Unf thread nomenclature
WebUNJ, UNJC, UNJF and UNJEF threads are almost identical to UN, UNC, UNF, and UNEF threads except that the external J thread has a much larger root radius than the standard UN threads and inspection must be performed on this element. The Special UNJ threads are designated by the nomenclature UNJS. WebThe most common types of UN (Unified National) thread are: UNC – Unified National Coarse Thread, comparable with the ISO metric thread. UNF – Unified National Fine Thread. *Compared to standard threads (coarse thread), fine thread has a smaller pitch. Unified threads come in three different classes:

WebFor Metric (mm) threads a tapping-drill size is calculated by subtracting ‘pitch’ from diameter of the thread eg. for 4x.7mm thread: tapping-drill sizes is 4mm dia - .7 pitch = 3.3mm For Imperial (inch) threads a tapping-drill size is calculated by subtracting ‘pitch’ from diameter of the thread eg. for 3/4 x 10 UNC thread is 3/4= .75 ... WebSix Most Common Types of Threads When it comes to different thread types, most people who work in the fluid-power industry will recognize American pipe threads (NPT/NPTF) as well as SAE or Unified threads (UN/UNF). However, threads and connections are divided into six main types: UN/UNF NPT/NPTF BSPP (BSP, parallel) BSPT (BSP, tapered)
