*Lub
means coated with a lubricant such as engine oil, or fasteners with phospate or oil coatings. "Dry"
means plain or zinc plated without any lubrication.
DO NOT use these values if a different torque value or tightening procedure is given for a specific applica-
tion. Torque values listed are for general use only. Check tightness of fasteners periodically.
Make sure fastener threads are clean and that you properly start thread engagement. This will prevent them
from failing when tightening. 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.
Tighten plastic insert or crimped steel-type lock nuts to approximately 50 percent of the dry torque shown
inthe chart, applied to the nut, not the bolt head.
