The WILLIAMS COMFORT PRODUCTS JHWISSXM913 is a 1/2 inch drive, 13 MM, 6-point Flextension — an integrated drive extension and socket assembly designed for engine and heavy equipment manufacturing, assembly, and repair work. The socket and extension are permanently joined in a non-removable configuration, eliminating the risk of the socket separating from the extension during continuous operation. The socket retention pin is TIG welded to deliver full rotation power transfer to the socket. Maximum working torque is rated at 160 ft-lbs (1,920 in-lbs / 217 Nm). A licensed HVAC technician, mechanic, or assembly professional working in production or field environments will find this tool suited to high-throughput fastener work.
The JHWISSXM913 Flextension is intended for use in engine assembly lines, heavy equipment repair bays, and industrial maintenance applications where continuous, reliable socket engagement is critical. The integrated design supports both hand tools and power tools including impulse and direct-drive tools. It is not rated for impact tool use. The up to 30-degree angle offset capability allows access to fasteners in confined or angled locations common in engine and drivetrain work. Made in the U.S.A.
Designed for use with 1/2 inch drive hand tools and power tools (impulse or direct drive) in engine and heavy equipment manufacturing, assembly, and repair applications. Not for use with impact tools.
Installation and use should be performed by qualified mechanics or assembly professionals familiar with torque specifications and fastener requirements for the application. Before use, confirm the tool is not connected to an impact wrench or impact driver, as this Flextension is not rated for impact tool use. Do not exceed the maximum working torque of 160 ft-lbs (1,920 in-lbs / 217 Nm). Inspect the TIG-welded retention pin and socket joint for wear or damage before each use.
