Apex 170-4 Torq-set Phillips Screwdriver Bit 1/4 in Hex

Product Description

The APEX 170-4 is a power screwdriver bit designed for use with power drivers and impact-rated bit holders accepting a 1/4 inch hex drive. It features a No. 4 Phillips profile combined with a No. 4 Torq-Set specialty point, making it suited for fasteners that require the Torq-Set engagement pattern common in aerospace, defense, and precision assembly work. The overall length is 1-1/4 inches, which positions the bit for standard inline power driver use. This bit is sold as a single piece and is a practical addition to any technician or installer working with specialty fastener types on trade jobsites.

The 170-4 is appropriate for applications where No. 4 Torq-Set fasteners are specified, including panel assembly, equipment enclosures, and other installations that call for tamper-resistant or torque-sensitive fastener engagement. The 1/4 inch hex shank makes it compatible with standard quick-change bit holders and power drivers widely used in electrical, HVAC, and mechanical trade work. Single-piece packaging suits tool bag use and individual replacement without committing to bulk quantities.

Installation Notes

Install this bit into a 1/4 inch hex quick-change driver or bit holder before use. Confirm the fastener head type matches the bit profile before applying power to avoid stripping. Inspect the bit tip for wear before each use, as damaged tips can damage specialty fastener heads. Applicable trade professionals should follow manufacturer guidelines for driver torque settings when working with precision or torque-sensitive assemblies.
