DIYUK M6 Hex Head Coach Screws 40mm - Heavy Duty BZP Timber Fasteners - Pack of 20

Manufactured to DIN 571 - a hexagon head coach screw rather than a screwdriver-driven wood screw. Hexagon head tightens with a standard 10mm spanner or socket for far higher installation torque than a screwdriver allows. Steel construction with a bright zinc-plated (BZP) finish gives general-purpose corrosion resistance. Coarse, deep wood-screw thread bites directly into timber for high pull-out resistance, with no nut needed on the far side. 10mm across-flats head fits every length in the M6 range; used with a wall plug, the same screw also drives into brick, block or concrete.
