Century Drill Tool Co Inc 96107 1/4-20 Ns Hex Threading Die

Product Description

The CENTURY DRILL TOOL CO INC 96107 is a 1/4-20 national standard machine screw hex die designed for hand cutting external threads on fasteners and rod stock. The die features precision-cut threads that are accurately formed to produce consistent, exact threading results on each pass. Heat treatment and tempering bring the cutting edges to file-hard condition, extending service life and maintaining thread accuracy over repeated use. At 1 inch across the flats, it seats securely in a standard hex die stock handle. This tool is suited for maintenance technicians, machinists, and trade professionals who need to chase, restore, or cut 1/4-20 NS threads in the field or shop.

The 96107 is intended for hand cutting applications where a tap-and-die set or individual die stock is used to cut or restore external machine screw threads. Typical use cases include thread repair on bolts and threaded rod, fabricating custom-length fasteners, and restoring damaged threads on mechanical assemblies across HVAC, plumbing, electrical, and general maintenance work. The 1/4-20 thread specification is one of the most common unified coarse-thread sizes in North American trade applications, making this die a practical addition to any service kit.
