STEP 1:
A standard screw gun with a depth sensitive nosepiece should be used to install Teks. For optimal fastener performance, the screw gun should be a minimum of 4 amps and have an RPM range of 0-2500.

STEP 2:
Adjust the screw gun nosepiece to properly seat the fastener.

STEP 3:
New magnetic sockets must be correctly set before use. Remove chip build-up as needed.

STEP 4:
The fastener is fully seated when the head is flush with the work surface.

STEP 5:
Overdriving may result in torsional failure of the fastener or strip out of the substrate.

STEP 6:
The fastener must penetrate beyond the metal structure a minimum of 3 pitches of thread.
