Impact Socket Accessory Proline ZR18418, Length 39 mm

Proline ZR18418 is an impact socket accessory with a length of 39 mm designed for use with impact wrenches and other power tools. Constructed from chromium-molybdenum (CrMo) steel, this accessory is intended to withstand high torque during fastening and loosening of nuts and bolts in automotive, construction and maintenance applications. The socket features Proline's PRO-DRIVE profile with rounded open angles between work planes to reduce point loads on internal edges and protect bolt heads during heavy use.

Advantages

The CrMo steel construction provides increased tensile strength and a higher yield point compared with standard chromium-vanadium sockets, contributing to longer service life under variable and demanding loads. The PRO-DRIVE internal profiling mitigates stress concentration on corners, enabling higher torque transfer while reducing the risk of socket wall failure and damage to bolt heads. The square drive is compatible with most locking mechanisms used in pneumatic impact tools, and the socket is supplied in simple retail packaging for convenient storage and handling.

Suitable for

• Automotive repair and tyre service
• Construction and assembly tasks involving heavy fasteners
• Industrial and facility maintenance
• Workshops using pneumatic or electric impact wrenches

Key specifications

• Length: 39 mm
• Material: chromium-molybdenum (CrMo) steel
• Design: hexagonal impact socket profile with PRO-DRIVE rounded internal angles
• Drive type: square drive compatible with common locking mechanisms on impact tools
• Intended use: impact torque applications for fastening and loosening nuts and bolts

How to use

Select the Proline ZR18418 socket that matches the fastener size and attach it securely to the impact wrench square drive until the locking mechanism engages. Ensure the impact tool is set to the appropriate torque and direction for the task. Use steady, controlled bursts of the impact wrench rather than prolonged continuous operation to limit heat buildup. After use, inspect the socket for wear or deformation and store it in its packaging or on an appropriate hanger to prevent damage.

Usage recommendations

For extended tool life, avoid using the socket on fasteners that are significantly corroded or rounded; apply penetrating lubricant where necessary and replace the socket if any cracks, significant rounding, or permanent deformation appear. Use appropriate personal protective equipment and follow the impact tool manufacturer's torque and safety guidelines.
