Silicon Bronze Screw 16g x 3″ Square Drive Flat Head

Silicon Bronze Screw – Square Drive Flat Head 16g x 3″ (75mm)

Square drive 16-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: 12.9mm

Shaft Diameter: 5.7mm
