28 Mar Batten Zips®
Batten Zips are part of the Buildex Type 17’s Self Drilling Screws range:
1. The thread on a Type 17 is parallel for constant clamp load.
2. The drill point is sharp pointed and drills the timber to a pulp consistency.
3. The special end slot forms a thread cutting action into the timber. The timber it cuts becomes pulp like sawdust, which is distributed evenly into the open cell structure in the timber. This becomes stabilised by the frictional heat generated while cutting, eliminating timber expansion and minimising the splitting of timber.
For fastening thin metal battens to timber trusses and steel purlins up to 1.5mm thick.
