Die UNF 3/8-24 HSS – a compact tool for fine threads
UNF 3/8-24 die is designed to cut external threads with a diameter of 3/8 inch (9.53 mm) and 24 threads per inch. The UNF (Unified National Fine) fine-thread standard offers 50% more threads than its UNC 3/8-16 counterpart, providing a stronger connection and better vibration resistance. HSS construction ensures high durability.
Features of the UNF 3/8-24 fine-thread die
- Fine pitch of 24 threads/inch – 50% more threads than UNC 3/8-16
- Diameter of 9.53 mm – for hydraulics, pneumatics, and precision engineering
- HSS material – effective machining of steel, aluminum, and brass up to 800 MPa
- Conforms to DIN 22568 – European standard for quality and accuracy
- 60° profile – compatibility with the entire Unified thread family
The die is used in hydraulic fitting manufacturing, industrial electronics, and servicing American machinery. The UNF fine thread minimizes the risk of loosening under vibration.
