Williams Comfort Products JHWISFX614 Flextension 3/8 Drive

Product Description

The WILLIAMS COMFORT PRODUCTS JHWISFX614 is a Flextension drive extension and socket assembly engineered for engine and heavy equipment manufacturing, assembly, and repair environments. It features a 3/8 inch drive with a 7/16 inch, 6-point socket permanently integrated into the extension body. The non-removable socket design eliminates the risk of the socket separating from the extension during continuous operation. The unit carries a maximum working torque rating of 160 ft-lbs (1,920 in-lbs / 217 Nm) and allows up to 30 degrees of angle offset, giving technicians access to fasteners in confined or angled positions. A black oxide finish provides corrosion resistance. Made in the U.S.A.

This Flextension is suited for production and repair applications where a conventional ball-retained socket-and-extension combination would risk disconnecting under load. It is compatible with hand tools and power tools including impulse and direct-drive tools. It is not rated for impact tool use. Typical install scenarios include engine assembly lines, heavy equipment maintenance bays, and fleet service shops where uninterrupted fastener driving is required. The socket retention pin is TIG welded to ensure full rotational power transfer to the socket. The drive end includes a 7/32 inch cross-hole bevel for ease of tool engagement.
