Williams Comfort Products JHWISSXTM418 Flextension 18MM

Product Description

The WILLIAMS COMFORT PRODUCTS JHWISSXTM418 is a Flextension socket extension designed for engine assembly, heavy equipment manufacturing, and mechanical repair applications. This tool integrates the drive extension and socket into a single non-removable unit, eliminating the risk of socket separation during continuous or high-output work cycles. It accepts a 1/2 inch drive and features an 18 MM, 6-point socket opening. The maximum working torque rating is 160 ft-lbs (1920 in-lbs / 217 Nm). The socket retention pin is TIG welded to deliver full rotational power transfer. Designed for use with hand tools and power tools including impulse and direct drive equipment.

This Flextension is suited for professional mechanics, industrial assembly technicians, and heavy equipment service professionals working in production or field repair environments. The integrated socket design supports reliable, uninterrupted work in engine bays and equipment frames where socket dropout is a real productivity concern. The 6-point lobular socket opening engages fasteners with reduced risk of rounding. The drive end includes a 7/32 inch cross hole bevel for straightforward attachment. Up to 30 degrees of angle offset allows access in tight or obstructed fastener locations.
