For ARP and other performance bolts check their specs with their specific type of lube as it will make a difference. It is readily apparent that if the torque intended for a When we torque a bolt where does it go? 50% of the torque applied is used up in overcoming the nut bearing friction 40% of the torque applied is used to dissipate the thread friction 10% of the torque is used to raise the load “generate preload” Variations in the coefficient of friction have a huge effect upon the preload Bolt tightening torque Use a torque wrench, well-lubricated fasteners, and hardened flat washers to ensure correct initial loading. The above Table is applicable only for ASTM A320 Grade L7, A193 Grade B7 and A193 Grade B16 Stud Bolts. Lubed means cleaned, dry bolts, lubricated with standard medium viscosity machine oil. Bolt Torque Calculation Example Lockwashers and cap bolts are then applied and tightened to complete the assembly to the proper tightening torque for the specific cap bolts. Lubricated bolt torque? Yes a big difference since you not counting the friction of a dry bolt thread as final torque. Over-torque can cause wear or premature failure of a bolt or nut from overstress on threaded areas REQUIRED PRACTICES NOTE: Make sure that the torque applied is for the size of the bolt shank not the wrench size. 15 Zinc Plated 0. 4kN to 5. 737562 0. This video shows the relationship between a required torque value and the applied thread/nut lubrication of a given bolt load Class 10. Driveshaft coupling nut (bell gear): 180 foot-pounds is the maximum and probably 150 is OK. There are two key pieces of information with each torque specification: the sequential order for tightening the set of bolts and the amount to tighten the bolts at each tightening step. Fasteners should be replaced with the same or higher property class. coatings. January. Sep 03, 2013 · Torquing preload in a lubricated bolt The tension preload obtained by torquing a 7/8 in. Torque values are based on clean, dry threads. 8 32 M10 1. 5 8. 16; Note! – be aware that this is a rough calculation – in addition the accuracy of a torque wrench is normally no better than +-25%. Why do bolt torque charts frequently vary with their torque values? As an example, for a certain size bolt, one chart may say to use 45 ft-lbs (61Nm), while another, for the same conditions, will say to use 55 ft-lbs (75Nm). That simply defines the maximum torque for the bolt itself without regard to the hole. This source offers torque, but no lube explanation. 2 which is • Use a torque wrench and well lubricated fasteners with flat washers to ensure correct initial loading. 085: u=0. Dry: Torque – FT LBS.
