In layman terms, what is “engineering”? Width Height Length Material Hardness Finish plating It is not clear to me from your two prior posts that you accomplished that. This drives the quality of information on your parts list. Failing that, you need a fabrication drawing with dimensions and tolerances. Quantity must be a positive whole number.

It’s easy to join and it’s free. Very often ixo is sold in some arbitrarily long length – a foot, or a yard, or a meter – with individual keys cut to length from that stock by the user.
Or, in more precise terms: SCOPE This standard presents metric dimensions, tolerances, sizes and fits for straight bores, tapered bores, keys and keyways for unmounted industrial flexible couplings. Thank you for helping keep Eng-Tips Forums free from inappropriate posts. One of the problems with “standards” is ios there are so many of them – often for the same thing – and they are rarely all the same.
One of those ido to be supplied though. Perhaps if the size, shape, tolerance, material and finish of the key was given on a specific “standard” and that specific standard was quoted when the key was specified, then no problem.

That is different from 20 x These characteristics have to be somehow controlled to make everything working properly.
It seems very possible to me that you did not provide a complete and unambiguous definition that allowed whoever chastised you to buy or make the key. Close this window and log in. The intent of this document is to offer designers and users of flexible couplings preferred dimensions, tolerances and fits for metric bores and keyways. At the time of publication, the edition indicated was valid. Bores are to be measured prior to cutting the keyway.
Inspection methods for straight and tapered bores and keyways are included in the annexes. The keys and keyways followed the recommendations of ISO R When other materials and properties are required, these shall be as agreed upon by the supplier and customer.
Hardened ido shall be alloy steel through hardened to a Vickers hardness of to HV. Or to say it another way – answer every possible question about the part before it can be asked. I Googled “Standard Metric Keys” and the first hit I got told me that for a 75mm diameter shaft the “standard key size” is 22mm wide x 14mm high. If not then the people who told you you didn’t know what you were talking about – while perhaps being a tad harsh – did possibly have a point.
Exceptions This standard d773 not apply to: Posting Guidelines Promoting, selling, recruiting, coursework and thesis posting is forbidden.
I don’t have either standard. Did you reference some kind of standard or document for this “standard metric key 20 x 12 for a 75mm dia. We are not even going into tapered, low profile, woodruff, etc. The way to avoid this – or similar mistakes – in the future is to always provide complete and unambiguous information.
I figure that a clerical level person should able to take your parts list and order the parts on it such that you can assemble the system and it will work. In terms of dimensioning and tolerancing of keys and keyways the standards focus solely on aspect of size of features, without paying any attention to other important geometric characteristics, like orientation and location of a keyway relative to axis of shaft and housing.
