## Summary description

1/2" drive 12-point socket by Hartsson, 11 mm size, model 17C311Z (EAN 5902628171115). Designed for use with 1/2" square drive ratchets and torque wrenches, the 12-point profile allows engagement on fine hex fasteners and in tighter access conditions. Suitable for automotive, machinery maintenance, and general mechanical repair tasks.

## Long description

Hartsson 1/2" 12-point 11 mm socket model 17C311Z is a precision hand tool designed for use with 1/2" square drive ratchets and torque wrenches. The 12-point internal profile permits engagement with fine hexagonal fasteners and offers more approach angles in confined spaces compared with 6-point sockets. This 11 mm socket is intended for automotive repair, machinery maintenance, and general mechanical tasks where compact access and reliable fastening torque are required.
Advantages
The 12-point geometry provides multiple engagement points for quicker alignment on fasteners and easier access in restricted locations. Built for standard 1/2" drive tools, the socket delivers compatibility with common ratchets and torque wrenches used in workshops. The compact 11 mm size is suitable for a wide range of metric fasteners encountered in vehicle and equipment servicing. The construction is engineered to provide consistent fit and transfer of torque while minimising the risk of rounding fastener edges when used appropriately.
Suitable for
 Automotive repairs: engine, suspension, and brake component work
 Machinery and equipment maintenance in workshops and industrial settings
 General mechanical assembly and disassembly tasks
 Situations requiring tighter access where a 12-point profile improves engagement
Key specifications
 Drive size: 1/2" square drive compatibility
 Internal profile: 12-point (double hex) design
 Socket size: 11 mm across flats
 Intended use: hand tools such as ratchets and torque wrenches
 Typical applications: automotive, industrial maintenance, general mechanical repair
How to use
Select the 11 mm Hartsson 12-point socket and attach it securely to a compatible 1/2" drive ratchet or torque wrench. Align the socket with the fastener and apply steady torque, ensuring the tool remains seated on the fastener to reduce slippage. When using a torque wrench, observe the required torque setting for the specific fastener to avoid over-tightening. For removal, back off the fastener while maintaining control of the ratchet to prevent sudden release.
Usage recommendations
For best results, use the socket with the correct 1/2" drive accessories and avoid applying impact tools unless the socket is rated for impact use. Regularly inspect the socket for wear or damage and replace if deformities are found. When working with critical fasteners, follow manufacturer torque specifications and use a calibrated torque wrench.
