Wera 05066766001 Tri-wing Power Screwdriver Bit

Product Description

The WERA 05066766001 is a Size 4 Tri-Wing power screwdriver bit built for use with 1/4 inch hex drive power tools and impact drivers. The bit measures 1 inch overall length with a 6.20 mm body diameter, making it a compact insert bit suited for production and service applications where Tri-Wing fasteners are encountered. Tri-Wing fasteners are common in consumer electronics, aerospace assemblies, and specialty equipment panels. Licensed electricians, electronics service technicians, and trade professionals working on equipment with proprietary fastener profiles reach for this bit when standard Phillips or Torx profiles will not engage.

This bit is appropriate for use in any environment where Size 4 Tri-Wing fasteners appear, including residential and commercial electronics enclosures, HVAC control panel assemblies, and other specialty equipment using tamper-resistant fastener systems. The 1/4 inch hex shank fits standard quick-change bit holders, power screwdrivers, and drill/drivers. Sold as a single bit.

Installation Notes

Always de-energize and disconnect equipment from power before performing any fastener service on electrical enclosures or control panels. Ensure the bit is fully seated in the quick-change holder before applying torque. Tri-Wing bits should be matched exactly to the fastener size to avoid cam-out and fastener damage. No specialized codes govern bit selection, but follow applicable NFPA 70E safe work practices when working near energized equipment.
