THE SCREW FOR ALL STEEL TO STEEL JOBS - Box of 100
Trunk-Tite is a self-drilling screw which has been developed for all steel to steel jobs such as:
- Cable trunking
- Earth tags and many more
Featuring a square drive, stick fit, it allows the user to fix in awkward, hard to reach places. Perfect for tricky applications and saving time – no more spanners, nut or bolts.
The unique thread provides an ultra-strong fix because it goes right to the head - it won't work loose.
The sharp drill point starts immediately delivering an extra fast insertion and the flat pan head reduces the risk of overdriving.
