Die UNS 1 1/8-24 HSS – special inch die with an extremely fine pitch
UNS 1 1/8-24 die is a professional tool for producing external threads with a nonstandard, extremely fine pitch in the American Unified National Special system. Manufactured from high-speed steel (HSS) in accordance with DIN 22568, it enables cutting of threads with a diameter of 1 1/8 inches (28.58 mm) and a pitch of 24 threads per inch.
Key features of the UNS 1 1/8-24 die
- Extremely fine pitch of 24 TPI – thread count significantly exceeding the UNEF standard (18 TPI) for maximum precision
- UNS special thread – a dedicated solution for applications requiring an unusual combination of large diameter and fine pitch
- HSS construction – capable of machining steels with tensile strengths up to 800 MPa as well as copper and aluminum alloys
- Tolerance 2A in accordance with ANSI B1.1 – standard accuracy class for industrial fits
- DIN 22568 – guaranteed quality and universal fit in threading die holders
Die UNS 1 1/8 is used in high-pressure hydraulics, precision pneumatics, and the production of specialized fittings. Combining a large diameter of 28.58 mm with a fine pitch of 24 TPI provides exceptional sealing and resistance to loosening under vibration.
Frequently asked questions
A diameter of 1 1/8 inches corresponds to 28.58 mm. The conversion factor is 25.4 mm per inch. Calculation: 1.125 × 25.4 = 28.58 mm.
UNS (Unified National Special) denotes a thread with unusual parameters. For a diameter of 1 1/8 inches, the standard pitches are: UNC 7 TPI, UNF 12 TPI, UNEF 18 TPI. The 24 TPI pitch falls outside these series and is therefore classified as UNS.
The Unified system also includes: UNC – the coarse-thread version, UNF – the fine-thread version, UNEF – the extra-fine-thread version, and UN – series with constant thread counts: 4, 6, 8, 12, 16, 20, 28, or 32 per inch.
