Impact socket accessory Proline ZR18821, 50 mm length

Proline ZR18821 impact socket accessory, 50 mm length, is an impact-rated socket designed for use with pneumatic and electric impact wrenches. Manufactured from forged chromium-vanadium steel with controlled hardening and tempering, the socket offers a balance of toughness and wear resistance for repeated high-torque operations. The surface is chrome-plated and polished for corrosion resistance and easy cleaning, while specially profiled edges (PRO-DRIVE system) reduce point loading on fasteners and extend the life of both the socket and the screw head.

Advantages

This Proline impact socket provides standardized connection for fastening and loosening nuts and bolts with impact tools, combining durability and precise geometry. The PRO-DRIVE edge profiling lowers the risk of fastener rounding and distributes torque more evenly across the working planes. Chrome-vanadium construction with heat treatment ensures consistent hardness and resistance to deformation under impact loads. The polished chrome finish offers basic corrosion protection and simplifies maintenance.

Suitable for

• Automotive repair and wheel fastening work
• Machinery maintenance and assembly in workshops
• General workshop fastening tasks requiring impact-rated tooling
• Situations where reduced fastener wear and secure torque transfer are needed

How to use

Select the correctly sized Proline impact socket for the fastener, seat it squarely on the nut or bolt, then attach the square drive end to the compatible impact wrench. Use appropriate torque settings on the impact tool and follow the tool manufacturer's guidance for safe operation. After use, inspect the socket for visible wear or cracks, clean off debris and road grime, and store in a dry place.

Usage recommendations

For safe and reliable performance, use this impact socket only with impact-rated drivers and avoid using it with manual ratchets for high-torque impact applications. Regularly inspect the PRO-DRIVE edges and working faces for rounding or deformation; replace the socket if excessive wear or damage is observed. Clean and lightly lubricate the drive connection to prevent seizing and corrosion.
