Extension Bar 1/2" 250 mm JCB

1/2" 250 mm extension bar from JCB is a steel accessory designed to increase reach for 1/2-inch drive sockets. It provides an additional 250 mm of length to access recessed or hard-to-reach fasteners, enabling work in tight engine bays, machinery assemblies, and maintenance environments. The extension bar is intended for use with compatible 1/2" drive ratchets, breaker bars and torque wrenches to transfer turning force while maintaining socket alignment at distance.

Advantages

The JCB extension bar offers extended reach without compromising socket fit or drive engagement. Its solid construction ensures transmission of torque with minimal flex, and the standardized 1/2" drive square makes it compatible with a wide range of sockets and hand tools. The 250 mm length balances reach and control, allowing access to recessed fasteners while preserving leverage and tactile feedback during manual operations.

Suitable for

• Automotive repair and engine maintenance
• Industrial machinery assembly and maintenance
• Home DIY projects requiring deeper access
• Assembly lines and workshop tool kits

Key specifications

• Drive size: 1/2 inch (square drive)
• Length: 250 mm
• Material: hardened steel (chrome finish may be present)
• Compatibility: fits standard 1/2" drive sockets and ratchets
• Connection type: male and female 1/2" square ends for secure engagement

How to use

Select a socket that matches the fastener head and attach it securely to the female end of the extension bar. Connect the male end of the extension bar to a compatible 1/2" drive ratchet, breaker bar or torque wrench. Position the socket on the fastener, ensure square ends are fully engaged, and apply controlled turning force. When using a torque wrench, account for the added length as described by the torque wrench manufacturer to maintain accurate torque readings.

Usage recommendations

Use the extension bar only with tools and sockets rated for the required torque. Avoid sudden impacts or excessive bending loads. Inspect the square ends for wear before use and replace the extension if significant deformation or damage is present.
