testing capabilities Shear Test A Shear Test measures the ability of a material or fastener to resist forces that cause sliding failure along a plane parallel to the applied force. Unlike tensile testing, which pulls a component apart lengthwise, shear testing evaluates how well a fastener or component can withstand lateral or transverse forces. This property is critical for fasteners used in assemblies where loads are not purely axial but involve side-to-side stresses. How the Test is Performed Preparation – The fastener or specimen is mounted in a shear fixture designed for the test. Application of Force – A controlled load is applied by a testing machine, exerting force across the fastener’s cross-section or shear plane. Monitoring – The load is increased gradually until the fastener or specimen fails by shearing. Recording Results – The maximum load carried before failure is measured and converted into shear strength data. Analysis – Results are compared against design requirements and material specifications. Why It is Performed Shear testing ensures that fasteners can perform safely and reliably under service conditions where lateral or shear forces are present. It is particularly important for components in rotating machinery, aerospace structures, and heavy industrial applications, where failure in shear could compromise both equipment integrity and safety. Confirms shear strength meets design specifications Verifies material selection and heat-treatment processes Prevents premature failures in shear-critical applications Provides confidence in safety and performance under real-world conditions Application to Engineered Fasteners Engineered fasteners are frequently subjected to shear forces in bolted joints, couplings, and assemblies. For example, bolts used in turbomachinery, aerospace, or defense systems may experience both tensile and shear loads simultaneously.

testing capabilities Magnetic Particle Testing (MT) Magnetic Particle Testing (MT) is a non-destructive testing (NDT) method used to detect surface and near-surface discontinuities in ferromagnetic materials, such as steel and iron alloys. The process relies on magnetizing a component and then applying fine magnetic particles. These particles gather at areas of flux leakage caused by defects, making cracks, seams, laps, or inclusions visible to inspectors. How the Test is Performed Preparation – The fastener or machined component is cleaned to remove oil, grease, and debris. Magnetization – A magnetic field is applied to the part, either directly (passing current through the component) or indirectly (using a magnetic yoke or coil). Application of Magnetic Particles – Fine iron particles, either dry or suspended in liquid, are applied to the surface. Indication of Defects – If a discontinuity is present, it distorts the magnetic field, causing particles to cluster at the flaw. Inspection – Inspectors examine the part under visible light or ultraviolet light (if fluorescent particles are used) to identify and interpret defect indications. Post-Test Cleaning – The component is demagnetized and cleaned after inspection. Why It is Performed Magnetic Particle Testing is performed to ensure that fasteners and machined components are free from cracks or other surface-connected flaws that could compromise performance. Because many engineered fasteners are used in high-stress, safety-critical environments, even a small crack can propagate and lead to premature failure. MT is a fast, cost-effective, and highly sensitive method for detecting these flaws before components enter service. Detects surface and slightly subsurface cracks, seams, and laps Ensures quality and safety of ferromagnetic components Provides quick, reliable results to support efficient production and inspection cycles Application to Engineered Fasteners For engineered fasteners, surface and near-surface integrity is critical. Fasteners experience extreme loads, cyclic stresses, and environmental exposure in industries such as aerospace, oil & gas, and nuclear power. A small crack or seam undetected at the surface can become the origin of a failure under load. By applying Magnetic Particle Testing, TSP Manufacturing ensures: Fasteners are free of surface defects that threaten strength and reliability High-performance components meet industry and customer requirements Confidence in the long-term durability of fasteners used in safety-critical applications Standards & Compliance At TSP Manufacturing, Magnetic Particle Testing is carried out in strict accordance with ASTM, ASME, and customer-specific standards .

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.
