Wera 05066635001 Torq-set Mplus Insert Bit 5/16 in

Product Description

The WERA 05066635001 is a Torq-Set Mplus screwdriver insert bit designed for use with Torq-Set fasteners, a recessed cross-drive style commonly found in aerospace, defense, and precision mechanical assemblies. The bit features a 5/16 inch point size and an overall length of 1.25 inches, fitting standard 1/4 inch hex bit holders and power screwdriver chucks. The Mplus geometry is engineered to reduce cam-out and maintain consistent engagement under torque load. Licensed technicians and assembly professionals working with Torq-Set fasteners rely on this bit for controlled, repeatable drive performance.

This insert bit is suited for applications where standard Phillips or Pozidriv bits will not engage correctly - specifically assemblies using Torq-Set recessed cross-drive screws. Typical use cases include maintenance and repair work in aerospace component assemblies, military equipment servicing, and specialized industrial equipment. The insert bit format allows quick swapping in standard bit holders, making it practical for both bench work and field service environments.

Installation Notes

Install this bit into a compatible 1/4 inch hex bit holder or power screwdriver before applying torque to Torq-Set fasteners. Confirm the point size matches the fastener recess before driving to avoid fastener or bit damage. De-energize any equipment and follow applicable safety lockout procedures before accessing fastened assemblies. Torq-Set fasteners require the correct drive geometry - substituting a standard Phillips bit will damage the recess.
