Calculating Position Tolerance Values With Fixed Fastener Formula

[robertmartin]

The Fixed Fastener Formula provides the Position tolerance for both parts. You didn't finish the calculation T= .031/2 = 0.0155 for each part. Split 60/40, this would be 0.093 and 0.0062 or ~0.01 & 0.006. This formula does not account for the screw deviation due to straightness or the Position tolerance of thread to body. ASME Y14.5 has a note in the section warning users that the formula does not include these values. Screws from the various industry standards have different geometric tolerances and values, so they cannot easily include these in the text. People should be aware that this simplistic calculation is not complete.

Every type of video you make explains different things. Using a whiteboard helps to understand the steps. I like this electronic board because we can see an actual drawing and the way is presented; a mix of these techniques will improve our understanding. Thank you again. Not many people have the budget to pay for the time of somebody to explain this type of knowledge. I really appreciate these gifts to the Engineering community and myself.

Great video! You’re an awesome teacher!

Can you share your source for the chart you use for your clearance hole tolerances? I would find that very useful.

Hai sir please make a vedio on True position in MMC condition how to work with calypso

Hello, is there anyway we could download this drawing for referencing GD&T?

[printlife]

Thanks a lot! That's very informative! Is there any chance you might demonstrate to replace two screws and holes assembly with two pins and holes assembly with clearance fits, say close running fit H8/f8? I'm searching for info on all kinds of fits applied to GD&T. Unfortunately, I couldn't find it. Thanks in advance.

Can you explain where did you get the tolerance dia .290 +.014/-.009? You mentioned from chart. I can't find a chart that has that tolerance.

[marktrotter]

At 7:45 you said correctly that the Projected tolerance zonce was the maximum thickness of the mating part. But you are calculating the length of the hole for the part the screw goes through. Why is that?

Hi dude, I need more details about datum target and movable datum target usages,
Kindly make videos of it

Idk how Celestial Navigation brought me to Engineering but you're really easy to listen to haha

Mr Odell, I love your work! Do you have a full course for gd&t? Happy to pay.
