Socket extension bar Proxxon 1/2" 250 mm PR23456

Proxxon socket extension bar 1/2" 250 mm PR23456 is a 250 mm long extension bar with a 1/2" drive designed to improve access to recessed or hard-to-reach fasteners in automotive, mechanical and workshop applications. The tool provides a straight, rigid connection between a 1/2" drive ratchet or breaker bar and sockets, enabling torque transfer and controlled operation when working on bolts and nuts located in narrow or deep spaces.

Advantages

The extension bar is manufactured with a solid construction for a precise fit with compatible 1/2" socket sets, reducing play and ensuring reliable torque transmission. Its 250 mm length offers improved reach while maintaining stiffness for controlled force application. The straightforward design ensures compatibility with standard 1/2" drive tools and simplifies access to recessed fasteners without requiring specialized adapters.

Suitable for

• Automotive repair and maintenance where fasteners are recessed or obstructed
• Mechanical assembly and disassembly in workshops
• General workshop use with 1/2" sockets for maintenance and repair tasks

Key specifications

• Drive size: 1/2"
• Length: 250 mm
• Material: chrome-plated steel (solid construction for torque transfer)
• Connection type: square drive compatible with standard 1/2" sockets and ratchets
• Finish: corrosion-resistant surface treatment

How to use

Select a 1/2" socket that fits the fastener, attach the socket to the extension bar square drive, and then connect the extension bar to a compatible 1/2" ratchet or breaker bar. Position the socket on the fastener and apply torque through the ratchet or bar. For removal of tight fasteners, apply steady, controlled force and ensure the socket is fully seated on the fastener head to avoid rounding.

Usage recommendations

Use the extension bar with sockets and drive tools that match the 1/2" standard. Avoid applying impact force unless the bar and socket set are rated for impact use. Keep the square drive and socket engagement surfaces clean and lightly lubricated to prevent corrosion and ensure smooth connection. Inspect the tool regularly for wear or deformation and replace if signs of damage appear.
