The CENTURY DRILL TOOL CO INC 95104 is a 1/4-28 NF plug-style fractional tap designed for hand cutting applications in metal and similar materials. It features precision-cut threads that are accurately formed to produce consistent, exact threading on each pass. The tool is heat treated and tempered to achieve hardened threads throughout, extending service life under repeated use. This tap is suited for trade professionals and skilled tradespeople who need reliable internal thread creation in 1/4-28 National Fine thread specifications. The package includes 2 taps per unit.

This tap is used when threading 1/4-28 NF internal threads by hand in maintenance, repair, and fabrication work. The plug chamfer style makes it appropriate for through-holes and blind holes where a starting taper is not required but a full plug engagement is needed. Common applications include HVAC, plumbing, electrical, and general mechanical service work where fastener threads need to be cut or restored in the field.

Installation Notes

This tap is installed by a tradesperson using a standard tap wrench. Secure the workpiece before threading and apply appropriate cutting fluid to reduce friction and extend tap life. Back the tap out periodically to clear chips and prevent binding. Do not force the tap if resistance increases sharply, as breakage can occur in hard materials.
