Autobar 8mm x 25mm Allen Bolts Twin Pack 2 Pack

Autobar 608 8mm x 25mm Allen Bolts Twin PackAn Allen bolt, also called an Allen screw bolt or socket head cap screw, has a hexagonal socket recessed into the head rather than an external hex for a spanner. It is tightened or loosened with a matching Allen key or hex bit, which fits into a tighter space than a spanner needs to swing a standard hex head. This differs from hex head bolts, which take a spanner or socket on the outside of the head.This pack contains two 8mm high tensile Allen bolts, each supplied with a matching hex nut and measuring 25mm from under the head to the tip. The 8mm refers to the thread diameter, so check this matches the nut or tapped hole being used. Suits fixing points where a compact head is needed, or where the job calls for an Allen key rather than a spanner.
