DIYUK M8 Hex Head Coach Screws 30mm - Heavy Duty BZP Timber Fasteners - Pack of 5

Manufactured to DIN 571, with the wood-screw thread form conforming to DIN 7998 - a hexagon head coach screw rather than a screwdriver-driven wood screw. Hexagon head tightens with a standard 13mm spanner or socket for far higher installation 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. 13mm across-flats head fits every length in the M8 range; used with a wall plug, the same screw also drives into brick, block or concrete.
