Apex TW-3 Tri-wing Power Screwdriver Bit Size 3

Product Description

The APEX TW-3 is a Tri-Wing power screwdriver bit designed for use in power screwdrivers and impact-rated drive tools. It features a No. 3 Tri-Wing specialty point that engages Tri-Wing fasteners commonly found in electronics, aerospace assemblies, and specialized mechanical equipment. The 1/4 inch hex shank fits standard 1/4 inch quick-change chucks and bit holders. Overall length is 1-1/4 inches, making it a compact, direct-drive bit suited for confined work areas. This bit is sold as a single piece and is appropriate for technicians and mechanics who encounter Tri-Wing fastener patterns in service and assembly work.

Tri-Wing fasteners are used in applications where tamper resistance or proprietary assembly is required. This bit is well-suited for service technicians working on consumer electronics, avionics panels, and specialty mechanical assemblies. The No. 3 point size targets medium-sized Tri-Wing fasteners. The 1/4 inch hex drive makes it compatible with standard power screwdriver chucks, bit holders, and extension bars used across electrical, HVAC, and mechanical service trades.

Installation Notes

Insert the 1/4 inch hex shank fully into the bit holder or chuck before applying torque. Ensure the fastener recess is clean and free of debris before driving to avoid point wear or cam-out. When servicing energized equipment, de-energize and follow applicable lockout/tagout procedures before use. Inspect the bit tip for wear regularly, as a worn Tri-Wing point can damage specialty fastener recesses.
