Impact socket accessory Proline ZR18429, 48 mm length

Proline ZR18429 impact socket accessory, 48 mm length, is an impact-rated extension designed for use with impact wrenches and pneumatic or cordless impact drivers. Manufactured from chromium-molybdenum (CrMo) steel, this 48 mm connector provides improved tensile strength and yield point over standard chromium-vanadium sockets, making it suitable for repeated heavy-duty fastening and automotive repair tasks. The accessory is shaped as a hexagonal impact socket with a square drive compatible with common locking mechanisms used in pneumatic devices.

Advantages

The Proline accessory features CrMo construction for increased durability, offering higher tensile strength and an elevated yield point compared with ordinary tool steel sockets. Its PRO-DRIVE profile reduces sharp internal angles between working planes to mitigate stress concentration and wear on bolt heads and socket edges, enabling higher torque application with lower risk of wall crack or deformation. The 48 mm length provides a balance between reach and control when working in confined engine bays or mechanical assemblies.

Suitable for

• Automotive repair and maintenance work
• Mechanical and industrial fastening tasks with impact tools
• Pneumatic and cordless impact driver applications
• Situations requiring impact-rated connectors or extensions

Key specifications

• Length: 48 mm
• Material: chromium-molybdenum (CrMo) steel
• Shape: hexagonal impact socket with square drive
• Design feature: PRO-DRIVE rounded internal angles
• Compatibility: compatible with standard locking mechanisms of pneumatic impact devices

How to use

Attach the Proline 48 mm impact socket accessory to the square drive of a compatible impact wrench or driver, ensuring the locking mechanism engages securely. Position the hexagonal end over the fastener and apply controlled bursts of torque using your impact tool according to the fastener manufacturer’s recommendations. Inspect the accessory and fastener edges periodically for wear, and replace the socket if deformation or cracks are visible to maintain safe operation.

Usage recommendations

For best results, use this impact socket accessory with tools and fasteners rated for impact use; avoid using it with hand ratchets or non-impact drivers. Regularly clean and lightly lubricate the square drive connection to prevent corrosion and ensure reliable locking engagement. Store the accessory in a dry place and replace it if any signs of material fatigue or significant wear are present.
