Williams Comfort Products JHWISFXTM410 Flextension 3/8 in Drive

Product Description

The WILLIAMS COMFORT PRODUCTS JHWISFXTM410 is a Flextension drive extension with an integrated socket design, built for use in engine and heavy equipment manufacturing, assembly, and repair. The 3/8 inch drive unit accepts a 10 MM, 6-point socket that is permanently fixed to the extension via a TIG-welded retention pin, eliminating the risk of the socket separating from the extension during continuous operation. The socket opening uses a SUPERTORQUE lobular profile to deliver greater turning power while protecting fastener corners from rounding. The drive end includes a 7/32 inch cross hole bevel for easier handling and positioning.

This Flextension is designed for use with hand tools and power tools including impulse and direct drive equipment. It is not rated for impact tool use. A maximum working torque of 160 ft-lbs (1920 in-lbs, 217 Nm) and up to 30 degrees of angle offset make it well suited for confined or angled fastener access in industrial assembly lines, engine bays, and heavy equipment service environments. It is sold individually and is appropriate for use by professional mechanics, assembly technicians, and industrial maintenance personnel.
