Socket Extension Bar Proxxon 1/2" 250 mm PR23457

The Proxxon 1/2" 250 mm socket extension bar is a hardened steel accessory designed to extend the reach of 1/2-inch drive sockets. Intended for manual or ratchet use, this 250 mm extension provides additional length for accessing recessed, tight, or otherwise hard-to-reach nuts and bolts in automotive, industrial and maintenance applications. The solid construction supports torque transfer while maintaining a slim profile to fit into narrow spaces.

Advantages

The extension bar offers increased reach without compromising strength, allowing reliable torque transmission from ratchets and handles to sockets. Its precise drive fit reduces play between tool and accessory, which improves control when loosening or tightening fasteners. The durable surface finish provides resistance to wear and corrosion from regular workshop use. The 250 mm length balances accessibility and control, making it suitable for a wide range of repair and assembly tasks.

Suitable for

• Accessing recessed nuts and bolts in engine bays and machinery
• Maintenance and repair work where extra reach is required
• Assembly tasks in tight spaces such as equipment housings and frames
• Use with 1/2" drive ratchets, torque wrenches and breaker bars for manual operations

Key specifications

• Drive size: 1/2 inch
• Overall length: 250 mm
• Material: hardened chrome steel (solid construction)
• Finish: corrosion-resistant surface treatment
• Connection: square drive with secure detent fit for sockets and ratchets

How to use

Select a compatible 1/2" drive socket and push it onto the square end of the extension until it engages securely. Attach the extension to a 1/2" ratchet, torque wrench or handle, ensuring the detent or ball lock seats properly. Position the socket on the fastener and apply steady torque; avoid using power tools unless the extension is rated for impact use. After use, remove the extension by pulling the socket off and stow it in a tool rack or toolbox to protect the finish.

Usage recommendations

Inspect the extension for wear or damage before use and ensure compatibility with the applied torque ratings of your drive tools. For best results, use with hand-operated ratchets or torque wrenches and avoid excessive side load or bending forces. Clean and lightly lubricate the square drive periodically to maintain a secure fit and prevent corrosion.
