1/4-20 x 1-1/4 Inch Coarse Zinc Plated A307 Grade A Round Head Step Bolt
Item C38.14.114
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.
