The 17mm 6‑point deep socket with a 1/2″ square drive is a metric deep socket designed to reach recessed nuts and bolts and to provide a secure 6‑point engagement for hex fasteners. Its primary use is for loosening and tightening 17mm hex nuts and bolts where extra reach is required, typically when studs or recessed heads prevent access with a standard shallow socket.

Manufactured from chrome‑vanadium (CrV) alloy steel and heat treated for strength and toughness, this socket features a bright chrome plated finish to resist corrosion and to allow easy cleaning. The internal hex profile is a 6‑point (6pt) configuration to spread load across the flats of the fastener, reducing the risk of rounding compared with 12‑point designs. The socket accepts a 1/2″ (12.7 mm) square female drive with a spring‑loaded ball detent for positive retention on ratchets, extensions and universal joints. It is produced to industry drive‑tool dimensional and material standards (conforming to recognised DIN/ISO/BS tool specifications for sockets and drives) and is heat treated to provide the torsional resistance needed for workshop and industrial use.

Typical applications include automotive and commercial vehicle maintenance, agricultural machinery, plant and machinery servicing, HVAC and general engineering workshops. The deep length makes it suitable for wheel nuts on certain vehicles, suspension and engine components, and assemblies where washers or protruding stud threads require additional reach. The 6‑point form is particularly appropriate for high‑tension fasteners and repeated use in professional environments.

Key benefits include improved corrosion resistance from the chrome finish, reliable mechanical strength from the CrV material and heat treatment, and secure engagement with a 6‑point profile that reduces fastener damage. The 1/2″ drive compatibility allows use with common professional ratchets, torque wrenches and breaker bars, while the detent mechanism ensures the socket remains attached during use. For safety, observe torque limits for both tool and fastener grade when working with high‑tensile bolts.
