Coach Bolts M12 BZP

Generally used in timber to timber and timber to metal construction, these bolts incorporate a square neck to grip the hole in the timber when fitting, and therefore negates the need for any drive recess to be included on top of the head. Supplied to DIN 603. Usually manufactured with a full thread, though occasionally some stock may include a partially threaded shank, particularly on longer lengths. Comes with full nuts.
