3mm<br />
When a pin is driven into steel, it displaces the steel laterally 360° around<br />
the shank of the fastener. Since steel is an elastic material, it 6mm presses back<br />
against the shank of the fastener to hold it in place.<br />
• Some fasteners feature a knurled shank which allows the steel to<br />
form a key lock into the grooves to provide higher load capacities.<br />
WARNING! Fasteners should not be used in areas that have been welded or cut with a torch as these<br />
procedures may have caused local hardening of the steel. Over driving of the fastener should be avoided<br />
as the rebound created may reduce the load capacity or cause damage 3mm<br />

Load Capacity in Steel<br />

The load capacity of Fixture a powder actuated fastener 3mm<br />

on the following factors:<br />

Pin Length Selection<br />
For permanent applications<br />
in steel, first determine 13mm the<br />
thickness of the fixture to<br />
be fastened. To this, add<br />
the thickness of the steel<br />
base material plus a<br />
minimum of 6mm to allow<br />
for point penetration.<br />
Do not select a fastener length<br />
longer than that required for<br />
38mm<br />
the application. An excessively<br />
long shank can burnish or<br />
polish the hole, resulting in a<br />
reduction in load capacity.<br />
Edge Distance<br />
For installations 38mm in steel,<br />
13mm is the recommended<br />
minimum edge distance.<br />
Smaller edge distances may<br />
cause the base material<br />
to bend or break.<br />
Spacing<br />
The recommended minimum<br />
distance between fastenings<br />
is 38mm centre to centre for<br />
installations in steel.<br />
