Wera 05066620001 Torq-set Mplus Insert Bit 2 Point

Product Description

The WERA 05066620001 is a Torq-Set Mplus screwdriver insert bit designed for driving Number 2 Torq-Set fasteners. Torq-Set is a cruciform drive style with offset lobes that require a matched bit - standard Phillips or Pozidriv bits will not engage correctly. The Mplus designation indicates WERA's hardened tool-steel construction with a surface treatment intended to reduce cam-out and extend bit life under powered and hand-drive conditions. At 1 inch overall length, this is a standard insert-bit form factor that seats into 1/4-inch hex bit holders, power screwdriver chucks, and extension bars.

Torq-Set fasteners appear most commonly in aerospace, military, and defense equipment assemblies, as well as certain aviation and avionics panels. This insert bit is suited for technicians and mechanics performing maintenance or assembly work on hardware that specifies Torq-Set drive requirements. The 1-inch insert format is compatible with standard bit holder systems used in both hand-drive handles and pneumatic or electric power tools.

Key Features

• Number 2 Torq-Set Mplus tip matches offset-lobe Torq-Set fastener geometry
• 1-inch overall length in standard 1/4-inch hex insert-bit format
• Hardened tool-steel construction for durability under repeated drive cycles
• Mplus surface treatment reduces cam-out and bit wear
• Compatible with 1/4-inch hex bit holders, handles, and power tool chucks

Compatibility

Designed for use with Number 2 Torq-Set fasteners in any application requiring this drive type. Fits standard 1/4-inch hex bit holders and bit extension bars.

Installation Notes

Torq-Set bits must be matched to the correct point size - using a mismatched bit will damage the fastener head. Seat the insert bit fully into the holder before applying torque. When working on aerospace or defense assemblies, follow the applicable maintenance manual torque specifications and fastener installation procedures. Inspect the bit tip for wear regularly, as a worn Torq-Set tip can cause fastener damage before cam-out is noticeable.
