Additional Metric Cap Screw Torque Values
CAUTION: Use only metric tools on metric
hardware. Other tools may not fit properly.
They may slip and cause injury.
Check tightness of cap screws periodically. Torque values
listed are for general use only. Do not use these values if
a different torque value or tightening procedure is listed
for a specific application.
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 fastener threads are clean and you properly
start thread engagement. This will prevent them from
failing when tightening.
Tighten cap screws having lock nuts to approximately 50
percent of amount shown in chart.
