FASTENER INSTALLATION
To prevent wobbling - Make sure fastener head is completely engaged in the socket. If the head does not go all the way
in the socket - tap the magnet deeper into the socket to allow full head engagement. Metal chips will build up from drilling
and should be removed from time to time.
Protect drill point - Push only hard enough on the screw gun to engage clutch. This prevents excess friction and burn out
of the drill point. Correct pressure will allow screw to drill and tap without binding.
Drilling through sheet and insulation - Ease up on pressure when drilling through insulation to avoid striking the purlin or
girt with the point - apply more pressure after drill point contacts purlin or girt.
Drilling through purlin overlaps - Drilling through lapped purlins requires extra care. Excessive voids between purlins
sometimes damages drill points and two self-drillers might be necessary to complete the operation. It is sometimes advanta-
geous to predrill.
Recommended Tool Type - Use depth locating nose or adjustable clutch on screw gun to prevent overdrilling and strip out.
Do not use impact tools or runners.
Seating the washer - Apply sucient torque to seat the washer - do not overdrive the fastener.
