Apex 27mm 12-Point Metric Standard Socket, 1/2” Square Drive Description

Apex sockets have hex tolerances that are on average 48&#37 tighter than DIN and 35&#37 tighter than ANSI requirements. With Apex you are assured of an exact, sure fit. 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.

Apex impact sockets are specifically designed and manufactured for high impact use, and made from a tougher and more ductile alloy steel which is then heat treated for extra durability.
