Machine bolt

The machine bolt,also named a machine screw bolt,is a cylindrical fastener used to clamp tow pieces of metal together. The bolt consists of a threaded shaft with a square or hexagon shaped head at one end.

Most machine bolts are manufactured from low or medium carbon steel,although bolts made from stainless steel and silicon bronze are available as well,stainless steel and silicon bronze bolts resist corrosion much better than carbon steel ones,and are typically used in applications where they will be exposed to the elements. Aluminum and brass machine bolts are available for specialty applications in the aerospace and marine industries. Machine head bolts are available in both standard and metric sizes,and in left and right headed threads,coarse- and fine-thread varieties are available as well.
