Socket 1/2" 26 mm Hartsson 12-point model 17C326Z

Hartsson 12-point socket with a 1/2" drive and 26 mm nominal size, model 17C326Z, is designed for fastening and loosening hexagonal fasteners where a 12-point profile improves access in confined spaces or can engage rounded or damaged heads. The socket fits standard 1/2" drives and is compatible with ratchets, breaker bars and torque tools commonly used in automotive, mechanical maintenance and industrial repair work.

Advantages

The 12-point geometry allows easier positioning on fasteners in tight locations and provides multiple engagement angles compared with a 6-point design. A 1/2" drive offers higher torque capacity for heavy-duty applications while maintaining compatibility with a wide range of drive tools. The nominal 26 mm size corresponds to common metric fasteners, reducing the need for adapter use in metric systems. The design supports steady torque transfer to reduce slipping and minimize further damage to worn fastener heads.

Suitable for

• Automotive repair and wheel, engine or suspension fastener maintenance
• Mechanical workshop tasks involving metric hex fasteners
• Industrial maintenance where access is limited and multiple engagement angles are needed
• Use with torque tools, ratchets and breaker bars requiring a 1/2" drive

Key specifications

• Drive size: 1/2" compatible drive
• Socket profile: 12-point (double hex) geometry
• Nominal size: 26 mm
• Intended fastener type: metric hexagonal bolts and nuts
• Typical applications: automotive, mechanical maintenance, industrial repair

How to use

Select the 26 mm 12-point socket and attach it securely to a 1/2" drive ratchet, breaker bar or torque wrench. Position the socket over the fastener ensuring full seating of the 12 contact points. Apply controlled torque using the drive tool appropriate for the task; avoid sudden impacts beyond the tool’s rated capacity. For loosening, apply steady counterclockwise force and use extension or universal joints if necessary to reach confined areas. After use, clean the socket of debris and store in a socket organizer to preserve fit and finish.

Usage recommendations

Use the 12-point socket when access limits rotation or when fastener corners are damaged; for high-torque applications prefer a proper torque wrench or breaker bar and avoid excessive impact to prolong tool life. Regularly inspect the socket for wear and replace if rounding or cracking appears.
