142 – SD HEX COARSE C3 12-14 X 30 (Pack 1000)

Hex head self-drilling screw for fastening through mild steel in steel sections, brackets, assemblies, and other metal items. The steel building industry can utilise this screw for a variety of purposes, and it also offers speedy installation features because the coarse thread instals a little bit faster than the fine thread version. They have very good pull-out strength because of their flanged hex head, which makes them perfect for both interior and exterior applications.
