Allgrip HT Set M20 x 70mm, BZP, grade 8.8, supplied in a pack of 25.
Hex head set screws are threaded along the full length of the shank so they can be used in tapped holes or with a nut. High tensile grade suits structural steelwork, machinery, plant and trailer repair where a plain bolt would not hold.
Use a flat washer under the head and tighten with a spanner or socket to the correct torque for the grade.
