UNS 1 1/4-14 HSS die – professional tool for Unified special threads
UNS 1 1/4-14 die 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 1/4-14 die
- Pitch of 14 TPI (1.814 mm) – special pitch for joints requiring increased 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 1/4 inch (31.75 mm) – for heavy structural components and industrial installations
The UNS 1 1/4-14 inch threading die is used in machinery manufacturing, the power industry, and large-bore piping systems. The UNS 1 1/4-14 American-standard die is the choice of professionals working with heavy steel structures. Order a tool that meets the highest quality standards.
Frequently asked questions
The 1 1/4 inch dimension equals 1.25 inches. Calculation: 1.25 × 25.4 mm = 31.75 mm in diameter. A thread count of 14 TPI gives a pitch of: 25.4 mm ÷ 14 = 1.814 mm.
The UNS 1 1/4-14 die is used in heavy industry, the power industry, and hydraulic power systems. It is suitable for threading shafts, sleeves, and machine components with large cross sections.
Large-diameter dies require industrial die stocks. For the 1 1/4 inch size, die stocks for an outside die diameter of 55 mm or 65 mm are used, depending on the manufacturer.
