Die UN 1 13/16-8 HSS – large inch die for coarse threads
UN 1 13/16-8 die is a professional tool for cutting large external threads in the American constant-pitch system. Manufactured from high-speed steel (HSS) in accordance with DIN 22568, it enables threading with a diameter of 1 13/16 inches (46.04 mm) and a pitch of 8 threads per inch on shafts and bars with large cross sections.
Key advantages of the UN 1 13/16-8 die
- Coarse pitch of 8 TPI – maximum joint strength for components carrying heavy loads
- HSS construction – durability when machining structural steels up to 800 MPa
- Tolerance 2A in accordance with ANSI B1.1 – standard accuracy class for industrial fits
- Thread profile angle 60° – full compatibility with Unified system fasteners
- DIN 22568 standard – guaranteed dimensions and fit with large die stocks
UN 1 13/16 die is used in heavy industry, machine building, and servicing large equipment manufactured in the USA. A diameter of 46.04 mm with a pitch of 8 TPI is a solution for the most demanding threaded connections.
Frequently asked questions
The 1 13/16 inch dimension is 46.04 mm. Multiplying the inch value 1.8125 by the factor 25.4 mm/inch gives the result in millimeters.
A UN thread has a constant pitch independent of the nominal diameter. UNC and UNF have different thread counts for each size. UN 8 always means 8 threads per inch regardless of diameter.
The UN standard includes constant pitches: 4, 6, 8, 12, 16, 20, 28, and 32 threads per inch. The specific pitch is selected according to load and precision requirements.
