Hello everyone, I'm coming to you because I'd like to know the minimum thickness of material to have around a tap, in M12 for example in steel knowing that there will be no effort, except during tightening of course but with low torque. I am enclosing a very simplified diagram for the purpose of cutting. Thank you.
Hello
For the part; I always try to keep 3 steps of thread to be sure not to have a problem...
Okay but isn't there a more concrete rule in a textbook or other? For example, a thread length of at least 1x the nominal diameter in steel and 1.5 x in aluminum.
Hello
I don't know if there is a precise standard for this but in my opinion for M12 you can at least go down to 2mm of wall as shown on your diagram so in a 16mm diameter, this is the diameter that can be found for example on "RIVKLE"® type rivet nuts.
Kind regards
Okay, thank you!
Just take the example of a tube that screws into the other, even in a diameter of 40mm the thickness is around 2mm, like supports a projector or speaker on a tripod
After that , no particular rule (apart from looking at what is done in other ^^)
Kind regards
For my part, it's very simple, I rely on a nut for example. For an M8 the head diameter is 13 mm so the minimum thickness of the edge is (13 - 6.75)/2 = 3.125
This rule applies to all tapping diameters.
