## Summary description

Proline ZR18420 impact socket accessory, 39 mm length. Designed for use with impact wrenches and pneumatic or electric impact drivers, this socket accessory provides a durable connection between tool and fastener. Suitable for workshop and maintenance tasks where impact-rated components are required to transmit torque reliably.

## Long description

Proline ZR18420 impact socket accessory, length 39 mm, is a hexagonal impact socket designed for use with impact wrenches and pneumatic or electric impact drivers. Constructed from chromium-molybdenum (CrMo) steel, this socket is intended for workshop and maintenance environments where durable, impact-rated accessories are necessary to transfer torque reliably. The Pro-Drive internal profile reduces point loading on fastener edges and allows for higher torque delivery without compromising socket integrity.
Advantages
The CrMo steel construction provides increased tensile strength and a higher yield point compared with standard chromium-vanadium sockets, resulting in longer service life under heavy and variable loads. The specially rounded internal angles of the Pro-Drive system reduce concentrated stress on bolt heads and on the socket’s work planes, lowering the risk of rounding or cracking. The square drive interface is compatible with common locking mechanisms used on pneumatic tools, ensuring secure attachment during impact use.
Suitable for
Automotive maintenance and tyre change work that require impact-rated sockets
Industrial assembly and disassembly tasks with impact wrenches
Workshop repairs and heavy-duty maintenance where higher torque transfer is needed
Applications where protection of bolt heads and extended socket lifetime are priorities
Key specifications
Type: hexagonal impact socket accessory
Length: 39 mm
Material: chromium-molybdenum (CrMo) steel
Internal profile: rounded angles (Pro-Drive system) to reduce point loads
Drive end: square drive compatible with standard locking mechanisms
Intended use: for pneumatic and electric impact drivers and wrenches
Finish: industrial-grade treatment suitable for heavy-duty use
How to use
Select the correct socket size for the fastener and attach the Proline ZR18420 to a compatible impact wrench or driver by engaging the square drive and locking mechanism. Ensure the socket is seated fully on the fastener head before applying torque. Use controlled bursts of power with pneumatic or electric impact tools, allowing the tool to rest between operations to avoid overheating the socket and tool. After use, inspect the socket for cracks or deformation and store it in a dry place or in the original packaging.
Usage recommendations
Use the socket only with tools and fasteners within the rated capacity of your impact driver. Avoid using the socket on corroded or severely rounded fasteners without first assessing fit. Regularly inspect the Proline ZR18420 for wear and replace it if any signs of damage appear to maintain safe and reliable torque transfer.
