Wera 05066642001 Torq-set 8 Power Screwdriver Bit

Product Description

The WERA 05066642001 is a Torq-Set power screwdriver bit designed for use with 1/4 inch hex drive power tools and impact drivers. It drives size 8 Torq-Set fasteners, a specialty cruciform fastener pattern found in aerospace, defense, and precision mechanical assemblies. The bit measures 1 inch overall length with a 6.00 mm body diameter, making it compatible with standard 1/4 inch hex quick-change chucks. This bit is suited for production, maintenance, and field service work where Torq-Set fasteners are specified.

Torq-Set bits are used in applications where standard Phillips or Pozidriv drivers will not engage correctly. This bit is appropriate for aerospace assembly, military equipment maintenance, and specialized OEM assemblies that specify Torq-Set fasteners at size 8. It is typically installed by aviation mechanics, defense maintenance technicians, and precision assembly professionals working in production or field environments. The compact 1 inch length suits confined-space applications and short-reach power drive scenarios.

Key Features

• Size 8 Torq-Set specialty point for precise engagement with Torq-Set fasteners
• 1/4 inch hex drive shank fits standard quick-change power tool chucks

Compatibility

Designed for use with 1/4 inch hex drive power screwdrivers, electric screwdrivers, and impact drivers that accept standard quick-change bit holders. Suitable for driving size 8 Torq-Set fasteners in applications that specify this specialty drive type.

Installation Notes

Insert the 1/4 inch hex shank fully into the quick-change chuck before applying torque. Torq-Set bits require correct alignment with the fastener recess before driving to avoid cam-out or fastener damage. Always match the bit point size to the fastener size as specified by the equipment manufacturer. Follow applicable torque specifications provided by the equipment or fastener manufacturer.
