## Long description

The Proline ZR18451 is a professional-grade 1/2-inch drive long hex impact socket, specifically engineered for high-torque applications. With a 21mm opening and a total length of 78mm, this tool is designed to withstand the rigorous demands of impact wrenches, providing reliable performance when fastening or loosening stubborn bolts. Its robust construction ensures longevity and consistent results in demanding work environments.
Advantages
This impact socket is crafted from high-quality materials to resist the extreme stress and vibrations generated by power tools. The extended 78mm length is particularly beneficial for reaching recessed fasteners that are inaccessible with standard-length sockets. Its precise hexagonal profile ensures a secure fit on bolt heads, minimizing the risk of rounding or slippage during high-torque operations.
Suitable for
Automotive repair and maintenance
Industrial machinery assembly
Heavy-duty construction tasks
Removing or tightening recessed lug nuts and bolts
When it may not be suitable
This socket is not intended for use with manual hand tools where high-torque impact force is not required, as its heavy-duty design may be unnecessarily bulky for delicate work. It is also not compatible with impact wrenches featuring a drive size other than 1/2 inch.
Key specifications
Drive size: 1/2 inch
Socket size: 21mm
Length: 78mm
Profile: 6-point (hex)
Compatibility: Impact wrenches
How to use
To use the Proline ZR18451, securely attach the socket to the 1/2-inch anvil of your impact wrench. Ensure the socket is fully seated on the bolt head before activating the tool. Apply steady pressure and operate the impact wrench in short bursts to prevent over-tightening or damaging the fastener. Always ensure the socket is clean and free of debris before use to maintain a proper connection.
What to consider before purchase
Verify that your impact wrench has a 1/2-inch drive output.
Confirm that the 21mm size matches the specific bolt or nut you intend to service.
Check if the 78mm length provides sufficient clearance for your specific application.
Usage recommendations
Always wear appropriate eye and ear protection when operating impact tools. Regularly inspect the socket for signs of wear or cracks, and replace it immediately if any damage is detected to ensure safe operation.
