A product designed for heavy industry, construction companies, and manufacturers of large machinery and equipment. A proven solution for demanding applications.
Frequently asked questions
1 1/2 inch is exactly 38.1 mm. Conversion factor: 1 inch = 25.4 mm. Calculation: 25.4 mm × 1.5 = 38.1 mm.
The Unified system consists of: UNF – fine threads, UNEF – extra fine threads, UNS – special nonstandard threads, and UN – constant-pitch threads: 4, 6, 8, 12, 16, 20, 28, or 32 threads per inch.
The UNC standard has a coarser pitch and fewer threads per inch than UNF. A diameter of 1 1/2 inch has 6 threads per inch in UNC and 12 threads per inch in UNF. Thread pitch gauges are used for measurement.
