• Integrated auto shut-off mechanism for precise torque control and prevention of over-tightening.

Built For

This nut runner is specifically built for assembly operations requiring consistent torque values on fasteners within its 26-159 lbs ins range. It is suitable for tasks involving small to medium-sized fasteners where manual torque wrenches are inefficient or prone to inconsistency. Ideal for electronics assembly, small engine repair, appliance manufacturing, and other light industrial applications where precise, repeatable fastening is paramount.

Construction

The tool’s main body and handle are constructed from a durable, impact-resistant composite material, predominantly black. Metallic silver or light gray accents are present on the collar near the angled head and on the housing at the base of the handle. These metallic components likely indicate reinforced stress points or functional elements of the tool’s internal mechanism.
