Socket 1/2" 11 mm Hartsson 17A311Z hexagonal drive

Hartsson 1/2" 11 mm socket (model 17A311Z) is a compact hexagonal socket designed for use with 1/2-inch drive ratchets, extensions and breaker bars. Made to fit 11 mm hex fasteners, it is intended for mechanical, automotive and maintenance work in both professional workshops and home DIY environments. The socket offers a straightforward fit to standard 11 mm bolts and nuts and integrates into common 1/2" drive tool sets.

Advantages

The socket is produced to match standard 1/2" drive dimensions and provides a secure hex engagement to reduce rounding of fasteners. Its compact 11 mm size allows access in confined spaces while maintaining sufficient wall thickness for durability. Compatibility with standard ratchets and extensions ensures easy interchangeability within existing tool sets.

Suitable for

• Automotive repair and maintenance tasks involving 11 mm bolts and nuts
• Mechanical assembly and disassembly in workshops
• Home DIY projects requiring a 1/2" drive socket for medium-strength fasteners

Key specifications

• Drive size: 1/2" compatible
• Socket opening: 11 mm hexagonal
• Shape: 6-point (hex) internal profile
• Intended use: manual hand tool accessory for ratchets and extensions
• Typical applications: automotive, mechanical, maintenance, general repairs

How to use

Attach the socket to a compatible 1/2" drive ratchet, extension or breaker bar until it engages securely. Position the socket over the 11 mm fastener and apply steady turning force with the ratchet or handle. For stubborn or seized fasteners, use controlled, incremental force and consider applying penetrating lubricant before attempting removal. After use, store the socket in a protective tool tray or case to prevent corrosion and maintain fit.

Usage recommendations

Use the socket only with hand tools designed for 1/2" drives and avoid applying impact tools unless the socket is explicitly rated for impact use. Inspect the socket periodically for wear or rounding and replace it if the drive engagement or internal profile becomes damaged.
