Wiha 28506 Adjustable Torque Screwdriver Handle

Product Description

The WIHA 28506 is an adjustable torque handle designed for use with Wiha TorqueControl interchangeable blades. It provides a selectable torque range of 10 to 50 inch-pounds, allowing technicians to set a precise fastening limit and avoid over-torquing sensitive fasteners. When the preset limit is reached, the handle slips to prevent additional torque from being applied. This makes it well suited for electrical enclosure work, control panel assembly, and equipment servicing where terminal screws and small fasteners require controlled installation. Licensed electricians, HVAC technicians, and instrumentation mechanics are the primary users.

The 28506 handle is intended for trade and light industrial applications where repeatable torque control is required on small fasteners. It pairs exclusively with Wiha TorqueControl blade inserts, making it the handle component of a modular torque screwdriver system. Typical applications include tightening terminal block screws, ground lugs, and other low-torque fasteners in electrical and mechanical assemblies where manufacturer torque specifications must be met.

Key Features

Compatibility

Designed for use with Wiha TorqueControl blades. Consult the Wiha TorqueControl blade catalog to confirm compatible blade inserts for specific drive types and sizes.

Installation Notes

Installation and adjustment should be performed by a qualified electrician, HVAC technician, or instrumentation mechanic familiar with torque-controlled fastening. De-energize any electrical equipment before tightening terminals or fasteners in live panels. Set the desired torque value on the handle before beginning work and verify the slip-clutch engages correctly before applying to the final fastener. Follow applicable NEC or equipment manufacturer torque requirements for the specific terminal or fastener being serviced.
