Apex 446-1X Phillips Insert Bit No. 1 1/4 in Drive

Product Description

The APEX 446-1X is a No. 1 Phillips screwdriver insert bit designed for use in power tools, impact drivers, and hand drivers with a 1/4 inch hex drive. Built from steel, it measures 1 inch in overall length, making it a compact option for fastening in confined spaces. The short insert format seats directly into 1/4 inch hex chucks and bit holders without an extension, keeping the tool profile low. It is suited for repetitive fastening tasks in mechanical, electrical, HVAC, and plumbing service work where a reliable, correctly sized Phillips bit is required.

This insert bit is a standard fit for trade professionals who work with No. 1 Phillips fasteners on equipment panels, junction boxes, access covers, and light structural components. The 1/4 inch drive shank is compatible with the vast majority of cordless drills, impact drivers, and screwgun bit holders found on job sites. Its 1 inch overall length suits applications where a longer bit would interfere with surrounding hardware or structure.

Compatibility

Installation Notes

Insert bits should be seated fully into the bit holder or chuck before applying torque. Verify that the No. 1 point size matches the fastener recess before driving to prevent cam-out and fastener damage. Inspect the bit tip regularly for wear, and replace when the tip shows rounding or deformation that affects seating. No special tools or certifications are required for bit changes.
