Wera 05066624001 Torq-set Mplus Insert Bit 4 Point

Product Description

The WERA 05066624001 is a Torq-Set Mplus screwdriver insert bit designed for No. 4 point Torq-Set fasteners. The Mplus designation indicates an enhanced tip geometry that improves grip in the fastener recess, reducing cam-out during driving. At 1 inch overall length, this is a standard-format insert bit compatible with 1/4-inch hex bit holders, power screwdrivers, and manual bit handles. It is suited for precision fastener work where Torq-Set drive profiles are specified, a drive type commonly found in aerospace, defense, and specialized mechanical assemblies. The bit weighs 0.1 pounds and is built for repetitive use in demanding trade and service environments.

Torq-Set fasteners are specified in applications where the drive interface must resist rotation under high torque without the fastener backing out. This insert bit is appropriate for aviation maintenance, military equipment servicing, and industrial assembly lines where Torq-Set drive standards are called out. It fits standard 1/4-inch hex quick-change bit holders used by assembly technicians and service professionals working with torque-sensitive fastener specifications.

Installation Notes

Install this bit into a 1/4-inch hex bit holder before use and confirm it is fully seated before applying torque. De-energize or power down any equipment before driving or removing fasteners. Follow applicable torque specifications from the equipment manufacturer or relevant service documentation. Torq-Set drive bits should not be substituted with Phillips or Pozidriv bits, as the drive geometry is not interchangeable.
