NOTE:
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 fas-
teners periodically.
Shear bolts are designed to fail under predetermined loads. Always replace shear bolts
with identical property class fasteners.
Fasteners should be replaced with the same or higher property class. If higher property
class fasteners are used, these should only be tightened to strength of original.
Make sure fastener threads are clean and that the threads are properly started. This will
prevent them from cross threading or galling when tightened.
Tighten plastic insert or crimped type steel locknuts to approximately 50% of dry torque
indicated on chart. Apply torque to the nut – not the bolt head. Tighten toothed or serrated
type locknuts to full torque value.
LUBRICATED means coated with lubricant. DRY means plain or zinc plated without any
type of lubricant.
