Apex TW-4 Tri-wing Power Screwdriver Bit Size 4 1/4 in Hex

Product Description

The APEX TW-4 is a Tri-Wing specialty power screwdriver bit designed for use with power drivers and impact tools that accept a 1/4 inch hex shank. The bit features a size 4 Tri-Wing tip profile, an overall length of 1.25 inches, and a 0.25 inch hex drive. Tri-Wing fasteners are commonly found in electronics assemblies, aerospace components, and certain HVAC and appliance equipment where tamper-resistance is required. This bit is a single-piece unit suited for technicians who need a reliable, properly fitted driver for Tri-Wing fasteners during service or assembly work.

This bit is appropriate for professional tradespeople and service technicians encountering Tri-Wing fasteners in residential or light commercial equipment. Typical applications include appliance repair, electronics servicing, and HVAC equipment maintenance where specialty fasteners are used by manufacturers to restrict casual access. The 1/4 inch hex shank fits standard power screwdriver chucks and quick-change bit holders, making it compatible with most cordless drill drivers and dedicated power screwdriver tools used in the field.

Installation Notes

Installation is performed by any technician requiring access to Tri-Wing fasteners during service or equipment assembly. Ensure the tool driver is set to the appropriate torque setting to avoid cam-out or fastener damage. Verify the bit is fully seated in the chuck before applying power. Tri-Wing bits should not be substituted with Phillips or other tip profiles, as improper tip engagement can damage both the fastener and the bit.
