Select Options:

Features & Applications

Hexagon head screws with a self-drilling point are for fastening to structural steel. They have a fine thread and TEK 5 point for steel from 4.0mm to 12.5mm, with a three-stage zinc-ceramic coating. Listed variants include screw sizes from 5.5 x 32mm upward and corresponding thread lengths. Select the screw length to suit the steel thickness being fixed.

Installation

1. Screws should be installed using a Tek screwdriver or cordless

drill with adequate power and a drilling speed of between 1500

– 2500 rpm. (IMPORTANT - Impact screwdrivers will damage

the threads and must not be used)

2. Use a 5/16" socket to install the screw perpendicularly into the

steel maintaining steady pressure without forcing the tool.

3. Stop inserting the screw as soon as the flange makes contact

with the surface. Overtightening the screw is liable to damage

the thread particularly in thinner steel.
