Die UNS 1/2-24 HSS – special inch die with a fine pitch
Die UNS 1/2-24 is a specialized tool for cutting external threads with a nonstandard fine pitch in the American Unified National Special system. Made from high-speed steel (HSS) in accordance with DIN 22568, it cuts threads with a diameter of 1/2 inch (12.7 mm) and a pitch of 24 threads per inch.
Key advantages of the UNS 1/2-24 die
- Fine pitch of 24 TPI – closely spaced threads between the UNF (20 TPI) and UNEF (28 TPI) standards for precision applications
- UNS special thread – a solution for components requiring an unusual thread count
- HSS high-speed steel – durability when machining structural steels up to 800 MPa and non-ferrous metals
- Tolerance 2A in accordance with ANSI B1.1 – standard accuracy class for industrial fits
- DIN 22568 standard – dimensional reliability and compatibility with die holders
Die UNS 1/2-24 is used in precision engineering, measuring instruments, and servicing equipment imported from the USA. The 24 TPI pitch provides increased vibration resistance and improved sealing of threaded connections.
Frequently asked questions
A diameter of 1/2 inch equals 12.7 mm. The conversion factor is 25.4 mm per inch. Calculation: 0.5 × 25.4 = 12.7 mm.
UNS (Unified National Special) is a thread with a nonstandard combination of diameter and pitch. For the 1/2 inch size, the standard values are: UNC 13 TPI, UNF 20 TPI, UNEF 28 TPI. The 24 TPI pitch does not occur in any of these series.
The Unified system includes: UNC – coarse threads, UNF – fine threads, UNEF – extra-fine threads, UN – constant-pitch threads, and UNS – threads with special parameters.
