Our Grade 5 Coarse Carriage Bolts measure 1/4" in diameter and are made from hardened steel with zinc-plating for maximum corrosion resistance. The domed or countersunk head and short square section underneath the head provides a secure grip on the part being fixed, ensuring the bolt won't turn when the nut is tightened.
