Silicon bronze wood screws - square drive head

Silicon Bronze Wood Screws - Square-Drive Head 12-Gauge

(1 review) Write a Review


High-quality 12-gauge silicon bronze wood screws in a variety of lengths.  These silicon bronze screws have a #3 square-drive head and are ideal for use as boat building screws.

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.

We also recommend silicon bronze screws (or silicon bronze machine screws for high-load situations) for fastening our bronze deck hardware.

You are welcome to buy individual screws or benefit from quantity discounts if you buy more (your discount will be calculated automatically when you enter the quantity above).

    I live in Hobart and it normally takes quite a few days to get something delivered. With this order I received the items next day. Fantastic response
