## Summary description

Proline ZR18874 is a 400 mm impact socket extension designed for use with impact wrenches and socket sets. Built for transferring torque in heavy-duty fastening tasks, it serves to reach recessed fasteners and extend socket reach. Suitable for professional mechanics and DIY users needing reliable impact-rated extension for workshop and automotive applications.

## Long description

Proline ZR18874 is a 400 mm impact socket extension designed for use with impact wrenches and socket sets. Intended to transfer high torque while accessing recessed or difficult-to-reach fasteners, this extension features a square receptacle on one end and a rounded square pin on the other to ensure compatibility with standard impact sockets and tools. The integrated ball detent holds sockets securely during operation, reducing accidental disengagement and enabling safe extension of tool reach in workshop and automotive environments.
Advantages
The Proline impact extension is manufactured for impact-rated use, providing reliable torque transfer under heavy-duty fastening conditions. Its 400 mm length increases working reach without compromising control, and the ball locking mechanism secures sockets during high-vibration tasks. The rounded square pin design facilitates quick attachment to impact wrenches while the square receptacle accepts common impact sockets, making the extension practical for both professional mechanics and DIY users.
Suitable for
 Accessing recessed or deep-set bolts and nuts in automotive repair
 Workshop maintenance where extended reach is required
 Assembly and disassembly of machinery with obstructed fasteners
 Use with impact wrenches and heavy-duty ratchet drivers
Key specifications
 Length: 400 mm
 Connection type: square receptacle at one end, rounded square pin at the other
 Impact-rated construction for high-torque applications
 Ball detent locking to retain sockets during use
 Compatible with standard impact sockets and impact wrenches
How to use
Select an appropriate impact socket for the fastener, push the socket onto the square receptacle until the ball detent clicks into place, then attach the rounded square pin to the impact wrench or adapter. Position the extension so the socket fully engages the fastener, apply controlled impact torque as required, and avoid side-loading the extension to prevent undue stress. After use, depress the ball detent and remove the socket, and inspect the extension and detent for wear before next use.
Usage recommendations
Use this Proline impact extension with impact-rated sockets and impact tools only; avoid using with non-impact hand tools. Periodically check the ball detent and connection surfaces for wear, and replace the extension if deformation or excessive wear is observed. Wear appropriate eye and hand protection when operating impact tools and follow manufacturer torque guidelines for fasteners.
