Talk:Key (engineering)

blind features
I was reading this article and I was a little confused as to what was meant by "The keyseaters can also produce blind features." The internal link that is there didn't really clarify what it meant. If you could expand that idea, it would really help. Madjarv (talk) 21:37, 1 April 2010 (UTC)


 * I've revised the sentence. Let me know if it makes sense now. Wizard191 (talk) 22:36, 1 April 2010 (UTC)


 * The sentence is more clear and understandable now. However the internal link to blind still seems distracting. In my opinion it just seems like a definition of the word "blind" and doesn't really enhance the article by defining it in an engineering sense of the word. Madjarv (talk) 16:41, 7 April 2010 (UTC)


 * The Wiktionary entry does define the engineering sense of the word, so it is more than applicable. Wizard191 (talk) 17:39, 7 April 2010 (UTC)


 * Something may have changed with the Wiktionary article because the link on our page does not go to the specific part of the definition that applies. Said part also would not clarify the point for a layman seeking information. Alanthehat (talk) 17:48, 29 March 2014 (UTC)

ANSI/ASME Standards
I read somewhere that machine keys (at least square keys) are regulated by ANSI B17.1, however, I've also been getting ANSI B94.19 when doing some of the research, so I'm hesitant to put either reference into the article. Can someone with some more experience verify the standard? By the way, I was assuming keys for a torque-transmitting shaft. Ntlhui (talk) 18:59, 24 October 2012 (UTC)

Misleading, inaccurate, incomplete

 * The article has several problems. I am not clear whether round keys are mentioned, but I think neither axial nor radial round keys are mentioned. It is stated that all keys allow axial movement & are driving members, neither of these are always true, most modern keys are solely for alignment during assembly & are destroyed by relative movement of the parts or by torque being applied. There is a list of types of keys followed by descriptions of each type. The descriptions do not match the list. Several types are described under one subheading. There are mentions of keys being used to aid concentricity, as far as I know no keys are used for this. I am not sure, but I don't think that 'rotating parts' is part of the definition of 'key' Alanthehat (talk) 17:37, 29 March 2014 (UTC)


 * I have added 'may' twice in the lead section to (hopefully) clarify that not all keys either transmit torque or accept movement Alanthehat (talk) 18:05, 29 March 2014 (UTC)
