This product is an 18 mm, 6-point deep socket with a 1/2 inch (12.7 mm) square drive, designed primarily to be used with hand ratchets, extension bars and torque wrenches to reach nuts and bolts on extended studs or in recessed locations. The deep profile provides extra reach compared with a standard socket, allowing access over protruding threads while the 6-point (hex) geometry gives secure contact on hexagonal fasteners.

The socket is manufactured from chrome vanadium (Cr-V) steel and is heat treated to provide the strength and toughness required for frequent workshop use. The exterior is bright chrome plated to resist corrosion and to make cleaning easier. The product is produced to common industry dimensional and performance practice for hand sockets and is compatible with DIN/ISO/BS socket tooling standards used across UK industry. Thread type is not applicable for this tool – the socket engages the fastener by its hex profile and connects to drive tools via the 1/2 in square recess; it is suitable for use with ratchets, bars and extensions that accept a 12.7 mm square drive.

Typical applications include automotive maintenance and repair, commercial vehicle servicing, plant and machinery maintenance, construction equipment fitting and agricultural machinery work, as well as general engineering and maintenance tasks in industrial workshops. The 1/2 in drive gives higher torque capacity than smaller drives, making this socket appropriate for medium to heavy duty tightening and loosening where controlled manual torque is required. Note that this style of non-impact chrome vanadium socket is intended for hand-tool use rather than pneumatic or electric impact guns.

Key benefits include excellent corrosion resistance from the chrome finish, robust strength from the Cr‑V material and heat treatment, and superior fastener grip from the 6-point profile which helps reduce rounding of hex heads compared with 12-point alternatives. The standard 1/2 in drive ensures wide compatibility with common hand tool accessories and torque wrenches.
