Installation Guidelines

A standard screwgun with a depth sensitive nosepiece should be used to install teks. For optimal fastener performance, thru screwgun should be a minimum of 4 amps and have a RPM range of 0-2000.
Adjust the screwgun nose piece to properly seat the fastener.
Worn or damaged bit tip should be replaced.
The fastener is fully seated when the head is flush with the work surface.
Overdriving may result in torsional failure of the fastener or stripout of the substrate.
The fastener must penetrate beyond the metal structure a   minimum of 3 pitches of thread.
All # 10 diameter ''Winged'' parts must be driven into a minimum of 16  GA steel thickness.
All 1/4 and #12  diameter ''Winged'' parts must be driven into a minimum of 1/8  steel in order to break the wings consistently.
