Obstructed fasteners slow down the whole job. BoxoUSA’s new 8-Piece 3/8" Drive Universal Impact Extension Socket Sets combine a 12" reach and an integrated universal joint in a single impact-rated tool, built for recessed and offset hardware in engine bays, suspension assemblies, and framework.
Available in metric (BX947-R, 10 to 19mm) and SAE (BX948-R, 5/16 to 3/4"). Chrome molybdenum steel, 6-point engagement, and a black phosphate finish. Each set ships in a CNC-cut two-tone EVA foam insert sized for a 1/3 position in the 26" BoxoUSA drawer, so a missing tool shows up before the drawer closes.
