Your T4 tools can be used for a wide range
of fastening needs in a variety of base
materials. Reading and following these
important fastening guidelines will help you
get the best results from your
tool and fasteners, as well as help you
perform these fastening operations
safely and effectively.
T4 fastenings are permanent
fastenings so attempting to remove
a fastener from concrete or steel
may result in a serious injury.
When fastening into concrete, always
maintain a minimum spacing of 3”
between fastenings and 3” from any
free edge. Concrete thickness should
be at least three times the intended
penetration depth into the concrete.
Driving fasteners too close to an
edge or too close to each other
can cause the concrete edge to
fail or fasteners to fly free.
Take care to observe a 3” edge distance
to avoid cracking the block and over
penetration of the fastener to avoid a
loss of holding value. Fastenings may
also be made into the horizontal joint
but not into the vertical joint.
Your T4 tools can be used for fastening on
the flat surfaces of structural steel. When
fastening into steel, always maintain a
minimum spacing of 1-1/2” between
fastenings and 1/2” from any edge.
