DIYUK M12 Hex Head Coach Screws 260mm - Heavy Duty BZP Timber Fasteners - Pack of 20

Manufactured to DIN 571, with the wood-screw thread form conforming to DIN 7998 - the heaviest-duty size in the coach screw range. Hexagon head tightens with a standard 19mm spanner, socket or impact wrench for far higher installed torque than a screwdriver allows. High-tensile carbon steel with a bright zinc-plated (BZP) finish gives general-purpose corrosion resistance for indoor and covered/moderate outdoor use. Coarse, deep wood-screw thread bites directly into timber for high pull-out resistance, with no nut needed on the far side. 19mm head across flats fits every length in the range; used with a wall plug, the same screw also drives into brick, block or concrete.
