Silicon Bronze Screw 14g x 4″ Square Drive Flat Head

Silicon Bronze Screw – Square Drive Flat Head 14g x 4″ (100mm)

Square drive 14-gauge silicon bronze wood screws.  These silicon bronze screws have a countersunk (CSK) head and are ideal for use as boat building screws, decking screws and other applications.

The square-drive head makes fastening with your electric screw-driver or cordless drill very quick and simple. The driver bit will remain locked in and will not slip, unlike other head types.

Even buried in the wooden structure of a boat, silicon bronze screws will not corrode – unlike stainless steel screws which will corrode when shielded from oxygen and unable to build a protective oxide layer.

Head Diameter: 11.6mm

Shaft Diameter: 4.9mm
