M12 Hex bolts

A M12 Hexagon Bolt, commonly shortened to Hex Bolt, is a 12mm threaded fastener which are constructed from carbon steel with a hexagonal head shape. M12 Hexagon bolts are generally suited for more heavy-duty applications where load strength and life span of the joint are important. We offer flat hex headed, classic domed and drill through M12 hex bolt options, for a variety of DIY projects and installations here at B&Q.
