Thank you, I will try it out. Greg

Hello All; Not sure this is the place for this question, but.... For this NAS 4002 Spec, Fastener Testing, Table III shows the Nominal Thread size and TPI, the Nominal Size (IN.) and the Thread pitch area at Max Dia. Then the values for Min Tensile for Types I, II and III. Is there a formula for...

Thanks for the reply, I need the table this reference is referring to. As I recall you get the Ratio ( Stress@10%/Ult Stress) then look the n-value up on the chart. It is a really old school way of doing it but handy at times. Greg
