Williams Comfort Products JHW37621 Shallow Impact Socket 21MM

Product Description

The WILLIAMS COMFORT PRODUCTS JHW37621 is a metric shallow impact socket designed for use with 1/2 inch drive pneumatic and electric impact wrenches. Sized at 21 MM with an overall length of 1.5 inches, this socket features SUPERTORQUE lobular openings that increase turning power while reducing the risk of fastener deformation. It is specially heat treated for impact service, delivering long service life under high-torque conditions. Licensed trades and industrial mechanics reach for this socket when working with metric fasteners in tight or depth-limited spaces where a deep socket will not fit.

This shallow impact socket is suited for automotive, heavy equipment, and general industrial maintenance applications where metric fastener sizes and impact tooling are standard. The 1/2 inch square drive makes it compatible with a wide range of air impact wrenches and electric torque tools commonly found in professional shops and field service environments. Its compact profile is especially useful in confined areas with restricted axial clearance.

Key Features

• SUPERTORQUE lobular opening design increases turning power and protects fastener heads from rounding
• Engineered for maximum engagement on both 6-point and 12-point fasteners
• Compatible with pneumatic and electric impact wrenches via 1/2 inch square drive
• Specially heat treated for impact use to support long life and safe operation
• Shallow profile suits applications with limited socket clearance depth

Compatibility

Designed as a direct-fit metric shallow impact socket for use with standard 1/2 inch square drive impact wrenches and ratchets.

Installation Notes

Impact sockets should only be used with impact-rated drive tools. Confirm the socket is fully seated on the fastener before applying torque. Do not substitute chrome hand-tool sockets for impact service, as they are not rated for the shock loads produced by pneumatic or electric impact wrenches. Inspect the socket for cracks or wear before each use.
