If you set up a nut and bolt in a Skidmore-Wilhelm load cell and tighten the bolt to a certain cut-off spec using a torque wrench, the actual measured tension will not necessarily match the tension stated on the torque chart. 0000051046 00000 n zip. )Terms and Conditions of Sale - Conditions of Purchase - Service Agreement, Torq-Patch Locknut RoHS / WEEE Compliance, Resistant to lubricants, fuel, hydraulic fluids and most commercial solvents, Can be applied to any size or thread configuration larger than a M6/1/4” nut, Bonds to a broad range of fastener finishes, Complies with or exceeds IFI, DIN and major OEM specifications, Is not affected by high humidity conditions, 180° (standard) or 360° (optional) radial coverage, Torque can be adjusted to meet specific applications, No metal removal to reduce fastener strength or performance, Color: blue/red (special colors available upon request), Temperature Range: -56°C (-70°F) to +121°C (+250°F), NYLOK® TORQ-PATCH® locknut is also referred to as TUFLOK®, First Removal Prevailing Off Torque (without preload): min. Grade C Grade B Grade G Using the proper torque helps ensure that the wheel assembly is securely installed. Grade 2 calculations only cover fasteners 1⁄4"-3⁄4" in diameter up to 6" long; for longer fasteners the torque is reduced significantly. A nyloc nut, also referred to as a nylon-insert lock nut, polymer-insert lock nut, or elastic stop nut, is a kind of locknut with a nylon collar that increases friction on the screw thread. The primary is torque. Now install nyloc, and tighten until the bolt is the same lenght as with the plain nut, thats as close as you can get with nyloc's. The amount of torque required to run the nut down (friction drag torque) should be measured and added to the amount of torque specified for the fastener. 0000027112 00000 n Seems to be two lines of thought on using nylock fasteners..:blink: "Nylock adds a secondary retention to the nut. Nylok® Torq-Patch® Locknut is a self-locking element comprised of nylon permanently bonded into the threads of a nut. The outside diameter of the ring is constrained, so the inside diameter must allow this deformation without overfilling the mating thread, or the ring can be pushed out of the nut. Prevailing torque of the lock nut should be determined by testing an actual nut and fastener and that number should be added to the desired torque to arrive at a torque spec. ** Torque values for 1/4" and 5/16" sizes are in inch lb. A nut with a nylon insert to prevent backing off. This metal to metal contact results in a positive resistance to vibration and loosening.

Metric Bolt Torque Chart. 0000056491 00000 n Nyloc Nut - Nylon Insert Lock Nuts A nylon insert lock nut, also referred to as a nyloc nut, polymer-insert lock nut, or nylon insert (elastic) stop nut, is a common type of locknut comprised of a hex nut with a fixed nylon-filled collar at its back end. It is available in stainless steel, carbon steel, and alloy steel to bear more wear and tear while also making it more corrosion resistant. Using nylock nuts allows you to use it repeatedly without damaging the threads of screws, but it comes at the cost of damaging the nylon present in the nut. If, however, we take our original torque of 10.5 and add the 2 that the Nylock requires and set our torque wrench to 12.5, our clamp load is 2,511 pounds. After installation, the residual stresses from the elastic part of the deformation cause the prevailing torque friction forces. When nuts are submitted to a laboratory for testing, samples are tested in a room temperature environment, with special external threads, and installed with hand tools or other slow speed tools. While the nut is suitable to be reused multiple times, be wary of the damage caused to the nyloc threads. These nuts are created to a standard of DIN 6926. 0000026674 00000 n 0000026217 00000 n Unbrako hex nuts, nylock nuts, hex weld nuts, coupling nuts & serrated flange nuts - Metric & Inch.
