Die UNS 1/4-24 HSS – a professional tool for Unified National Special threads
Die UNS 1/4-24 is a precision cutting tool for producing external inch threads with a 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 1/4-24 die
- Pitch of 24 TPI (1.058 mm) – pitch between UNC and UNF, ideal for special applications
- 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
- Compact diameter of 1/4 inch (6.35 mm) – for small components and precision mechanisms
The UNS 1/4-24 inch threading die is used in precision component manufacturing, electronics, and adjustment mechanisms. The UNS 1/4-24 American-standard die is the choice of professionals requiring nonstandard threaded joints. Order a tool that meets the highest quality standards.
Frequently asked questions
The 1/4 inch diameter converted to millimeters: 1/4 × 25.4 mm = 6.35 mm. A thread pitch of 24 TPI means: 25.4 mm ÷ 24 = 1.058 mm per thread.
The UNC 1/4 thread has 20 TPI, while UNF 1/4 has 28 TPI. The UNS 1/4-24 thread offers an intermediate pitch of 24 TPI for applications requiring a nonstandard pitch.
Threading oil or a coolant emulsion is recommended. For aluminum, use kerosene or paraffin oil. Lubrication extends die life and improves thread quality.
