Socket 1/2" 18 mm, Hartsson 12-point model 17C318Z

Hartsson 12-point socket 18 mm with a 1/2" drive (model 17C318Z) is a precision tool designed to engage fasteners with a 12-point profile. The socket is compatible with standard 1/2" ratchets and torque wrenches, providing a reliable connection for tightening and loosening bolts and nuts in automotive, industrial maintenance, and general repair settings. Its 12-point geometry allows access to fasteners in tighter spaces and offers multiple engagement angles compared with 6-point alternatives.

Advantages

The 12-point design reduces the need for repositioning on the fastener, enabling quicker adjustments in confined areas. Manufactured to fit a 1/2" drive, this 18 mm socket works with common drive tools and torque devices for controlled fastening. The socket's precise internal profile provides a secure fit on 12-point heads, helping to minimize rounding and slippage during use.

Suitable for (tasks / use cases)

• Automotive repairs and wheel or engine fastener work
• Industrial maintenance and machinery service
• General household and workshop repair tasks where a 12-point socket is required
• Applications requiring use with 1/2" drive ratchets or torque wrenches

Key specifications

• Drive size: 1/2" compatible
• Socket size: 18 mm
• Point profile: 12-point internal geometry
• Intended use: tightening and loosening hexagonal and 12-point fasteners
• Compatibility: standard 1/2" ratchets and torque tools

How to use

Select the 18 mm Hartsson 12-point socket and attach it securely to a compatible 1/2" drive ratchet or torque wrench. Position the socket over the fastener so the 12-point faces align, then apply steady torque in the required direction for tightening or loosening. For torque-critical applications, use a calibrated torque wrench and follow the manufacturer's torque specifications for the fastener to avoid over- or under-tightening.

Usage recommendations

Use appropriate personal protective equipment and select the correct drive and socket size for the fastener. Inspect the socket for wear or damage before use, and avoid applying impact tools unless the socket is specifically rated for impact use.
