3/8 Inch Drive 6-Point Socket Set with Rails, 42-Piece (5/16-3/4 in., 8-19 mm)
Their extended length allows the deep socket to fit over long fasteners and reach into recessed areas. The large, die-stamped markings are permanently impressed into the material and optimized for readability..Theyre designed to grip the sides and not the corners of the fastener heads, which prevents round-off.
