Williams Comfort Products JHWISSXM413 Flextension 1/2 in Drive 13MM

Product Description

The WILLIAMS COMFORT PRODUCTS JHWISSXM413 is a Flextension drive extension with an integrated 13 MM, 6-point socket designed for engine and heavy equipment manufacturing, assembly, and repair. The extension and socket are joined in a single non-removable unit, eliminating the risk of socket separation during continuous operation. The socket features SUPERTORQUE lobular openings for increased turning power without deforming fastener heads. Maximum working torque is rated at 160 ft-lbs (1,920 in-lbs / 217 Nm). The drive end includes a 7/32 inch cross hole bevel for easier handling and positioning. Licensed tradespeople and assembly technicians working in production or service environments rely on this tool for reliable, uninterrupted fastening work.

This Flextension is suited for use in engine assembly lines, heavy equipment repair bays, and mechanical service shops where socket separation during operation is a concern. The 1/2 inch drive and 13 MM socket size make it a practical fit for drivetrain, powertrain, and structural fastener applications. It supports up to 30 degrees of angle offset, allowing access to fasteners in tight or angled positions. It is compatible with hand tools and power tools using impulse or direct drive. It is not rated for impact tool use.
