## Summary description

The Proline ZR18446 is a 16mm long hexagonal impact socket with a 1/2" drive, designed for heavy-duty fastening tasks. Engineered for durability and high torque resistance, this tool is compatible with impact wrenches. Its 78mm length provides excellent reach in confined spaces, making it an essential accessory for automotive and industrial maintenance applications.

## Long description

The Proline ZR18446 is a professional-grade 16mm hexagonal long impact socket featuring a standard 1/2" drive. This tool is specifically engineered to withstand the high-intensity forces generated by impact wrenches, making it a reliable choice for demanding mechanical tasks. With a total length of 78mm, it offers the necessary reach to access recessed bolts and fasteners that are otherwise difficult to reach with standard-length sockets.
Advantages
This impact socket is constructed from high-quality materials designed to provide superior durability and resistance to torque-induced wear. Its hexagonal profile ensures a secure fit on bolt heads, minimizing the risk of slipping or rounding off fasteners during high-torque operations. The extended 78mm design significantly improves accessibility in tight engine bays or industrial machinery, allowing for efficient work without the need for additional extensions.
Suitable for
Automotive repair and maintenance
Industrial machinery assembly
Heavy-duty fastening tasks
Working with impact wrenches
When it may not be suitable
This socket is not intended for use with hand tools that require a different drive size, such as 1/4" or 3/8" ratchets, without the use of an adapter. It is also not suitable for applications requiring non-impact sockets, as the wall thickness and material composition are optimized specifically for the vibration and shock of impact tools.
Key specifications
Drive size: 1/2 inch
Socket size: 16 mm
Profile: Hexagonal
Length: 78 mm

How to use
To use the Proline ZR18446, attach the 1/2" drive end securely to your impact wrench anvil. Ensure the socket is fully seated onto the bolt head before activating the tool. Always verify that the socket size matches the fastener to prevent damage to the tool or the bolt. Apply steady pressure and allow the impact wrench to perform the fastening or loosening action.
What to consider before purchase
Verify the drive size of your impact wrench is 1/2 inch.
Confirm that the 16mm size matches your specific fastener requirements.
Ensure the 78mm length is appropriate for the depth of the workspace.
Usage recommendations
Always wear appropriate eye protection when using impact tools. Regularly inspect the socket for signs of wear or cracks, and replace it if any structural damage is observed to maintain safe working conditions.
