## Summary description

Proline ZR18938 impact socket accessory with a 57 mm length. Designed for use with impact wrenches and pneumatic or electric fastening tools, this socket accessory provides a compatible connection for torque transfer and fastening operations. Suitable for workshop, automotive maintenance and industrial applications requiring impact-rated components.

## Long description

The Proline ZR18938 impact socket accessory, 57 mm length, is an impact-rated hexagonal socket designed for use with impact wrenches and other pneumatic or electric fastening tools. Manufactured from chromium-molybdenum (CrMo) steel, the socket offers increased tensile strength and yield point compared with standard chromium-vanadium sockets. The Proline design includes rounded internal angles (PRO-DRIVE system) to reduce point loading on fastener corners and to allow higher torque transfer while protecting both the socket and the bolt head.
Advantages
Constructed from CrMo alloy steel for greater durability and longer working life, this impact socket resists deformation under heavy loads. The PRO-DRIVE internal profiling reduces stress concentrations on fastener edges, increasing torque capacity and reducing the risk of socket wall failure. The square drive is compatible with most locking mechanisms used on pneumatic devices, and the socket is supplied in protective packaging to prevent damage in storage and transit.
Suitable for
Automotive maintenance and repair tasks requiring impact-rated sockets
Workshop use with pneumatic and electric impact wrenches
Industrial fastening and assembly operations under variable loads
Key specifications
Overall length: 57 mm
Drive type: square drive compatible with impact tools
Socket shape: hexagonal (6-point)
Material: chromium-molybdenum (CrMo) steel
Design feature: rounded internal angles (PRO-DRIVE system) to reduce point loads
Intended use: impact-rated fastening applications
How to use
Select the correct size hexagonal face on the Proline impact socket for the fastener, attach the socket to a compatible impact wrench using the square drive, and ensure any locking detent or pin is engaged. Use appropriate torque settings for the specific application and follow the impact tool manufacturer’s guidelines. After use, inspect the socket for wear or deformation and store it in its original packaging or on a suitable tool hanger to protect the working surfaces.
Usage recommendations
Use this Proline impact socket only with impact-rated wrenches and accessories. Avoid using the socket on non-impact hand tools where high point loads could cause accelerated wear. Regularly inspect for rounding or cracks, replace if damaged, and apply appropriate lubrication on fasteners to reduce required torque and wear.
