Extension bar 1/2" 200 mm Honiton H4200

1/2" drive extension bar Honiton H4200, length 200 mm, designed to extend reach for sockets on nuts and bolts in confined or hard-to-reach spaces. Manufactured for use with 1/2" drive ratchets and torque wrenches, it provides reliable torque transfer and increased accessibility for automotive, mechanical and maintenance tasks.

Advantages

The 200 mm extension bar is made to maintain secure connection between socket and drive tool while minimising flex under load. Its 1/2" drive interface fits standard half-inch ratchets and torque wrenches, enabling consistent torque transfer and controlled operation. The extension increases accessibility to recessed fasteners, reducing the need for disassembly of surrounding components and speeding up routine repair and maintenance work.

Suitable for

• Automotive repairs where fasteners are recessed or obstructed.
• General mechanical and engineering maintenance tasks.
• Workshop use with 1/2" drive ratchets and torque wrenches.
• Installation and service jobs in HVAC, plumbing or industrial equipment with limited access.

When it may not be suitable

This extension bar is intended for use with 1/2" drive tools; it is not suitable for smaller or larger drive systems without an appropriate adapter. For applications requiring very high torque or impact-rated use, choose a tool specifically rated for impact or extra-heavy-duty service, since standard extension bars can deform under excessive torque or shock loading.

Key specifications

• Drive size: 1/2" (half-inch).
• Overall length: 200 mm.
• Material and finish: forged steel with corrosion-resistant finish (as supplied by the manufacturer).
• Connection type: square drive to fit sockets and ratchet handles.

How to use

Attach the extension bar to the square drive of a compatible 1/2" ratchet or torque wrench until it seats securely. Fit the desired socket onto the opposite end, then engage the fastener as usual. Use steady, controlled force and avoid sudden impacts. When using a torque wrench, account for the added length if precise torque values are critical, and consult the torque wrench manufacturer guidance for any required correction.

What to consider before purchase

• Compatibility with your existing 1/2" drive tools and sockets.
• Whether an impact-rated extension is required for impact driver applications.
• The effect of added extension length on torque readings when using torque wrenches.

Usage recommendations

Use the extension bar with matched 1/2" sockets and tools, avoid applying impact-type forces unless the tool is specified as impact-rated, and store in a dry place to preserve the corrosion-resistant finish.
