Carpenters Mate pro hexagon head screws have been specifically developed for fixing multiple pieces of timber together. These structurally approved timber screws have an 8mm hex drive head for easy insertion, and a countersunk under the washer-hex head to assist in providing a flush finish. The Carpenters Mate pro hex head screws feature a slash point to reduce timber splittage and remove the need for pre-drilling.

The Technical Stuff
Carpenters Mate pro hex head screws have performed initial type testing under system 3, Annex V of the regulation (EU) no. 305/2011 (Construction Products Regulation), with the reference to the harmonised European standard (hEN) BS EN 14592:2008+A1:2012 (Timber structures - Dowel type fasteners - Requirements) for nails intended for the use in “load bearing timber structures”.
This means that Carpenters Mate hex head screws are fully tested and approved to be used in structural timber applications, replacing a traditional coach screw/coach bolt which are more expensive and time consuming to fit.
