Metric dimensioning suffix
Metric dimensioning suffix
(OP)
I have a metric dimension: 20.0 h6
Now I remember back in sohool reading about all this stuff but I don't remember where the information is.
I need an explaination on these designations for both id and od, external and internal callouts.
Can anybody help?
Thanks in advance, pwest@miningservices.com

Just throwing this one out there for FYI...
H6 is for housing fits (bore ID's) +13/-0 for 20mm
h6 is for shaft fits (OD's) +0/-13 for 20mm

If you are going to be working much with limits and fits, you're probably going to want to buy the standard for the country you are working in and/or selling to. Besides the ISO 286 standard you saw in the link in ajack1's post, in the US you will want to have ANSI B4.1 and ANSI B4.2 for English and SI fits respectively. In the UK you will want to get BS 4500.
I believe that no matter what you are doing, if there is a relevant standard it's best to have it at hand.

Then you really don't want to reflect too long on the fact that the full designation is BS 4500:1969. :<}
