FASTENER INSTALLATION
USING SCREWS:
For fastening with screws, it is best to use a painted or plated screw, Type A or driller tip with a flat rubber washer. The
correct screw gun is also important to the proper installation of self-drilling or self-tapping screws. A tool with the appropriate
speed and torque setting (as recommended by the fastener manufacturer) will help prevent fastener thread strip-out and
possible damage to the panel or its coating.Typically 40 screws should be used per square for 2' wide panels and 80 screws
should be used per square for 3' wide panels.
SCREW ATTACHMENT
CORRECT
Sealing material slightly
visible at edge of washer.
Assembly is water tight.
TOO LOOSE
Sealing material is not
visible; not enough
compression to seal.
TOO TIGHT
Washer is deformed;
sealing material pressed
beyond fastener edge.
SEATING THE WASHER - Apply sufficient torque to seat the washer - do not overdrive the fastener.
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.
