Metric Bolt and Cap Screw Torque Values (Continued)
DO NOT use these values if a different torque value or tightening procedure is given for a specific application. Torque values listed are for general use only and include a DO NOT use air powered wrenches.
Shear bolts are designed to fail under predetermined loads. Always replace shear bolts with identical grade.
Fasteners should be replaced with the same grade. Make sure fasteners threads are clean and that you properly start thread engagement. This will prevent them from failing when tightening.
When bolt and nut combination fasteners are used, torque values should be applied to the NUT instead of the bolt head.
Tighten toothed or serrated-type lock nuts to the full torque value.
a"Lubricated" means coated with a lubricant such as engine oil, or fasteners with phosphate and oil coatings. "Dry" means plain or zinc plated without any lubrication.
