Williams Comfort Products JHWSMD-1221 Deep Socket 21MM

Product Description

The WILLIAMS COMFORT PRODUCTS JHWSMD-1221 is a metric deep socket designed for high-torque fastener work in professional trade and industrial environments. Built with a 1/2 inch drive, this socket accepts 21 MM fasteners and features a lobular internal opening geometry that increases turning power while reducing the risk of rounding or deforming the fastener head. At 3.2 inches overall length, the deep profile provides the reach needed for recessed fasteners, extended studs, and tight-clearance applications. Licensed tradespeople and mechanical technicians rely on this type of socket for reliable engagement across a wide range of fastener conditions.

This deep socket is suited for general mechanical and industrial maintenance work where metric fasteners are standard. The deep well design accommodates bolt-through applications and is compatible with both 6-point and 12-point fastener heads, making it versatile across HVAC equipment, plumbing fixtures, electrical enclosures, and pool equipment installations where metric hardware is common. It is sold individually and is intended for use with standard 1/2 inch drive ratchets, breaker bars, and torque wrenches.
