UNJF vs UNF Threads – What is the difference Extreme bolt

A This is a great question as UNJ threaded bolts are not interchangeable with a standard UN UNC or UNF nut An internal UNJ thread will assemble to a standard UN external thread but the reverse is not the same due to the interference at the minor diameter The UNJ external threads have a larger root radius than a standard thread pitch
