Carriage Bolts and Nuts DIN 603 (Bolt) DIN 934 (Nut) M16 in Bright Zinc Plated (BZP) Steel

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 and DIN 555. Usually manufactured with a full thread, though often some stock may include a partially threaded shank, particularly on longer lengths. Comes complete with hexagon nut to fit.
