Williams Comfort Products JHW6M-1221 Shallow Impact Socket

Product Description

The WILLIAMS COMFORT PRODUCTS JHW6M-1221 is a metric shallow impact socket designed for use with pneumatic and electric impact wrenches in professional trade and industrial applications. Built around a 3/4 inch drive and sized at 21 MM, this socket features a 2 inch overall length profile suited for tight-clearance fastening work. The lobular internal geometry distributes torque across the fastener faces rather than corners, reducing fastener deformation under high-torque conditions. Specially heat treated for impact use, it delivers consistent performance and extended service life under the demands of daily shop or field work.

This socket is appropriate for heavy-duty fastening tasks in automotive, mechanical, and industrial maintenance settings where a 3/4 inch drive impact tool is the standard. The shallow profile makes it a practical choice when deep-socket clearance is unavailable or unnecessary. Licensed technicians, millwrights, and professional mechanics working with metric fasteners in the 21 MM range will find this socket a direct fit for impact-driven applications. Sold individually, it integrates into existing 3/4 inch drive socket sets.

Key Features

• SUPERTORQUE lobular openings distribute load across fastener flats to reduce deformation
• Compatible with 6-point and 12-point fasteners for broad application coverage
• Rated for use with pneumatic and electric impact wrenches
• Specially heat treated for impact service, improving durability and safety under high torque
• Drive end includes pin retention hole and groove for secure tool retention
• Shallow profile at 2 inches OAL suits confined or low-clearance fastening scenarios

Compatibility

Designed as an OEM-style impact socket for use with standard 3/4 inch drive pneumatic and electric impact wrenches accepting metric shallow sockets.

Installation Notes

Installation and use should be performed by a qualified mechanic or tradesperson familiar with impact tooling. Always ensure the impact wrench is powered down and the air supply is disconnected before attaching or removing the socket. Verify the pin retention groove is fully engaged before applying torque. Do not use impact sockets with hand-drive ratchets, as impact-rated sockets are not designed for that application.
