Inch threading die UNS 1-18 HSS – professional tool for Unified special threads
Die UNS 1-18 is a precision cutting tool for producing external inch threads with a large diameter and nonstandard pitch. UNS (Unified National Special) designates a thread with a special combination of diameter and pitch unavailable in standard UNC or UNF series. The tool is made of high-speed steel (HSS) in accordance with DIN 22568.
Key advantages of the UNS 1-18 die
- Pitch of 18 TPI (1.411 mm) – special pitch between UNC and UNF for optimal strength
- HSS steel for strengths up to 800 MPa – provides durability and cutting precision in structural and alloy steels
- Tolerance class 2A according to ANSI – standard accuracy class ensuring proper fit with a 2B nut
- Conforms to DIN 22568 – verified tool manufacturing quality and dimensions
- Large diameter of 1 inch (25.40 mm) – for heavy structural and industrial components
The UNS 1-18 inch threading die is used in heavy industry, the energy sector, and machinery manufacturing. The American UNS 1-18 die is the choice of professionals working with large components requiring a special pitch. Order a tool that meets the highest quality standards.
Frequently asked questions
A diameter of 1 inch is exactly 25.4 mm. A thread pitch of 18 TPI means: 25.4 mm ÷ 18 = 1.411 mm per thread.
The 1-inch UNC thread has 8 TPI, and the 1-inch UNF thread has 12 TPI. The UNS 1-18 thread offers a much finer pitch of 18 TPI for special applications requiring greater precision.
The UNS 1-18 die is used in heavy industry, the energy sector, and hydraulic power systems. It is suitable for threading shafts and sleeves requiring a fine pitch at a large diameter.
