Williams Comfort Products JHWBM-1221 Shallow Metric Socket 21 Mm

Product Description

The WILLIAMS COMFORT PRODUCTS JHWBM-1221 is a shallow metric socket designed for fastener removal and installation in tight-clearance applications. Built for a 3/8 inch drive, this socket fits 21 MM fasteners and measures 1.25 inches overall length. The lobular internal opening geometry increases turning power on the fastener while reducing the risk of rounding off hex points. Mechanics, maintenance techs, and trade professionals working on equipment with metric hardware reach for this socket when head clearance is limited.

This shallow socket is suited for use on metric fasteners commonly found in HVAC equipment, plumbing fixtures, pool equipment, and general mechanical assemblies. The shallow profile makes it a practical choice when a standard-depth socket would not clear surrounding components. It engages both 6-point and 12-point fasteners, expanding its range across different fastener types encountered in field service work.

Key Features

• Lobular opening geometry increases torque transfer while protecting fastener corners
• Designed to engage both 6-point and 12-point fasteners
• Shallow profile for use in limited-clearance work areas
• 3/8 inch drive compatible with standard ratchets and extensions
• 21 MM metric sizing for metric fastener applications

Compatibility

Designed as an OEM-style replacement socket for use with standard 3/8 inch drive ratchets and extensions in metric fastener service applications.

Installation Notes

Install and removal of this socket requires a compatible 3/8 inch drive ratchet, breaker bar, or torque wrench. Always power down or de-energize equipment before working on fasteners near electrical components. Confirm the socket is fully seated on the fastener before applying torque to prevent slippage or rounding.
