It cuts 9/16-18 UNF external threads, which means a 9/16 inch major diameter with 18 threads per inch using the Unified National Fine 60° thread form.
It is for cutting or chasing external threads on rods, bolts, and studs so they fit 9/16-18 UNF nuts and fittings—commonly used in automotive, machinery, and maintenance work.
UNF dies are right-hand unless marked LH. This 9/16-18 UNF die is for standard right-hand threads.
Use a die stock (die wrench) that matches the die’s outside diameter. Secure the die firmly in the holder and apply cutting oil for smoother cutting and longer tool life.
Yes. It produces 9/16-18 UNF threads compatible with standard 9/16-18 nuts and fittings when the thread is cut to proper depth.
9/16 inch is approximately 14.29 mm in diameter. A pitch of 18 TPI equates to about 1.41 mm per thread.
UNF (18 TPI) has finer threads than UNC (12 TPI) at the same diameter, offering finer adjustment and better holding in thin-walled materials.
Bring the rod close to the 9/16 inch major diameter (a few thousandths under), add a 30–45° chamfer to the starting end, and use quality cutting fluid. Advance slowly and back off periodically to break chips.
Yes. It can chase and clean existing 9/16-18 UNF external threads. Start gently, use lubricant, and avoid excessive pressure to prevent removing too much material.
