Die UNS 7/16-24 HSS – special inch die with an intermediate pitch
Die UNS 7/16-24 is a professional tool for cutting external threads with a nonstandard pitch in the American Unified National Special system. Made of high-speed steel (HSS) in accordance with DIN 22568, it cuts threads with a diameter of 7/16 inch (11.11 mm) and a pitch of 24 threads per inch.
Key features of the UNS 7/16-24 die
- Nonstandard pitch of 24 TPI – intermediate thread density between the UNF (20 TPI) and UNEF (28 TPI) standards
- UNS special thread – a solution for specific applications requiring unusual parameters
- HSS high-speed steel – durability when machining structural steels up to 800 MPa 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 7/16 is used for servicing machines imported from the USA, in the aerospace industry, and in the manufacture of specialized fasteners. A diameter of 11.11 mm with a pitch of 24 TPI offers a balance between strength and adjustment precision.
Frequently asked questions
A diameter of 7/16 inch equals 11.11 mm. Conversion uses a factor of 25.4 mm/inch. Calculation: 0.4375 × 25.4 = 11.11 mm.
UNS (Unified National Special) designates a thread with nonstandard parameters. For a size of 7/16 inch, the standard pitches are: UNC 14 TPI, UNF 20 TPI, UNEF 28 TPI. A pitch of 24 TPI does not occur in any of these series, hence the UNS classification.
The Unified system also includes: UNC – coarse threads, UNF – fine threads, UNEF – extra fine threads, and UN – threads with a constant thread count: 4, 6, 8, 12, 16, 20, 28, or 32 per inch.
