A structural steel beam connects to the face of support via a single plate shear tab welded with a one-quarter-inch fillet weld typically. The connection uses ASTM A325 bolts sized in diameter and quantity according to the beam depth listed in the standard table. Edge distances measure one and one-quarter inches for three-quarter-inch diameter bolts and two inches for one-inch diameter bolts with a standard three-inch bolt spacing.
