This is a 13 mm, 3/8" square drive Hi‑Torq 12‑point socket designed for use with 3/8" drive ratchets, torque wrenches, extensions and T‑handles. Its primary use is to fasten and remove 13 mm metric nuts and bolts in confined or precision maintenance environments where repeated engagement and quick indexing are required.

The socket is manufactured from chrome‑vanadium (Cr‑V) steel, heat treated and tempered to provide the torsional strength needed for hand‑tool applications. The external finish is a bright chrome plate, giving good corrosion resistance and simplifying cleaning after use. The socket features a 12‑point (bi‑hex) head profile that allows the user to engage fasteners every 30 degrees, making it easier to access tight spaces compared with 6‑point designs. The drive interface is a standard 3/8" (9.5 mm) square recess compatible with DIN/ISO/BS dimensional standards for hand sockets and accessories, and it will accept standard 3/8" drive locking pins or friction rings where required.

Typical applications include automotive repair, plant and machinery maintenance, assembly workshops, HVAC installations and general engineering tasks. The 12‑point profile is particularly useful on fasteners with limited clearance and for repeated assembly/disassembly operations where speed of engagement is important. While the Hi‑Torq geometry improves contact area and reduces the likelihood of rounding under hand torque, this socket is intended for use with hand tools; it is not specified as an impact‑rated socket for pneumatic or battery impact guns.

Key benefits include durable chrome‑vanadium construction for reliable strength under hand torque, a plated finish for corrosion protection in workshop and site environments, and the 12‑point form for improved accessibility and faster indexing. Compatibility with the widely used 3/8" square drive system makes it easy to mix with existing ratchets and extensions in a mechanic’s toolkit.
