M12 x 150mm A4 Marine Grade Stainless Steel Coach Bolts with Nuts and Form A Washers, Pack of 8
Pack of eight M12 x 150mm fully threaded coach bolts to DIN 603 in A4 (316) marine grade stainless steel, supplied with matching stainless steel nuts and Form A washers. A4 is the stainless steel grade used for salt water and coastal environments, so these are a marine grade fixing. Coach bolts have a domed head and a square neck that grips the timber, so the bolt doesn't turn as you tighten the nut.
