3/8-16 x 2-1/2 Inch Coarse Zinc Plated A307 Grade A Round Head Step Bolt

238.38.212

Step bolts, which bolt down wood to wood surfaces, are like a carriage bolt in design. However, step bolts have a wider, lower-profile, round head. Step bolts are preferred for use on wood connections (like decking), where the larger diameter head of the step bolt will not pull through the soft wood.
