Carriage Bolt - Square Neck Round Head - Black Oxide & Oil Low Carbon Steel - 1/4"-20 Thread - 5" Long - Pack of 400
Mfr. Model # 1480CB
Carriage bolts feature a square or ribbed neck underneath the head of the fastener and a round head for smooth surface finishes. Carriage bolts are used to bond wood to wood, wood to metal, and sometimes metal to metal. The round head has a domed head, a smaller surface bearing, and protrudes above the fastening surface. Square necks are the standard for carriage bolts. Square necks are designed to prevent the bolt from turning as the nut is tightened. Black oxide steel offers mild corrosion resistance and essentially has no risk of hydrogen embrittlement.
