Torque Values and Friction Coefficient - All Metal Self Locking Nuts - Where Torque tightening equipment is used, account should be taken of the additional torque required to overcome the resistance of the prevailing torque locking nut. Nylon insert lock nuts that experience field issues, most often, … This metal to metal contact results in a positive resistance to vibration and loosening. You can use your torque wrench to measure Nylock nut torque and then add this value to the bolt's required torque. They are a one piece all metal prevailing torque type hex lock nut having a conical top with chamfered corners. 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. )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. 0000056491 00000 n

Hexagon locking nuts with a nylon locking ring inserted. Clamp loads for Grade C lock nuts equal 75% of the bolt proof loads specified for SAE J-429 Grade 8, and ASTM A-354 Grade BD bolts. These nuts can withstand extreme amounts of torque and therefore, can be used in high strength and industrial applications. Nylok® Blue Nylon Torq-Patch® Tuflok® is a self-locking element comprised of nylon permanently bonded onto the threads of a fastener. If you want the iPart, you can pull it from the cbliss site. Example: bolt and nut are both phosphated; required torque = torque recommended x 0.75. h�b```g``�����p�#��XX80t�``�s I�!X�����Zo��� >�`ZFG�����Ҁ����!��w�@�����~�f�BI�^֙"�b�����}XǶ�z�C�W���,��d�. A Nyloc (nylon insert) Nut is a torque prevailing nut which uses a plastic/nylon insert located towards the top of the nut, reducing its inner diameter, which then deforms over the mating thread. The nylon collar insert is placed at the end of the nut, with an inner diameter (ID) slightly smaller than the major diameter of the screw. The nut is locked by means of three radial brass locking pins arranged at the same angle as the thread flanks. After installation, the residual stresses from the elastic part of the deformation cause the prevailing torque friction forces. A nut that stays tight. Unbrako hex nuts, nylock nuts, hex weld nuts, coupling nuts & serrated flange nuts - Metric & Inch. 0000027630 00000 n
Cap A nut with a domed top over the end of the fastener. When the Nylok® Torq-Patch® Locknut is engaged, it creates a wedge between the nut and mating part compressing the nylon and creating metal to metal contact opposite the patch.

A193 B7 uses 75% of the yield strength. Nylon Insert Jam Lock A nylock nut with a reduced height. These nuts are created to a standard of DIN 6926. 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. 0000014050 00000 n
zip. Page 1 of 2 - Tie Rod Nylock Nut Torque - posted in Problems, Questions and Technical: When torquing a nylock nut, is it correct to determine the friction torque required to overcome the self locking feature of the nut and then add that figure to the required torque? Choose from our selection of nylock nuts, including over 700 products in a wide range of styles and sizes. The nut is now tightened till the torque value is reached. I would suggest a nylock nut for something like this because its clean & simple and can still be removed. December 1st, 2013 Nylock Nut, Inch UNC STP.stl. All other torque values are in foot lb.

Nylok® Blue Nylon Torq-Patch® Tuflok® Prevailing Torque Locking Element. Flange Nyloc (nylon insert) Nuts are torque prevailing nuts which use plastic/nylon inserts that are located towards the top of the nut – which reduce its inner diameter – therefore deforming the insert over the mating thread and capturing the bolt or screw and providing a locking feature. 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. stl.
