Apex 954-3X Square Recess Screwdriver Bit No. 3 1/4 in Hex

Product Description

The APEX 954-3X is a square recess power screwdriver bit designed for use with power drivers and impact tools in fastening applications. It features a No. 3 specialty point size and a 1/4 inch hex drive shank, with an overall length of 1-15/16 inches. The square recess drive style provides positive engagement with Robertson-head fasteners, reducing cam-out under torque. This bit is a standard single-piece accessory used by electricians, HVAC technicians, plumbers, and general trade professionals wherever square recess fasteners are encountered during installation or service work.

This bit suits residential and light commercial applications where No. 3 square recess fasteners are common, including electrical panel work, HVAC equipment access panels, and sheet metal assemblies. The 1/4 inch hex shank fits standard quick-change bit holders and most cordless power driver chucks. The 1-15/16 inch overall length works in standard bit holders without extension. Sold as a single piece, it is suitable for replenishing existing bit sets or adding a specific size to a tool kit.

Compatibility

Installation Notes

Insert the 1/4 inch hex shank fully into a quick-change bit holder or drill chuck before operating the driver. Ensure the bit point is fully seated in the fastener recess before applying torque to avoid fastener damage. Always de-energize or disconnect equipment before driving fasteners into or around electrical assemblies. Inspect the bit tip for wear periodically, as a worn square recess tip increases cam-out risk.
