Allgrip (Bolt, Nut And Washer Assembled) Hex Set M16 x 40mm, supplied in a bag of 50.
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.
