Where this product is used

Threading dies cut external threads on rod, bolt, and bar stock — round split dies allow adjustment; hexagonal dies suit die stocks and die holders.

• Cutting external threads on bolts, studs, and rod in workshop and maintenance
• Thread repair and creation on metric, UNC, UNF, and BSW fasteners
• Engineering production, maintenance, and fabrication requiring external thread cutting

Selecting the right option

Split round dies allow adjustment for a range of thread quality from rough to precision. A die stock (handle) is required — confirm it suits the die outer diameter. HSS suits standard steels; HSS-Co for stainless and hard alloys. Always chamfer the end of the rod or bolt before threading — it helps the die start square.
