Die UNS 3/8-26 LH HSS – special left-hand inch die with a fine pitch
Die UNS 3/8-26 LH is a specialized tool for cutting left-hand 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 left-hand threads with a diameter of 3/8 inch (9.53 mm) and 26 threads per inch.
Key features of the UNS 3/8-26 left-hand die
- Left-hand thread (LH) – thread direction opposite to standard, preventing self-loosening in rotating mechanisms
- Special pitch of 26 TPI – nonstandard thread count between UNF (24 TPI) and UNEF (32 TPI)
- UNS special thread – a dedicated solution for specific industrial applications
- HSS high-speed steel – capable of machining structural steels up to 800 MPa and nonferrous metals
- DIN 22568 – guaranteed quality and universal fit for die holders
Left-hand die UNS 3/8 is used in machine tool spindles, bicycle pedals, and differentials. Combining a left-hand thread with a fine pitch of 26 TPI provides maximum stability for joints exposed to vibration and reversal of rotation.
Frequently asked questions
A diameter of 3/8 inch corresponds to 9.53 mm. The conversion factor is 25.4 mm per inch. Calculation: 0.375 × 25.4 = 9.53 mm.
UNS (Unified National Special) denotes a thread with nonstandard parameters. For a diameter of 3/8 inch, the standard pitches are: UNC 16 TPI, UNF 24 TPI, UNEF 32 TPI. The 26 TPI pitch falls outside these series and is therefore classified as UNS.
The Unified family also includes: UNC – the coarse-thread version, UNF – the fine-thread version, UNEF – the extra-fine-thread version, and UN – constant-pitch series: 4, 6, 8, 12, 16, 20, 28, or 32 threads per inch.
