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 at 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 sufcient 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.
