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. Check tightness of fasteners periodically.
Shear bolts are designed to fail under predetermined loads. Always replace shear bolts with identical grade.
Fasteners should be replaced with the same or higher grade. If higher grade fasteners are used, these should only be tightened to the strength of the original. Make sure fasteners threads are clean and that you properly start thread engagement. This will prevent them from failing when tightening.
Tighten plastic insert or crimped steel-type lock nuts to approximately 50 percent of the dry torque shown in the chart, applied to the nut, not to 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.
b Grade 2 applies for hex cap screws (not hex bolts) up to 152 mm (6-in) long. Grade 1 applies for hex cap screws over 152 mm (6-in) long, and for all other types of bolts and screws of any length.
