Century Drill Tool Co Inc 96103 8-32 Nc Hex Die

Product Description

The CENTURY DRILL TOOL CO INC 96103 is an 8-32 National Coarse (NC) machine screw hex die designed for hand cutting external threads on steel, brass, and similar materials. The die is heat treated and tempered to file-hard hardness, delivering precise, consistent thread geometry on each pass. At 1 inch across the flats, it fits standard hex die stocks used in maintenance, fabrication, and repair applications. This is a two-piece package, making it practical to keep a spare on hand. Plumbers, electricians, millwrights, and general tradespeople reach for this die when chasing or cutting 8-32 machine screw threads in the field or shop.

The 96103 is suited for hand threading operations where a bench-mounted die stock or handheld die holder accepts a 1-inch hex die. Common applications include cutting new threads on machine screws, bolts, and threaded rod, as well as cleaning up damaged threads on fasteners used in electrical enclosures, panel hardware, HVAC equipment, and light mechanical assemblies. The 8-32 thread size is one of the most common machine screw standards in electrical and HVAC trade work, making this die a frequent shop and service-van staple.

Installation Notes

A licensed technician or experienced tradesperson should secure the workpiece firmly before threading to prevent movement and ensure straight thread entry. Apply a suitable cutting oil to the die and workpiece to reduce friction, extend die life, and produce cleaner threads. Back off the die periodically during cutting to clear chips and prevent binding. Inspect threads after cutting with a mating nut or thread gauge to verify correct fit before final assembly.
