Apex 954-C-3X No. 3 Square Recess Power Screwdriver Bit

Product Description

The APEX 954-C-3X is a power screwdriver bit designed for square recess (Robertson-style) fastener driving in professional trade applications. Built with a No. 3 specialty point and a 1/4 inch hex shank, this bit fits standard quick-change power tool chucks and impact drivers commonly used by electricians, HVAC technicians, and plumbers during equipment installation and panel assembly. The overall length of 6 inches provides extended reach in recessed or confined fastener locations. Sold as a single piece, it is suited for both production work and field service where precise square recess drive engagement is required.

This bit is appropriate for use with corded and cordless power screwdrivers and impact drivers equipped with a 1/4 inch hex drive receptacle. The No. 3 square recess profile is commonly encountered on larger sheet metal screws, electrical enclosure hardware, and HVAC equipment panels. It is a practical addition to any service technician kit where No. 3 square drive fasteners are regularly encountered in residential and light commercial installations.

Installation Notes

This bit is installed and removed by hand from any 1/4 inch quick-change hex chuck — no tools required for bit changes. Ensure the power tool is powered off and the trigger is locked out before changing bits. Use the correct No. 3 point size to avoid stripping square recess fasteners; substituting a smaller point size under power load is a common cause of fastener and bit damage.
