Impact socket accessory Proline ZR18930, length 53 mm

Proline ZR18930 is an impact socket accessory with a length of 53 mm designed for use with impact wrenches and pneumatic or electric impact drivers. Built for demanding workshop and automotive environments, this Proline impact socket delivers a robust connection between tool and fastener and is intended for high-torque fastening and removal tasks. The socket is manufactured from chromium-molybdenum (CrMo) steel offering improved tensile strength and yield point compared with standard chromium-vanadium sockets. Its square drive is compatible with common locking mechanisms used on pneumatic tools.

Advantages

The Proline impact socket features a PRO-DRIVE profile with rounded open angles between the work faces to reduce concentrated point loads on internal edges, which increases torque capacity and reduces the risk of cracking. Forged from CrMo steel, the socket offers extended working life, enhanced resistance to deformation and reliable performance under variable loads. Its standard/elongated geometry and 53 mm length provide better access to recessed fasteners while keeping a secure fit on bolt heads.

Suitable for

• Automotive repair and maintenance where high torque is required
• Industrial assembly and disassembly with impact wrenches
• Pneumatic and electric impact driver applications
• Tasks involving recessed or hard-to-reach fasteners

Key specifications

• Length: 53 mm
• Material: chromium-molybdenum (CrMo) steel
• Drive type: square drive compatible with standard locking mechanisms
• Design feature: PRO-DRIVE rounded internal angles to reduce point loading
• Intended use: impact applications (pneumatic and electric impact drivers/wrenches)

How to use

Select the correct socket size for the fastener, ensure the square drive of the socket is fully engaged with the impact wrench or adapter, and confirm the locking mechanism is secure before operation. Position the socket over the fastener head, apply controlled intermittent impacts where possible, and avoid side loading that could stress the socket walls. After use, inspect the socket for wear or deformation and store it in a dry place or its packaging to prevent corrosion.

Usage recommendations

Use the Proline ZR18930 exclusively with impact-rated tools and sockets; do not use it with hand ratchets or breaker bars that are not rated for impact duty. Periodically check the socket for rounding or cracking at the working faces and replace it if damage is detected. For optimal life, match socket size precisely to fastener heads and avoid excessive torque beyond tool and fastener specifications.
