FASTENER INSTALLATION

TECHNIQUE

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 engage-
ment. 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. Exces-
sive voids between purlins sometimes damages drill points and two self drillers might be necessary to
complete the operation. It is sometimes advantageous 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 sufficient torque to seat the washer - do not overdrive the fastener.
