DIYUK 6.0 x 180mm Torx Wafer Head Structural Timber Screws, Pack of 4 | Self-tapping, wax-coated yellow zinc steel, CE marked to EN 14592, TX30 drive, no washer needed, 12.83kN tensile

EN 14592 and CE marked on every length: structural timber screws manufactured and independently tested to EN 14592:2008+A1:2012, with a declared characteristic tensile capacity of 12.83kN (2,884 lbf) No pre-drilling in most softwoods: self-tapping, with a sharp point that helps prevent splitting, cutting notches that slice through the wood and a reaming cutter that clears shavings so the wafer head seats firmly Wax coating for a faster drive: the wax layer reduces the torque needed for driving, for faster assembly, less effort and savings on the impact drivers and screw guns you use Large 16mm wafer head, no washer needed: the broad bearing surface spreads the clamping load for high pull-through resistance and significantly better load-bearing capacity, chosen for hidden fixings where a flush surface is less critical Partial thread for a tight joint: the thread pulls the two timbers tightly together as it drives, closing any gap; thread length 70mm (2.76in) on the 180mm screw Size and pack: 6.0 x 180mm (7.09in) wafer head wood and timber screws, pack of 4; TX30 Torx drive for a secure, slip-free grip; tempered carbon steel with yellow zinc plating of at least 5 microns For structural timber work: timber frame construction, framing and carcassing, attaching joists and rafters, joining timber and wood-based panels, and hidden structural connections 9 lengths to choose from: 80, 100, 120, 160, 180, 200, 240, 280 and 300mm at a constant 6.0mm gauge, each in packs of 4, 10, 25, 50, 100, 200 or 400
