## Summary description

Proline ZR18321 impact socket accessory with a length of 28 mm. Designed for use with impact wrenches and pneumatic or electric impact drivers, this accessory serves as a connector/adapter for sockets, enabling secure transfer of torque. Suitable for automotive repair, machinery maintenance and workshop applications requiring impact-rated fittings.

## Long description

The Proline ZR18321 impact socket accessory, 28 mm length, is an adapter designed for use with impact wrenches and electric or pneumatic impact drivers. Manufactured from forged chromium-vanadium steel with precise hardening and tempering, the accessory has a chrome-plated and polished finish and is intended to provide secure transfer of torque between drive tools and sockets. The design includes specially profiled edges between working planes to reduce point loads and protect fastener heads and socket surfaces during heavy-duty use.
Advantages
The Proline impact socket accessory meets or exceeds durability requirements outlined by applicable standards through a heat-treated chromium-vanadium construction, ensuring consistent hardness and resistance to wear. Chrome plating adds corrosion resistance and a smooth surface for easy cleaning. The PRO-DRIVE profiling reduces the risk of fastener rounding and extends both socket and fastener life by distributing load more evenly across contact surfaces. Its compact 28 mm length allows use in confined spaces while maintaining impact-rated strength.
Suitable for
Automotive repair and tire service where impact-rated adapters are required
Machinery maintenance and industrial assembly tasks
General workshop use with pneumatic or electric impact drivers
Situations requiring work in tight or recessed spaces
Key specifications
Material: forged chromium-vanadium steel with heat treatment

How to use
Select an adapter size that matches the drive and socket required for the fastener. Securely attach the Proline ZR18321 to the output square of an impact wrench or driver, then connect the appropriate socket to the adapter. Operate the impact tool according to the tool manufacturer's instructions, applying intermittent operation if required by the task. After use, inspect contact surfaces for wear and clean the chrome finish to remove debris and protect against corrosion.
Usage recommendations
Use only with tools and sockets rated for impact service. Avoid using cheater bars or exceeding the recommended torque of the socket system. Store the adapter in a dry place and inspect regularly for signs of cracking, deformation, or excessive wear before use.
