Impact Extension Bar 1" 250 mm Jonnesway S03A8E10

Jonnesway Impact Extension Bar 1" 250 mm is a heavy-duty extension designed to increase the reach of impact wrenches and pneumatic tools. With a one-inch drive and a 250 mm overall length, this extension bar allows access to fasteners located deep inside wheel hubs, engine compartments, machinery housings, and other recessed or hard-to-reach areas. The bar is engineered to withstand the shock and torsion generated by impact tools while maintaining reliable torque transfer between the tool and the socket.

Advantages

The extension bar features robust construction and heat-treated steel suitable for impact applications, providing durability under repeated shock loading. Its precise machining ensures a secure fit with sockets and drives, reducing play and improving torque transmission. The 1" drive size accommodates heavy-duty sockets and accessories used in automotive, industrial, and equipment maintenance environments. The 250 mm length offers a balance between reach and control without excessively increasing leverage on fasteners.

Suitable for

• Accessing recessed nuts and bolts in automotive wheel hubs and brake assemblies
• Reaching fasteners inside engine bays and transmission housings
• Maintenance and repair of industrial machinery and heavy equipment
• Service work where impact wrenches and pneumatic tools are used

Key specifications

• Drive size: 1 inch
• Length: 250 mm
• Intended use: impact tools (impact wrenches, pneumatic tools)
• Material: heat-treated steel for impact service (manufacturer-stated)
• Connection type: square drive compatible with 1" sockets and accessories

How to use

Attach the 1" end of the extension bar to the drive of an impact wrench or pneumatic tool until it seats securely. Fit an appropriate 1" socket onto the opposite end and engage the fastener. Operate the impact tool following the tool manufacturer's instructions, applying brief bursts of power as needed. Maintain firm control of the tool and extension during operation to ensure accurate torque application and to prevent binding or slipping. Inspect the extension for wear or damage before each use and avoid using it with tools or sockets that do not match the 1" drive specification.

Usage recommendations

Use this extension bar exclusively with tools and sockets designed for 1" drive impact service; avoid using cheater bars or excessive force beyond the tool's rated torque. Store the extension in a dry place and inspect splines and locking detents regularly for deformation or cracking to ensure safe operation.
