Welcome to our range of setscrews and bolts and bolting products. Setscrews or set bolts are fully threaded from the bottom of the head to the bottom of the screw and the size eg 8 x 25 is the diameter of the set screw x the length.
A Bolt is usually partially threaded, this is the rule of thumb. The Threaded part is twice the diameter of the bolt plus 6mm (1/4") Up to 150mm in length eg a 8mm x 75mm bolt would have 22mm of thread.
