Williams Comfort Products JHW4M-620 Impact Socket 20MM

Product Description

The WILLIAMS COMFORT PRODUCTS JHW4M-620 is a 20 MM metric shallow impact socket designed for use with 1/2 inch drive pneumatic and electric impact wrenches. Built for high-torque fastening applications, it features SUPERTORQUE lobular openings that maximize contact on 6-point fasteners without deforming the fastener head. The socket is specially heat treated to withstand repeated impact use, extending service life while maintaining structural integrity. Overall length is 1.5 inches, making it a compact option in tight-clearance situations. It is sold individually and suits trade professionals working in mechanical, industrial, and heavy-duty service environments.

This shallow impact socket fits standard 1/2 inch drive impact wrenches and is intended for metric fastening work. Its compact 1.5 inch overall length makes it well suited for applications where a deep socket would not clear surrounding components. Typical use cases include automotive service, equipment maintenance, and industrial assembly work where metric fasteners are common. The heat-treated construction is appropriate for sustained use with high-output pneumatic and electric impact tools.

Key Features

• SUPERTORQUE lobular openings maximize turning power while protecting 6-point fastener heads

Installation Notes

This socket is installed and removed by hand onto a 1/2 inch square drive impact wrench or ratchet. Ensure the socket is fully seated on the drive before applying torque. Inspect the socket for cracks or deformation before each use, as damaged impact sockets should be removed from service. This product is intended for use with impact-rated tools only and should not be used with standard hand ratchets under heavy torque loads.
