Williams 7-8 Impact Adaptor 1in Female to 1-1/2in Male

Product Description

The WILLIAMS 7-8 is a drive impact adaptor designed to convert a 1 inch female square drive to a 1-1/2 inch male square drive. This adaptor allows technicians and tradespeople to use existing 1 inch drive impact tools with larger 1-1/2 inch drive sockets and accessories without changing out the entire tool setup. Built for impact-rated applications, it handles the high-torque demands common in heavy-duty mechanical, industrial, and trade service work. At 2.558 pounds, the adaptor is solid and substantial, consistent with impact-grade construction. It is sold individually.

This adaptor is suited for heavy equipment service, industrial maintenance, and large-scale mechanical work where both 1 inch and 1-1/2 inch drive tools are in use. It is a practical solution when a technician needs to step up drive sizes mid-job without switching impact wrenches. Typical users include fleet mechanics, millwrights, heavy equipment technicians, and industrial maintenance tradespeople working with large fasteners and high-torque assemblies.

Installation Notes

This adaptor is installed and removed by hand between an impact wrench and a socket. Ensure the impact wrench is fully depowered and the drive retainer pin or ring is properly engaged before use. Inspect the adaptor for cracks or wear before each use, as impact adaptors are subject to significant cyclic stress. Follow applicable OSHA and workplace safety guidelines when operating impact tools at high torque settings.
