Different Types of Metal Roof Screws
BDN Fasteners offer a full range of Australian AS3566 Standard self-drilling and self-tapping screws for steel to steel and steel to timber applications in various coating options to cope with different environments.
Our sharp pointed metal roof screws to wood screws, TIMBER-Tite™ are designed for fixing roof sheeting to timber. The longer versions such as the T17CG1265C3N or T17CG1250C3N are designed for crest fixing and shorter versions such as the T17H1020C3N are designed for valley fixing.
POLYXPAND™ & POLY-FAST™ fasteners features a cutting washer to create a much-required thermal expansion hole on plastic profiled roofing panels, which is then securely fastened onto the purlin support underneath in one-go. A nominal 11mm diameter thermal expansion hole is created during the process. The cutting washer also functions as stopper when mated with serrated knurls on the shank, preventing screw over-run or over-drive, and squashing of the raised profile. Fool proof design for both beginners and professionals.
With 100% Made in Taiwan being an inherent part of the BDN Fasteners DNA, our collated screws are no different – everything from the screws to the collating of strips are all done in our facilities. BDN Collated screws undergo stringent, in-house quality control tests during and after manufacturing, minimizing any possibility of jamming during application.
