Williams Comfort Products JHWBM-621 Shallow Metric Socket

Product Description

The WILLIAMS COMFORT PRODUCTS JHWBM-621 is a shallow metric socket designed for use with a 3/8 inch drive ratchet or torque wrench. Built to a 21 MM opening, it features lobular internal geometry that increases turning power while reducing the risk of deforming fastener heads during high-torque applications. The overall assembled length is 1.1 inches, making it well suited for tight-clearance fastening tasks. This socket is intended for professional mechanics, industrial maintenance technicians, and trade professionals who require reliable metric tooling on the job.

The JHWBM-621 is a shallow-profile socket appropriate for both bench work and in-system fastener access where a deep socket would not clear surrounding components. Its 3/8 inch drive interface is compatible with standard ratchets, breaker bars, and torque wrenches in that drive size. The 21 MM size is commonly encountered in HVAC equipment panels, plumbing system hardware, and general mechanical assemblies where metric fasteners are specified.

Key Features

• Lobular opening geometry increases turning power without deforming 6-point fastener heads
• 21 MM metric socket size for common industrial and HVAC hardware applications
• Shallow profile at 1.1 inches overall length for use in confined spaces
• 3/8 inch drive interface fits standard ratchets, extensions, and torque wrenches
• Sold individually (each) with a minimum order quantity of one

Compatibility

Designed as an OEM-style replacement and general-use shallow metric socket compatible with 3/8 inch drive tooling where a 21 MM 6-point metric fastener is encountered.

Installation Notes

Installation and use of this socket should follow standard hand-tool safety practices. Always ensure the socket is fully seated on the fastener before applying torque to prevent slippage or rounding. Power down or de-energize any equipment before accessing fasteners on electrical panels or HVAC components. Use of a calibrated torque wrench is recommended where fastener torque specifications are provided by the equipment manufacturer.
