Talk:Nut (hardware)

DoD / MoD witticism (2004)

"Hexaform Rotary Surface Compression Unit" is not a valid term, 210.142.29.125. Duk 13:56, 15 Sep 2004 (UTC)

Expand please (2005)

Need also explanations (or links thereto) of "prevailing torque nut" and "pal nut." Could also use an explanation of nut markings (like, WTF does the F on the rim mean? or little rectangles on the facets—some breed of interference nut?) Kwantus 19:51, 2005 May 27 (UTC)

Nut classes

there was some mixing of SAE and ISO fastener grades that I've removed, for example Grade 8 is an SAE grade, while Grade 8.8 is an ISO metric grade (i think) that is totally different. Anyway see [1] and [2] --Duk 19:13, 26 October 2005 (UTC)

I was wrong, sorry; metric nut grades are different from their respective bolt grade - the right hand digit and decimal point are omitted. Whereas SAE nut and bolt grades are the same. --Duk 21:41, 26 October 2005 (UTC)

Your second comment is correct. I'll reinstate my previous, correct sentence, because there's no reason to duplicate a table here instead of just providing a wikilink to it, which I was going to provide at "proof strength" in my previous sentence. I can also add an additional short sentence. This will be a much simpler solution, to avoid duplication and keep the page concise. --Simian, 2005-10-27, 01:01 Z

Sounds good --Duk 01:17, 27 October 2005 (UTC)

FAR EASTERN MANUFACTURERS refer to metric nuts by class, the Eurpean market refers to them by grade ie class 8 is grade 8. in practice class 6 are supplied into Europe marked 8 this unusuall situation does not appear to be an issue and the failure of class 6 nuts on 8.8 bolts again does not appear to be an issue! —The preceding unsigned comment was added by 80.175.213.17 (talk • contribs).

Nylock

What's with the picture caption that calls the nut with the nylon insert "not nylock"? If that isn't a nyloc/nylock, then what actually is? 68.0.226.163 03:24, 6 February 2007 (UTC)

That's probably somebody reacting to "Nylock" probably being somebody's trademark. This deserves some investigation and editing.

Nylok is a trademark of the Nylok corporation and are produced to the German standards Din985 and 982 again the popular class is 6 to go with 8.8 bolts! —The preceding unsigned comment was added by 80.175.213.17 (talk • contribs).

Merge in other nut pages?

It might be better to combine the other pages about various kind s and uses of nut into this main page: [Castellated_nut], [Locknut], [Nyloc nut] et al are currently very short stub articles and although these are interesting pieces of hardware perhaps do not deserve their own encyclopedia entries.

Combining the pages would also make it easier to produce a coherent structure for the resulting nut page, although with the present situation that might be thought of as wishful thinking.

• Weak support -- Sounds like a good idea to me but I guess I'd want to know the complete list of articles to be merged to here. -- Atlant 13:25, 2 May 2007 (UTC)
• Support. Even if one or two kept their own articles because they had enough info to do so, most of those could just be defined here. I would do it, and add photos, but currently lack time and inclination to bother. However, it is a good idea for the future. — ¾-10 03:00, 6 November 2008 (UTC)

Nut vs grommet

Dear all. My mothertongue is not English. What's the difference between a nut (hardware) and a grommet? Aren't these things in some cases interchangeable? Thanks. 84.198.123.112 (talk) 23:51, 4 November 2008 (UTC)

The word grommet usually refers to a ring that reinforces an eye (hole) in a sheet of fabric. Main article grommet explains it. Usually tarpaulins and sails have grommets along their edges. As far as interchangeability of the words or objects, nut (hardware) and grommet, I cannot think of an example of such. The closest I can think of would be that some flange nuts have very wide flanges, essentially being a nut with its own built-in fender washer, and that these accomplish an analogous purpose to a grommet in that both distribute the forces to the substrate. The grommet keeps the eye in the fabric from ripping, and the flange nut keeps, for example, a sheet metal substrate from ripping or bending. — ¾-10 02:56, 6 November 2008 (UTC)

I think I've seen grommets which are assembled with two flared collars (rings, donuts) which screw together (instead of the more typical compression or deformation fastening). In this case the female threaded side could (I suppose) be called the "nut" while the male threaded side (threads on the outside) would not be called a "screw". ... I think.40.142.187.175 (talk) 01:02, 21 August 2017 (UTC)

Is this a nut?

I'm wondering what this thing is if not a nut: A relatively large diameter ring, threaded on the outside, as might be used to hold a window against an o-ring into a flanged hole etc. I've always called these things nuts, I suspect incorrectly, which is why I'm here. If it is a nut then it doesn't fit with the definition at the start of the article.--122.57.98.217 (talk) 14:17, 15 April 2009 (UTC)

If its threaded on the OD then I'm going to say it's probably not a nut, but you might be able to find a reference that says otherwise. If so we can modify this article. Wizard191 (talk) 16:11, 15 April 2009 (UTC)

Adhesives

It is true that there are a variety of specialty adhesives used for thread locking. Anaerobic adhesives, mainly. The problem I have (as an ex-Loctite product development guy) is that many regular adhesives can also almost as easily be used, especially those that cure (rather than simply "dry"). I'd go so far as to say that MOST adhesives can improve thread locking "stamina" (performance, vibration resistance, resistance to movement). In fact, even mastics which do NOT dry can serve this purpose in certain applications. "Specialty Adhesives" is too restrictive, imho. — Preceding unsigned comment added by 40.142.187.175 (talk) 01:09, 21 August 2017 (UTC)

History

I think this article would benefit from a history section - but I am nowhere near able to write it. I came here looking for it because of this picture [3] (it's from a facebook post about renovation of a farmhouse from 1866, presumably in USA, and I believe it shows two large gear-like nuts - shaped pretty much like the hole in a modern Torx screw - used to tighten a stairwell construction.)
