UN bolts- tensile strength 60,000 psi. Download a free 30 day trial. H= height

root radius of a UNJ external is greater than the max. Yes, theyre great resources, but I wanted things to be a lot closer to my fingertips.

I wanted a higher concentration of useful tools. inspection of the root radii is mandatory. Max.= Basic + PD tol. = .2013 Min = .250 .03248 = .2175, Max.

75% to 80% thread roughly equals 5/8 th of this maximum height. Does both roll tap and cut taps.

Max. 0000052205 00000 n Over time, G-Wizard has become the industrys leading speeds and feeds solution. In fact, what I wanted and needed was a cnc machinist calculator. It uses an advanced algorithm for precise calculations of thread data. Max. (Basic) = Nominal O.D. WebThread Calculator G-Wizards built-in Thread Calculator is loaded with features and information, and its completely free. The UNJ thread series differs from the UN and UNR in the shape of the root, the bottom of the groove between threads. and allowance for the amount to move the three diameters away from The only difference between the internal UNJ thread and the standard UN threaded is that the UNJ thread has a larger minor diameter.
