Socket 1/2" 12-point 23 mm Hartsson 17C323Z

Hartsson Socket 1/2" 12-point 23 mm model 17C323Z is a metric twelve-point hand socket designed for use with 1/2-inch drive ratchets and breakers. The 23 mm opening fits hexagonal fasteners and the 12-point design permits engagement at smaller swing angles, improving access in tight areas. Constructed for workshop, garage and industrial maintenance tasks, this socket is intended to provide reliable torque transfer for removing and tightening bolts and nuts in automotive and mechanical applications.

Advantages

The 12-point configuration allows engagement on hex heads at twice the positions compared with a 6-point socket, which reduces the required swing and simplifies work in confined spaces. Designed for 1/2-inch drives, the socket offers compatibility with a wide range of ratchets, extensions and breaker bars. Machined internal geometry ensures a secure fit on fasteners to limit rounding, and durable metal construction delivers resistance to regular workshop stresses and repeated use.

Suitable for

• Automotive repair and maintenance (wheel nuts, engine and chassis fasteners)
• Mechanical assembly and disassembly tasks
• Industrial equipment maintenance and service
• General workshop and garage use with 1/2" drive tools

Key specifications

• Drive size: 1/2 inch (compatible with 1/2" ratchets and extensions)
• Socket type: 12-point
• Nominal size: 23 mm
• Material: heat-treated alloy steel (for strength and wear resistance)
• Finish: corrosion-resistant surface treatment
• Application: metric fasteners (hexagonal bolts and nuts)

How to use

Select the 23 mm socket and attach it securely to a compatible 1/2-inch drive ratchet, breaker bar or extension. Ensure the socket fully seats on the fastener head before applying torque. Use steady, controlled force when loosening or tightening fasteners, and avoid excessive impact on the socket beyond its intended use. For stubborn or rusted fasteners, apply penetrating lubricant and use appropriate safety procedures when increasing leverage.

Usage recommendations

For safe and effective results, pair the socket with tools rated for the same drive size and do not exceed recommended torque values for the fasteners. Store the socket in a dry tool organizer to maintain its finish and inspect regularly for wear or damage before use.
