testing capabilities Creep Test A Creep Test measures how a material deforms over time when subjected to a constant load and elevated temperature. Unlike standard tensile or hardness tests, which provide immediate property data, creep testing evaluates a material’s long-term behavior under sustained stress . This test is especially important for fasteners used in high-temperature environments, where even small amounts of time-dependent deformation can lead to joint loosening, dimensional instability, or failure. How the Test is Performed Specimen Preparation – A fastener or representative sample is prepared and mounted in a creep testing machine. Constant Load Application – A steady load, typically a percentage of the material’s tensile strength, is applied. Elevated Temperature Exposure – The specimen is heated to a defined service-relevant temperature and maintained throughout the test. Monitoring Deformation – Elongation or strain is continuously measured over an extended period (ranging from hours to months). Data Collection – The rate of deformation and time to failure (if it occurs) are recorded and analyzed. Why It is Performed Creep testing is performed to predict how materials and fasteners will behave under long-term service conditions , particularly in environments involving high heat and sustained loads. This ensures that components will not gradually deform or fail in ways that could compromise equipment safety and reliability. Evaluates time-dependent deformation at elevated temperatures Predicts service life under continuous stress Verifies material and heat-treatment suitability Prevents dimensional changes or joint failures in critical applications Application to Engineered Fasteners Engineered fasteners often operate in turbomachinery, aerospace engines, nuclear reactors, and energy systems , where they are exposed to both constant loads and extreme temperatures.

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 .

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.
