Carbon Steel Screws for Carpenters by Carpenters

Carpenters Mate is the UK’s original self-drilling wood screw supplier. We supply a collection of carbon steel screws engineered to perform for a range of timber to timber applications.

Our carbon steel screws have been made from quality C1022, a high tensile carbon steel ideal for providing great strength as well as ductility properties.

We also case harden all of our screws to allow for maximum ductility inside the screw whilst increasing the case strength for compatibility with a range of applications. In addition to our case hardening process, we also coat all our carbon steel screws using Geomet® 500 which is proven to withstand 2,000 hours in salt spray.
