British Threads - UNF

Both these threads are 60 degree angle Early Harley and Indian motorcycles used 24tpi threads on most diameters 5/16 and 3/8 UNF are both 24tpi but 1/4 UNF is 28 tpi and a special 1/4 x 24 thread must be used. 7/32 x 24 UNC is an obsolete thread. CLASS OF FIT CLASSES OF THREADsmaller, an H1 tap has a tolerance range of from basic to .0005 over basic; an H2 tap from .0005 over basic to .001 over basic, (see chart 1A on this page). In addition, metric threads are also designated in much the same way. The thread tap limits are designated by the letter D (ground, high) above basic pitch diameter, or U (ground

Difference Apr 21, 2020 · 1)The UNF threads have smaller helix angle and better tightness, and it is more conducive to the self-locking of the thread. Therefore, its not that easy to be loosen compared with UNC threads. It is generally used for thin-walled parts and parts with higher anti vibration requirements. 2)The UNF threads have smaller pitch, there are more
