Williams Comfort Products JHWISSXM612 Flextension 1/2 in Drive 12MM

Product Description

The WILLIAMS COMFORT PRODUCTS JHWISSXM612 is a Flextension drive extension and socket combination designed for engine and heavy equipment manufacturing, assembly, and repair applications. This 1/2 inch drive, 12 MM, 6-point unit features an integrated, non-removable socket retained by a TIG-welded pin, eliminating the risk of socket separation during continuous operation. The SUPERTORQUE lobular socket opening delivers greater turning power while reducing fastener deformation. Rated to a maximum working torque of 160 ft-lbs (1,920 in-lbs / 217 Nm), it supports up to 30 degrees of angle offset. Licensed mechanics, assembly technicians, and equipment repair professionals rely on this tool for high-cycle, productivity-critical tasks.

This Flextension is suited for use with hand tools and power tools including impulse and direct-drive equipment. It is not rated for impact tool use. The 1/2 inch drive size and 12 MM socket make it appropriate for metric fastener applications commonly found in automotive engines, diesel equipment, and industrial machinery assembly lines. The drive end includes a 7/32 inch cross hole bevel for ease of engagement. The Black Oxide finish provides corrosion resistance in shop and field environments. This unit is manufactured in the U.S.A.
