Impact socket accessory Proline ZR18413, 39 mm length

Proline ZR18413 impact socket accessory, 39 mm length, is an attachment designed for use with impact wrenches and pneumatic or electric fastening tools. Manufactured from chromium-molybdenum (CrMo) steel, this hexagonal impact socket is built for demanding workshop repairs, automotive maintenance and industrial assembly tasks where impact-rated tools are required. The socket features PRO-DRIVE rounded internal angles to reduce localized stress on fastener edges and extend service life while maintaining reliable torque transmission.

Advantages

The chromium-molybdenum construction provides increased tensile strength and a higher yield point compared with standard chromium-vanadium sockets, resulting in improved durability under variable loads. The PRO-DRIVE internal profile reduces excessive point loads on bolt heads and socket walls, enabling higher torque application without premature chipping or cracking. The design is compatible with common square drive locking mechanisms used on pneumatic devices, ensuring secure attachment during high-torque operations.

Suitable for

• Automotive repair and wheel servicing where impact-rated sockets are needed
• Workshop maintenance and general mechanical assembly
• Industrial fastening tasks with pneumatic or electric impact tools

Key specifications

• Drive type: square drive compatible with standard locking mechanisms
• Socket shape: hexagonal (6-point)
• Length: 39 mm
• Material: chromium-molybdenum (CrMo) steel
• Internal profile: PRO-DRIVE rounded angles to reduce point loads
• Intended use: impact-rated applications with pneumatic or electric wrenches

How to use

Select the correct socket size to match the fastener head, then attach the socket to the impact wrench square drive until the locking mechanism secures it. Operate the impact tool following the tool manufacturer's guidelines, applying steady control and avoiding excessive side loading on the socket. After use, inspect the socket for wear or deformation, especially around the working faces and the drive connection, and store it in a dry place to prevent corrosion.

Usage recommendations

Use this Proline impact socket with compatible impact-rated tools and avoid using it with hand ratchets or non-impact drivers to prevent damage. Periodically check the socket and fasteners for wear; replace the socket if cracking, rounding, or significant deformation is detected. For best results, pair the socket with suitably sized impact-rated extensions and adapters designed for heavy-duty applications.
