Williams Comfort Products JHWISFXT612 Flextension 3/8 in

Product Description

The WILLIAMS COMFORT PRODUCTS JHWISFXT612 is a 3/8 inch drive, 6-point Flextension — an integrated drive extension and socket unit designed for engine and heavy equipment manufacturing, assembly, and repair applications. The socket and extension form a single, non-removable assembly, eliminating the risk of the socket separating from the extension during continuous operation. The JHWISFXT612 features a SUPERTORQUE lobular socket opening that increases turning power while protecting fastener heads from deformation. Maximum working torque is rated at 160 ft-lbs (1920 in-lbs / 217 Nm). Built in the U.S.A. with a durable Black Oxide finish.

This Flextension is suited for production and repair environments where uninterrupted fastener-driving is critical, including automotive engine assembly lines, heavy equipment maintenance bays, and industrial manufacturing facilities. The 3/8 inch drive size covers a broad range of medium-duty fastening tasks. The drive end includes a 7/32 inch cross hole bevel for ease of use, and the unit accommodates up to a 30 degree angle offset to reach fasteners in restricted spaces. It is compatible with hand tools and power tools operating in impulse or direct-drive mode. This product is not rated for impact tool use.

Installation Notes

Installation and use should be performed by qualified mechanics or assembly technicians familiar with fastener torque requirements and drive tool specifications. Confirm the tool and Flextension drive size match before use. Do not exceed the rated maximum working torque of 160 ft-lbs. This unit is not approved for impact tools — using it with an impact driver may cause component failure or injury.
