Williams Comfort Products JHW35821 Hex Socket Bit

Product Description

The WILLIAMS COMFORT PRODUCTS JHW35821 is a one-piece impact socket bit designed for heavy-duty fastening and removal applications. Built with a 3/4 inch drive and a 21 MM hex bit size, this socket bit handles high-torque work without the failure risk of two-piece designs. The industrial black finish provides corrosion resistance suited to shop and field environments. At 3.5 inches overall length and a drive end diameter of 1.75 inches, it fits standard 3/4 inch impact tools used by mechanics and trade professionals working on large fasteners across a range of industrial and commercial applications.

This socket bit is used in commercial and industrial settings where large hex fasteners require consistent, high-torque drive. Typical applications include mechanical assembly, equipment maintenance, and structural fastening tasks where a 3/4 inch drive impact tool is standard. The one-piece construction makes it especially well suited for impact wrench use, where two-piece bits are prone to failure under repeated shock loading. Sold individually.

Installation Notes

Installation is performed by qualified mechanics or trade professionals using 3/4 inch drive impact tools or ratchets.
