Die UN 1 1/16-12 HSS – inch threading die with a constant pitch of 12 TPI
UN 1 1/16-12 die is a professional tool for cutting external threads in the American constant-pitch system. Made from high-speed steel (HSS) to DIN 22568, it allows precise cutting of threads with a diameter of 1 1/16 inch (26.99 mm) and 12 threads per inch on shafts and structural bars.
Advantages of the UN 1 1/16-12 die
- Constant pitch of 12 TPI – a versatile thread combining high load capacity with good cutting precision
- HSS high-speed steel – durability when machining steels with tensile strengths up to 800 MPa and nonferrous metals
- Tolerance 2A according to ANSI B1.1 – standard accuracy class for American fits
- Thread angle 60° – full conformity with the Unified thread system
- DIN 22568 – guaranteed quality and compatibility with industrial die holders
UN 1 1/16 die is used in industrial plants and service shops maintaining American-made machinery. The 12 TPI pitch provides a strong threaded connection capable of withstanding high mechanical loads. A tool for tasks requiring reliability.
Frequently asked questions
A diameter of 1 1/16 inch is 26.99 mm. The conversion factor is 25.4 mm per inch. Calculation: 1.0625 × 25.4 = 26.99 mm.
The UN standard uses a constant pitch regardless of thread diameter. In the UNC and UNF systems, the pitch changes with size. UN 12 always means 12 threads per inch for every diameter.
The UN family includes constant pitches of 4, 6, 8, 12, 16, 20, 28, and 32 threads per inch. The pitch is selected based on the strength and precision requirements of the connection.
