Die UN 1 7/16-16 HSS – medium-sized inch die with a pitch of 16 TPI
UN 1 7/16-16 die is a tool designed to produce external threads to the American constant-pitch standard. Made from high-speed steel (HSS) in accordance with DIN 22568, it cuts threads with a diameter of 1 7/16 inches (36.51 mm) and a pitch of 16 threads per inch on shafts and machine components.
Advantages of the UN 1 7/16-16 HSS die
- Constant pitch of 16 TPI – combines fine-thread precision with strength for moderate loads
- HSS high-speed steel – suitable for machining steels up to 800 MPa, as well as aluminum and brass
- Class 2A accuracy per ANSI B1.1 – proper fit with American-standard nuts
- 60° thread profile – compliance with the Unified thread standard
- Manufactured to DIN 22568 – universal compatibility with industrial die stocks
UN 1 7/16 die is used in maintenance facilities and workshops servicing American machinery. A diameter of 36.51 mm with a pitch of 16 TPI provides a solution for joints requiring both precision and adequate load capacity.
Frequently asked questions
A diameter of 1 7/16 inches corresponds to 36.51 mm. The conversion factor is 25.4 mm per inch. Calculation: 1.4375 × 25.4 = 36.51 mm.
UN uses a constant thread count regardless of diameter, unlike UNC and UNF, which have variable pitches. The designation UN 16 always indicates 16 threads per inch for any diameter.
The UN system offers constant pitches: 4, 6, 8, 12, 16, 20, 28, and 32 threads per inch. The choice depends on the characteristics of the joint and its mechanical requirements.
