Thread Size
M5 X 0.8
M6 X 1.0
M8 X 1.25
M10 X 1.5
M12 X 1.75

Note: Reduce torque values listed in the table above
by 25% for lubricated fasteners. Lubricated
fasteners are defined as threads coated with
a lubricant such as oil, graphite, or thread
sealant such as Loctite
Note: Torque values may have to be reduced when
installing fasteners into threaded aluminum
or brass. The specific torque value should be
determined based on the fastener size, the
aluminum or base material strength, length of
thread engagement, etc.
