so it seems like I was not thinking crazy. I will stick to the washer since it sees little to no force, and we already use that screw and washer in other parts of the build, so adding another type of screw will just increase the size of the BOM and not really give any benefit.
Thank you for...
Hello great knowledge of this forum. I have a simple question, where I work, we assemble stuff. We have 2 options with out product one with a 6-32 thru hole and one with a 10-32 thru hole. We use the same bracket for both parts that has a 6-32 threaded hole. Now the issue that has come up...
yup. that is what I was talking about. my thought is that the oxide coating will act as a protective layer/ lubricant for the threads. That is just my thought.
ok. now I have a question, if I used 18-8 black oxide screws, with 18-8 black oxide nuts, would that help reduce the problem? before they where uncoated screws.
Hello great knowledge of this form,
I have run into a interesting problem, and would like your input. For a project I am using 1/4"-20 18-8ss bolts that are connected to 18-8ss nylon insert lock nuts. The issue that has be seen is that sporadically the nut will lock up while I am trying to...
My guess would be condition A. If I was looking at the part, I would say that you would need a physical largest circle to make a fillet between the 3 circles. While with Condition A you have 2 arc that would have a radius between 2.54 and 3.55. That is just my thoughts. feel free to just...
Ok, thanks for all the information. It would be nice to be able to predict the angle that will happen. What can I say, collage has taught me to love equations. =). and charts, we like the charts
The application is the screw moves the plate for adjustment, I will have to look into acme threads or more higher-precision. I am trying to keep the cost down on the part.
I also take it, there really is not a equation or a chart I can referance to tell me the angle the metal will pivot to...
Hello all,
Is there a equation or reference that can state the orthogonal "twist" allowance of a screw through a hole depending on the material thickness? The picture hopfully helps. The material is .5" thick, and that is a m6 threaded rod with a m6x1.0-6h threaded hole.
Is there a chart or...
I am going to have to read up on a lot of this stuff. And yes KENAT I am US. ok, just thinking, if I just specify a parallel on one side and nothing on the datum side. theoretically the part can have a .5" bend, and if it is parallel with the datum within the tolerance, it is acceptable. so...
ok, I was incorrect on my understanding. GD&T is a little confusing. From what I have gathered, doing the flat with parallel will meet my needs. This pressure is too much =P
My company has been having some problems with our current sheet metal vender. when the piece came in, it was out of the old tolerance. luckily for the vender, since this was a prototype just to prove that, yes we can make the assembly, and yes it works (prove to management) we let it slide...
1) GT&D, looks like I had a dyslexic moment.
2) i was actually trying to figure out what would be better, straightness or parallel. For my application, a flatness would not work because it is a part that is in between 2 feed screws. and if I understand flatness correctly, that surface needs to...
Hello everyone,
I am still leaning GT&D. Can you look at my print for the straightness tolerance. I need this piece to be straight. As of right now I have the tolerance set on both sides of the piece, but I have a feeling I cant put a tolerance on a datum. Help please. Thank you for your...
