Century Drill Tool Co Inc 95110 Plug Tap 7/16-20 Nf

Product Description

The CENTURY DRILL TOOL CO INC 95110 is a 7/16-20 National Fine (NF) plug-style fractional tap designed for hand cutting applications. It produces internal threads in metal workpieces where a standard plug entry angle is appropriate. The threads are precision cut and accurately formed to deliver consistent, exact threading results on each use. The tap is heat treated and tempered to achieve hard, durable threads and extend working life across repeated cutting operations. At 0.14 pounds, it is a lightweight hand tool suited for bench or field use by machinists, HVAC technicians, plumbers, and maintenance professionals who need reliable thread repair or new thread creation in fractional-inch fastener sizes.

This tap is used wherever a 7/16-20 NF internal thread is needed in metal components. Common applications include thread repair on fittings, brackets, valve bodies, and equipment housings encountered in HVAC, plumbing, and general mechanical maintenance. It is sized for hand-driven use with a standard tap wrench and is sold in a package of 2, making it practical to keep a spare on hand during service calls or shop work.

Installation Notes

A licensed machinist, HVAC technician, or qualified maintenance professional should select the correct tap drill size for a 7/16-20 NF thread before use. Secure the workpiece fully before tapping, and use a calibrated tap wrench to maintain axial alignment. Apply cutting fluid appropriate for the workpiece material to reduce heat and extend tap life. Back the tap out periodically to clear chips and prevent binding or breakage.
