Apex sockets have hex tolerances that are on average 48% tighter than DIN and 35% tighter than ANSI requirements. With Apex you are assured of an exact, sure fit. All Apex sockets have the tightest tolerances for straightness and concentricity in the industry. Apex industrial grade impact sockets are available in a wide range of lengths and wall thicknesses, and with single or double hex openings. Time-wasting motions are eliminated when starting fasteners or working in hard-to-reach areas. These sockets are identified with a M- prefix. High strength fasteners in demanding situations, like those found in the automotive and aviation industries, often require the use of an impact wrench or impact driver to deliver the amount of torque required to tighten or loosen them.
