TIMco In-Dex Timber screws are designed for decking, stairs, fencing, roofing, railway sleepers, and many other landscaping applications. The 8mm hex head with a fixed washer provides excellent clamping in all wood types. Made from A4 marine grade stainless steel to withstand up to 1,000 hours (min) salt spray resistance. They have a 50-degree deep single thread to provide secure fixing with a high pull-out resistance and a type 17 slash to reduce torque and the likelihood of the timber from splitting when the screw is inserted close to the edge. They also have a 25-degree sharp point for easier penetration into all wood types.

This listing is for a full box of 25 screws

The Technical Stuff

TIMco In-Dex screw has 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 TIMco In-Dex 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.
