Williams Comfort Products JHWISFX414 Flextension 3/8 in Drive

Product Description

The WILLIAMS COMFORT PRODUCTS JHWISFX414 is a Flextension — a combined drive extension and socket unit designed for engine and heavy equipment manufacturing, assembly, and repair. The socket and extension are integrated in a single non-removable assembly, eliminating the risk of the socket separating from the extension during continuous production or repair work. The 3/8 inch drive mates with a 7/16 inch, 6-point socket head featuring SUPERTORQUE lobular openings that apply turning force to the flat faces of a fastener, reducing the chance of rounding. Maximum working torque is 160 ft-lbs (1,920 in-lbs / 217 Nm).

The JHWISFX414 is suited for use in automotive and heavy equipment assembly lines, engine rebuild shops, and general industrial maintenance environments. The 6-point socket configuration is preferred when working with standard hex fasteners in tight or repetitive torque applications. The up-to-30-degree angle offset capability allows access to fasteners that are not in direct line with the drive tool. This Flextension is designed for use with hand tools and power tools operating in impulse or direct drive mode. It is not rated for impact tool use.

Key Features

• Integrated non-removable socket and extension design prevents socket dropout during continuous operation
• SUPERTORQUE lobular socket opening grips fastener flats to reduce rounding under load
• Up to 30 degrees of angle offset for fasteners not in direct line with the drive
• Socket retention pin is TIG welded, ensuring full rotation power transfer to the socket
• Drive end features a 7/32 inch cross hole bevel for ease of engagement
• Durable black oxide finish for corrosion resistance
• Made in the U.S.A.

Compatibility

Designed for use with 3/8 inch drive hand tools and power tools (impulse or direct drive). Not for use with impact tools. Other lengths and socket sizes are available by special order.

Installation Notes

Installation of the JHWISFX414 is performed by technicians working in assembly, manufacturing, or mechanical repair environments. Before use, confirm the drive tool is set to the correct torque for the fastener specification. Do not use this Flextension with impact wrenches or impact drivers, as the assembly is not rated for impact use. Inspect the TIG-welded retention pin and socket-extension joint for wear or damage before each use session.
