Apex 273A-4 Phillips 4 Torq-set Screwdriver Bit 1/4 in Hex

Product Description

The APEX 273A-4 is a power screwdriver bit designed for use with 1/4 inch hex drive power tools and impact drivers. It features a Phillips 4 and Torq-Set specialty point size 4 configuration, making it suitable for driving Phillips-head fasteners in production and service applications. The overall length of 1-13/16 inches provides standard reach for most powered screwdriving tasks. This bit is used by HVAC technicians, electricians, plumbers, and other trade professionals who encounter Phillips fasteners during equipment installation and service work.

This bit fits applications where a 1/4 inch hex drive power screwdriver or drill driver is the tool of choice. The Torq-Set specialty profile makes it appropriate for fasteners found in aerospace, military, and commercial equipment where tamper-resistance or higher torque transfer is required. It is sold as a single-piece unit, suitable for stocking in a service van or shop tool kit alongside standard driver bits.

Compatibility

Designed for use with any 1/4 inch hex drive power screwdriver, drill driver, or bit holder that accepts standard insert bits. Suitable for Phillips 4 and Torq-Set size 4 fasteners.

Installation Notes

Insert the 1/4 inch hex shank fully into the bit holder or chuck before operating the tool. Ensure the bit tip is fully seated in the fastener head before applying torque to avoid cam-out or fastener damage. Inspect the bit tip for wear before each use, as a worn tip on a Phillips or Torq-Set profile can damage fastener heads. Follow applicable safety guidelines for powered hand tools per OSHA and tool manufacturer recommendations.
