Carriage Bolt Mushroom Head Bolt for Fastening featurers:
A carriage bolt (also called coach bolt and round-head square-neck bolt is a form of bolt used to fasten metal to metal or metal to wood.
The carriage bolt is more of a bolt than its lag counterpart. The carriage bolt is a straight cylinder with a flat edge. The top has a small square neck that resists turning when it is fastened into place. … The lag bolt, on the other hand, has a point at the end and wide threads for use in wood construction.
Carriage bolts are measured from directly under the head. Sheet metal screw measurement depends upon the type of screw you are using. Countersunk screws (Flat or Oval head) are measured by overall length. Pan Head, truss head, and Hex Head screws are measured from under the head.
