The APEX 170-2 is a dual-function power screwdriver bit designed for use with both Phillips and Torq-Set fasteners at a No. 2 point size. It accepts a 1/4 inch hex drive shank, making it compatible with standard power screwdriver chucks, impact drivers, and drill/driver bit holders. The overall length of 1.25 inches keeps it compact for use in tight spaces and bit-extension setups. This bit is commonly used by electricians, HVAC technicians, plumbers, and mechanical contractors who encounter Torq-Set fasteners on OEM equipment and assemblies alongside standard Phillips hardware.
This bit is suited for production, service, and maintenance environments where Torq-Set fasteners appear on commercial and residential equipment. Torq-Set drive systems are common on aerospace-derived components, OEM HVAC assemblies, and specialized mechanical equipment. The No. 2 point size covers the most frequently encountered Torq-Set and Phillips fastener sizes in trade service work. Sold as a single piece, it fits directly into any 1/4 inch hex quick-change bit holder.
Designed as an OEM-style replacement bit for use with any 1/4 inch hex drive power screwdriver, drill/driver, or impact driver accepting standard quick-change screwdriver bits.
Insert the 1/4 inch hex shank fully into the bit holder or quick-change chuck before driving fasteners. Confirm the Torq-Set or Phillips point size matches the target fastener before applying torque to avoid fastener damage. Power down or unplug the driver before changing bits. Follow applicable OSHA hand and power tool safety guidelines during use.
