Williams Comfort Products JHWISSXTM416 Flextension 1/2 in Drive 16MM

Product Description

The WILLIAMS COMFORT PRODUCTS JHWISSXTM416 is a 1/2 inch drive Flextension combining a drive extension and socket into a single integrated unit. The 16 MM, 6-point socket is permanently joined to the extension via a TIG-welded retention pin, eliminating the risk of socket separation during continuous operation. The lobular SUPERTORQUE opening delivers greater turning power while reducing deformation on fastener heads. Rated to a maximum working torque of 160 ft-lbs (1920 in-lbs / 217 Nm), this tool is built for high-demand engine and heavy equipment applications. It is installed and used by assembly technicians, mechanics, and equipment repair professionals.

Flextension tools are used extensively in engine assembly, heavy equipment manufacturing, and repair environments where a standard socket-and-extension combination risks disconnecting under load. The integrated design allows for reliable, continuous work on hand tools and direct-drive or impulse-drive power tools. The drive end features a 7/32 inch cross hole bevel for ease of handling, and the unit supports up to a 30-degree angle offset to reach fasteners in tight or angled positions. This tool is NOT rated for impact tool use.

Installation Notes

This Flextension is intended for use by mechanics and assembly technicians working on engines and heavy equipment. Verify that the drive tool is powered down or disengaged before attaching or removing the Flextension from the drive.
