Die UNS 3/8-26 HSS – a professional tool for Unified National Special threads
Die UNS 3/8-26 is a precision cutting tool for producing external inch threads with a nonstandard, fine pitch. UNS (Unified National Special) denotes a thread with a special combination of diameter and pitch that is unavailable in the standard UNC or UNF series. The tool is made of high-speed steel (HSS) in accordance with DIN 22568.
Key advantages of the UNS 3/8-26 die
- Fine pitch of 26 TPI (0.977 mm) – special pitch for precision joints and thin-walled components
- HSS steel for strengths up to 800 MPa – ensures durability and cutting precision in structural steels, aluminum, and brass
- 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
- Diameter of 3/8 inch (9.525 mm) – versatile size for a wide range of applications
The UNS 3/8-26 inch threading die is used in precision component manufacturing, measuring instruments, and adjustment mechanisms. The UNS 3/8-26 American-standard die is the choice of professionals requiring a fine pitch for accurate joints. Order a tool that meets the highest quality standards.
Frequently asked questions
One inch equals 25.4 mm. For the UNS 3/8-26 thread, calculate: 3/8 × 25.4 mm = 9.525 mm in diameter. A thread count of 26 TPI gives a pitch of: 25.4 mm ÷ 26 = 0.977 mm.
The UNF 3/8 thread has 24 TPI, while UNS 3/8-26 has a finer pitch of 26 TPI. The difference of 2 threads per inch provides more precise adjustment and a stronger joint in thin-walled components.
A fine pitch provides more threads over a given length. This increases joint strength, enables precise adjustment, and reduces the risk of self-loosening under vibration.
