Stainless Carriage Bolts

These stainless steel carriage bolts have a square neck to help keep the bolt in place during installation. The standard type 18-8 stainless bolts have a completely smooth head (no markings) to give it that nice, finished appearance while the marine grade type 316 option does have 316 stamped on the head. PLEASE NOTE: The 316 stainless carriage bolts are not completely smooth because of the 316 stamp. Length is measured from underneath the head and includes the square neck.
