M8 Coach Bolts or M8 Carriage Bolts?

M8 coach bolts may also be known as M8 carriage bolts, dome head bolts, mushroom head bolts, or flat head bolts. They are ideal for use in the construction industry, for decking, and joist construction.

The square neck underneath the head acts as a compression locking device to prevent the bolt head turning during tightening of the nut. The domed head acts as partly a type of security device, because it only allows the bolt to be loosened from one side, and also as a decorative feature. When used on any outward facing area the smooth domed head prevents people catching themselves on the bolt head.
