DifferenceUNF and UNC are two symbols of Unified Screw Thread Series,which defined based on the amount of threads per inch and standardized with gauge.UNF threads are Unified fine pitch threads,while UNC threads are Unified coarse pitch threads.UNF and UNC thread screws are both used for fastening,but mainly applied in different fields.coarse Unified and Metric Thread Forms - Bolt ScienceFor example stating that a thread is M10 indicates a coarse thread series is specified of diameter 10mm (giving the thread a pitch of 1.5mm).The thread form for Unified and Metric threads are identical.If .p = pitch of the thread .d = depth of the thread
