INSTALLATION IN STEEL
The following guidelines are based on the installation of a fastener in ASTM A 36 structural steel with
the point fully penetrating the steel member. Recommended steel material thickness ranges from a minimum
of 1/8" to a maximum of 3/8". For use in higher strength structural steel, applications where the point does
not penetrate the steel member, or a thickness of steel greater than 3/8", job site performance tests are
recommended.
BASE MATERIAL THICKNESS
Steel base materials should be a minimum of 1/8" in thickness.
EDGE DISTANCE
For installations in A 36 steel, 1/2" is the recommended minimum edge distance.
SPACING
The recommended minimum distance between fastenings is 1-1/2" center to center
for installations in ASTM A 36 steel.
FASTENER LENGTH SELECTION IN STEEL
For permanent applications when using pins in steel, first determine the thickness of
the fixture to be fastened. To this, add the thickness of the steel base material plus a
minimum of 1/4" to allow for proper point penetration. This will be the minimum fastener shank length
required. Do not select a fastener length longer than that required for the application. An excessively long
shank can burnish or polish the hole created in the steel resulting in a reduction in load capacity.
For removable applications with threaded studs, the shank length required is equal to the thickness of the
steel base material plus a minimum of 1/4" to allow for proper point penetration. This will be the minimum fas-
tener shank length required. Do not select a shank length longer than that required for the application. An
excessively long shank can burnish or polish the hole created in the steel resulting in a reduction in load capaci-
ty. To determine the minimum threaded length, add the thickness of the fixture and the nut / washer thickness.
The nut and washer thickness is equal to the nominal thread diameter.
Do not over tighten threaded studs, the maximum tightening torque is listed in the table below. Use of a
nut setter is recommended to reduce the possibility of over tightening the fasteners. For critical applications,
perform a job site test.
Tool Operation
CAUTION: — Be sure to read and understand all of the safety precautions and training in
this manual before attempting to operate the tool. (Check to be sure the tool is not loaded,
the piston moves freely within the barrel, and no foreign objects or fasteners are in the
barrel.) Perform the daily function test before using the tool.
OPERATION
1. Always point the tool in a safe direction away from bystanders and the operator.
Slide the barrel forward. This can be done by snapping your wrist. The barrel should
be pulled fully forward to reset the piston for the next fastening. Loss of power may
result from an improperly positioned piston.
2. Always load the fastener before inserting powder load to prevent injury to the operator or bystanders in
the event of an accidental discharge. Place the fastener, point out, into the end of the
nose piece until the fluted tip fits inside. Do not use excessive force when inserting the
1/8"
1/2"
1-1/2"
