Stainless Steel 410 timber screws Type 17

This decking screw is also called wood screw. Our stainless steel 410 screws do not oxidize and are extra hardened by a special heat treatment. As a result, the chance of them breaking is virtually nil. Pre-drilling in soft wood is a thing of the past thanks to the handy cutting tip. The cutting ribs of the chipboard screws make screwing in easier. The tension of the screw also decreases, so that it remains stronger. For hardwoods such as oak, Garapa hardwood, Kapur and Red Cedar, you always choose our stainless steel screws for Oak and Garapa hardwood. These are specially protected against extreme tannic acids.

Stainless steel A2 quality screws break regularly because the material is softer than galvanized chipboard screws. Due to the stainless steel 410 quality, the screws are just as strong as galvanized steel screws. Fix tightly in the wood and can therefore handle heavier constructions. For example, this chipboard screw is suitable for hanging brackets that carry heavy items from wooden structures.
