Index Timberlok wafer head timber construction screws are designed for serious structural timber work. These are the screws you reach for when coach screws feel like overkill but standard wood screws won’t cut it. The wafer head pulls timber faces together with genuine clamping force while sitting nearly flush no proud heads catching on everything.
The patented multi-layer coating handles 1,000 hours of salt spray testing to BS EN 9227:2012, which translates to proper outdoor durability. Use them externally with confidence. The coating also includes a lubrication layer that makes driving noticeably easier, particularly in dense hardwoods or when you’re thirty screws into a long day.
Why Tradespeople Choose These Over Coach Screws
Coach screws need pre-drilling and a spanner. These don’t. The single slash point and 25-degree tip reduce splitting risk even near timber edges, and the TX30 recess gives solid bit engagement without camming out under torque. The helix shank clears debris as you drive, keeping the thread path clean.
The 50-degree deep single thread delivers high pull-out resistance these grip and stay put. Available in 6.7mm and 8.0mm shanks with lengths from 60mm up to 400mm, there’s a size for everything from deck joist connections to structural beam work.
Typical Applications
Timber frame construction, pergolas, carports, garden structures, fence posts to rails, joist hangers, purlin fixings, and anywhere you’d traditionally reach for a coach screw but want the job done faster. The wafer head works particularly well where you need the screw to pull tight without a washer.
Pro Tip: Run the screw in at full speed until the last few turns, then slow right down to seat the wafer head without overtightening you want clamping force, not crushed fibres.
