The nominal torque values listed are for general use only with the assumed
wrenching accuracy of 20%, such as a manual torque wrench.
DO NOT use these values if a different torque value or tightening procedure is
given for a specific application.
For lock nuts, for stainless steel fasteners, or for nuts on U-bolts, see the
tightening instructions for the specific application.
Replace fasteners with the same or higher property class. If
higher property class fasteners are used, tighten these to the
strength of the original.
•
Make sure that fastener threads are clean.
•
Apply a thin coat of Hy-Gard™ or equivalent oil under the head and on the threads of the fastener, as shown in the following image.
•
Be conservative with the amount of oil to reduce the potential for hydraulic lockup in blind holes due to excessive oil.
•
Properly start thread engagement.
