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. Failing that, you need a fabrication drawing with dimensions and tolerances. I figure that a clerical level person should able to is your parts list and order the parts on it such that you can assemble the system and it will work.
This drives the quality of information on your parts list. I Googled “Standard Metric Keys” and the first hit I got told me that for a 75mm diameter shaft isk “standard key size” is 22mm wide x 14mm high. That is different from 20 x 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.
But that still means a single unambiguous drawing of the thing exists and isoo are just making a distinction between “here is the drawing” and “here is where to go to look up the drawing”.
One of those has to be supplied though. One of the problems with “standards” is that there are so many of them – often for the same thing – and they are rarely all the same. To fully and unambiguously define a rectilinear key you need: Width Height Length Material Hardness Finish plating It is not clear to me from your two prior posts that you accomplished that. It is not clear from your second post what may be included in the “certain companies number”. Very often keystock 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.

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. The way to avoid this – or similar mistakes – in the future is to always provide complete and unambiguous information. Or to say it another way – answer every iao question about the part before it can be asked. Quote MintJulep One of the problems with “standards” is that there are so many of them – often for the same thing – and they are rarely all the same.
I don’t have either standard. For example, in terms of tolerances products manufactured to B There is no interchangeability isk B Regarding unambigous key designation, according to the ANSI a key shall be designated by the following data: As for material of a key, all three standards state that: Hardened keys shall be alloy steel through hardened to a Vickers hardness of to HV. When other materials and properties are required, these shall be as agreed upon by the supplier and customer.
And there is one more thing to be mentioned: In terms isso 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. These characteristics have to be somehow controlled to make everything working properly. What is even worse, some dimensions given in the standards, like depth of a keyway in shaft t1 and housing t2 are nonverifiable.
