Socket bit 1/2" Hartsson 12-point 9 mm (model 17C309Z)

Hartsson 1/2" 12-point socket bit, 9 mm, is a compact drive accessory designed for use with 1/2" ratchets and torque wrenches. The 12-point profile provides multiple engagement angles, allowing access to fasteners in confined spaces and on crowded assemblies. Manufactured to fit standard 1/2" drives, this socket bit is intended for applications that require a small, sturdy tool with reliable contact and repeatable torque transfer.

Advantages

The 12-point geometry reduces the need to reposition the tool, enabling quicker engagement on hexagonal and rounded fasteners. Its 9 mm size is suitable for common metric fasteners, providing a balance of compactness and strength. Made for 1/2" drive systems, the socket bit offers compatibility with a wide range of ratchets and torque devices used in automotive and mechanical environments.

Suitable for

• Automotive repair and wheel service
• Engine and transmission maintenance
• General mechanical assembly and disassembly
• Maintenance tasks in tight or crowded spaces

Key specifications

• Drive size: 1/2" compatible
• Profile: 12-point
• Socket size: 9 mm
• Intended use: ratchets and torque wrenches
• Form factor: single-piece socket bit for insertion into 1/2" drive tools

How to use

Insert the socket bit into a compatible 1/2" drive ratchet or torque wrench until it seats securely. Position the socket over the fastener and apply controlled torque in the required direction. For fastener removal, ensure proper counter-rotation and stable grip; for tightening, follow the torque specifications for the application. Inspect the bit for wear or rounding before use and replace when contact surfaces become damaged.

Usage recommendations

Use the socket bit with tools rated for the intended torque. Avoid applying excessive impact or bending loads that can deform the 12-point profile. Store in a dry environment and keep contact surfaces clean to maintain reliable engagement and extend service life.
