Amadas 9960 - Torque Values; Appendix C Torque Values

Appendix C - Torque Values
This section lists the torque valves for
metric and unified bolt and cap screws.
Please note the following:
• Torque values listed are for general
purpose only. Do NOT use these
values if a different torque value or
tightening procedure is given for a
specific application.
• Check tightness of fasteners
periodically.
• Shear bolts are designed to fail under
predetermined loads. Always replace
shear bolts with the identical property
class.
• Fasteners should be replaced with the
same or higher property class. If a
higher property class of fasteners is
used, tighten these fasteners only to the
strength of the original.
• Make sure fastener threads are clean
and that you properly start thread
engagement. This will prevent fasteners
from failing when they are tightened.
• Tighten plastic insert or crimped steel-
type lock nuts to approximately 50
percent of the dry torque shown in the
chart. Apply to the nut, not to the bolt
head.
• Tighten toothed or serrated-type lock
nuts to the full torque value.
• In the torque value charts, “lubricated”
refers to items coated with a lubricant
such as engine oil, or fasteners with
phosphate and oil coatings. “Dry” refers
to plain or zinc plated items without any
lubrication.
