The first thread withstanding the load is the highest stressed and the next one is much less stressed and so on If the thread materials were very hard and did not yield the first thread could be withstanding nearly all the load However because of material yielding there is some distribution of the load A study see link 2 below has established that for a typical grade 8 nut 2013 01 19 nbsp 0183 32 turns of thread gauge formula I had it at one time but what is the formula for figuring out how many turns of a thread gauge to determine a depth for example I know for a 1 8 27npsf tap its 1 27 0373 but what is the rest of the formula is I want to know how many turns it takes to get to a depth of 307 Tom s useful info Pitch Conversions Threads per inch Pitch in inches Pitch in mm example 1 4 20 quot taps the 20 signifies quot 20 threads per inch quot 050 pitch 1 divided by 20 So you take the number of steps turn and multiply that with the turns per inch not threads per inch That s it I told you it was simple An example 200 steps turn x 10 turns inch yields 2000 steps inch Remember those turns cancel out Wow Now that s precision Well yes and no depending on the overall mechanical system and backlash reduction Generally the precision 2014 08 24 nbsp 0183 32 In English measurement threads have two numbers to describe them 1 The nominal diameter 2 The number of thread turns in each inch 1 4 250 inch 20 20 turns to advance the thread one inch The pitch is 1 20 inch per turn 05 inch Metric thread usually use you know this for comparison 1 Nominal diameter 2 thread pitch
