is 3 8 whitworth the same as 3 8 unc The Whitworth thread was the world s first national screw thread standard devised and specified by Joseph Whitworth in 1841 Until then the only standardization was what little had been done by individual people and companies with some companies in house standards spreading a bit within their industries Whitworth s new standard specified a 55 thread angle and a thread depth of 0 640327p and a radius of 0 137329p where p is the pitch The thread pitch increases with dia

It turns out that except for 1 2 where the British use 12 threads per inch tpi and Americans use 13 tpi the thread pitches for the rest are the same as for American Unified Coarse UNC However the thread form is Is 3 8 Whitworth the same as 3 8 UNC No they are not the same 3 8 Whitworth and 3 8 UNC Unified National Coarse have different thread profiles and
