1/4"-20 Carriage Bolt Hot Dipped Galvanized 307A Grade A

1/4"-20 Hot Dip Galvanized Carriage Bolts

Diameter - Thread Pitch: 1/4-20


1/4"-20 Hot dipped galvanized carriage bolts have a domed or countersunk head, and the shank is topped by a short square section under the head.

  • Square section grips into the part being fixed (typically wood)
  • Prevents the bolt from turning when the nut is tightened
  • Carriage Bolts under 6 inches are fully threaded
  • Sizes over 6 inches in length have a shoulder
  • Coarse Thread
Hot Dipped Galvanized assemblies should be used exclusively. If you use a HDG bolt you must also use a HDG nut.
