This 32 mm deep impact socket with a 1/2" (12.7 mm) square drive is a heavy-duty socket designed to be used with pneumatic, battery or electric impact wrenches and 1/2" drive breaker bars. Its primary use is to reach recessed nuts and bolts in automotive, agricultural and industrial assemblies where extra depth is required to clear studs, flanges or protruding threads.

The socket is manufactured from chromium‑molybdenum (Cr‑Mo) alloy steel that has been heat treated and tempered for increased impact resistance and torsional strength. It features a 6‑point (hex) internal profile to distribute load across the flats of fasteners, reducing the risk of rounding. The external surface is finished with a black phosphate/oxidised coating to inhibit corrosion and to withstand the harsher environment associated with impact tool use. The square drive is 1/2" (12.7 mm) to fit standard anvil connections and includes a retaining groove to accept standard drive pins or detent balls.

Dimensions and profiles are manufactured to standard socket geometry, compatible with DIN/ISO square‑drive socket dimensions and conforming to relevant British Standards recommendations for hand and impact tool safety. This socket is intended for use on coarse‑thread and metric hex fasteners and is not suitable where precision torque calibration is required without a torque limiting device.

Typical applications include car and commercial vehicle repair, agricultural machinery maintenance, plant and machine maintenance, construction equipment servicing and motorsport pit work. The deep format is particularly useful for wheel nuts on dual‑wheel hubs, studded assemblies and when working over shanks or washers. The combination of Cr‑Mo construction and phosphate finish offers a balance of strength and corrosion protection, while the 6‑point profile improves compatibility with worn or high‑torque fasteners.
