SD Hex Coarse ZY 12-14 x 25

The SD Hex Coarse ZY 12-14 x 25 is a hex head self-drilling screw with a coarse thread, designed to drill and fix directly into timber or light steel without a pilot hole. It’s manufactured from zinc-plated steel, giving it a durable protective coating suited to general indoor and light outdoor use. The hex head allows fast, high-torque driving with a nut driver or socket — well suited to general fixing and light fabrication.
