Apex 440-3X Phillips Insert Bit No. 3 1/4 in Drive

Product Description

The APEX 440-3X is a No. 3 Phillips screwdriver insert bit designed for use in power tools and manual drivers with a 1/4 inch hex drive. The bit measures 1 inch in overall length and is machined from steel for durability in demanding fastening applications. At this size, it handles larger Phillips head fasteners commonly found in heavy assemblies, structural components, and industrial equipment. HVAC technicians, electricians, plumbers, and general trade professionals use insert bits like this daily when working with equipment panels, junction boxes, and mechanical enclosures where consistent torque and bit retention matter.

This insert bit is suited for both residential and commercial service work. It fits standard 1/4 inch hex quick-change bit holders, magnetic bit holders, and power screwdriver chucks. The No. 3 point size is the correct fit for larger Phillips head fasteners, including those found on equipment mounting brackets, sheet metal screws in heavy-gauge stock, and structural hardware encountered in mechanical rooms and utility installations. It is sold individually and is straightforward to carry as a spare in a service kit.

Installation Notes

Insert bits should be seated fully into the bit holder before applying torque to prevent cam-out or fastener damage. Inspect the bit tip for wear before use, as a worn Phillips point increases the risk of cam-out and fastener head damage. Replace the bit at the first sign of tip rounding. No special tools or codes apply to bit installation itself, but always follow applicable codes and equipment manufacturer procedures when servicing the equipment the fastener is part of.
