Metric Thread clearances?
Metric Thread clearances?
(OP)
I am designing some equipment that uses some special sized metric threads (103mm). I want the two mating pieces to turn freely by hand (jam nut, adjusting nut, etc). Is there any documentation that defines which tolerance and grade to use when you want a specific outcome (like hole/pin fit tolerances)? I am guessing I want to specify a tolerance/grade for the nut of "6H" and the matching bolt "6g". I believe the standard fit tolerance will work in my situation. I just wasn't sure if I should go larger "6G6g"? I don't want to loose a fit either. Suggestions?
Thanks
Bill

You will find out among other things that a combination of 6H/6h is never used - and for a good reason. You use 6H/4h or 6H/6g. Also why are you going with M103 x 2 ? M102 x 2 and M105 x 2 are standard. Have your company order a booklet for DIN13 in English from:http://w

Still having a problem. It looks like they are working on it and the web site should be available shortly. If not google : Beuth- Verlag - English.
