5.4 MANDREL
WARNING:
While a small amount of wear and marking will naturally occur through the normal
and correct use of mandrels, they must be regularly examined for excessive wear and marking,
with particular attention to the head diameter, the tail jaw gripping area of the shank or heavy
pitting of the shank and any mandrel distortion. Mandrels that fail during use could forcibly
exit the tool. It is the customer‘s responsibility to ensure that mandrels are replaced before any
excessive levels or wear and always before the maximum recommended number of placings.
Contact your STANLEY Engineered Fastening representative who will let you know what that
fi gure is by measuring the broach load of your application with a calibrated test tool.
