Product Detail
  • Product Code :
  • Carriage Bolt
In wood connections, carriage bolts (round head with square neck) are widely utilized. To keep the head from turning, the square neck under the round head will seat into the hole in the wood. Carriage bolts are rarely high strength and are almost usually offered in a normal ASTM A307 specification since they are used with wood.
