Sizing 12mm Bolts
12mm length refers to the length of the bolts. Bolt lengths are sized in millimetres. Countersunk bolts are sized inclusive of the head. All hex or coach style bolts are sized from the underside of the head down. All bolts we stock are metric coarse thread pitches, charts can be found on each main product category page with exact thread pitches and thread lengths. We stock all common diameters of bolt, from M3 through to M20 diameters.
