3/8 X 2 1/4 inch hot dipped galvanized carriage bolts are the outside shorter bolt on the 300B or 300C crossarm clamps. If you are trying to purchase a set of bolts for your crossarm clamps you will need to purchase a 3 1/4 carriage bolt also. These castings use one each of two different sizes. 3/8 X 2 1/4 inch are also the bolts for fastening small or large bottom plates together.
