Frequently asked questions
1 1/8 inches is exactly 28.58 mm. Conversion: 1 inch = 25.4 mm. Calculation: 25.4 mm × 1.125 = 28.58 mm.
The Unified family also includes: UNF – fine threads, UNEF – extra-fine threads, UNS – special threads with nonstandard dimensions, and UN – constant-pitch threads: 4, 6, 8, 12, 16, 20, 28, or 32 threads per inch.
The UNC standard has a larger pitch and fewer threads per inch than UNF. A 1 1/8 inch UNC thread has 7 threads per inch, while a 1 1/8 inch UNF thread has 12 threads per inch. Verification is performed using inch thread gauges.
