Metric Torque Values Chart
DO NOT use these values if a different torque value or
tightening procedure is given for 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 property
Fasteners should be replaced with the same or higher
property class. If higher property class fasteners are
used, these should only be tightened to the strength of
“Lubricated means coated with a lubricant such
as engine oil, or fasteners with phosphate and oil
coatings. “Dry” means plain or zinc plated without
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, no to the bolt head. Tighten
toothed or serrated-type lock nuts to the full torque
