, nuclear, oil & gas, and defense often face complex loading conditions. The wedge tensile test ensures that: Bolt heads and shanks can resist combined stresses without premature failure Thread integrity and material toughness meet customer and industry requirements Fasteners maintain reliability in high-stakes environments where safety is paramount Manufacturing processes and heat treatments are validated through destructive verification Standards & Compliance At TSP Manufacturing, wedge tensile testing is conducted in compliance with ASTM, ISO, and customer-driven specifications . All equipment is calibrated to industry requirements, and tests are performed by trained professionals to ensure accuracy, repeatability, and traceability. By strictly adhering to these standards, we provide our customers with confidence that our engineered fasteners can withstand even the most demanding service conditions.

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.
