Coatings[edit]
Six different tanks for blackening? I only counted 4.
The discussion is oversimplified as it does not deal with typical protective coating processes such as anodizing for aluminum; ozide treatments for brass; passivation for stainless steels; conversion coatings (phosphate and oil), or mechanical plating, or galvanizing and electroplating of zinc, cadmium, nickel, and copper-nickel-chrome for steels.
On a side note[edit]
Based on all of the above I started the following discussion which might be of interest to those here: Wikipedia_talk:WikiProject_Metalworking#Heading_.28metalworking.29_and_upsetting.
Allen screw history?[edit]
When a search for "Allen screw" directed me here, I was disappointed to find only an example and description of same—nothing on its history. Who was Allen? Is he destined to vanish in the mists of time? But it's a 20th-century invention, right? Its origins can't be that obscure, can they? As you can see, I have many questions. (In the interest of full disclosure, I live in a small town.) – AndyFielding (talk) 10:22, 23 May 2021 (UTC)
- See Allen (brand) and also Allen key. Some of this information, or at least links to it, should perhaps be in this article. Either that or allen screw should redirect somewhere better. Lithopsian (talk) 19:19, 23 May 2021 (UTC)
Screws and bolts[edit]
Following on from discussions with another editor, I see two huge problems with this article. Neither are new and both have been discussed in the past, but not recently and never really resolved:
1. The article is titled Screw, a good WP:COMMONNAME. Unfortunately, a sizeable portion, not to say a majority, of the article is not about screws, but about bolts. Some of this is inevitable: it is hard to define a screw without mentioning what distinguishes it from a bolt, but the various tables and descriptions cover a whole bunch of things that aren't a screw by anyone's definition (eg. carriage bolts). So it seems there is a choice to be made: renamed the article; or gut it. Now would be a good time to voice opinions before I start anything formal or intrusive..
2. The definition of screw needs to be cleaned up. Again, you might say. The opening sentence of the article starts "A screw and a bolt ...", which should be a huge red flag. The existing article ties itself in huge knots by attempting to follow a fairly extreme definition of screw (which includes any bolt that isn't used with a nut), fostered by a particular interpretation of a very old reference book and some highly US-centric standards and legalistic (eg. customs and taxation) definitions (eg. [1]). A wider cleaner, definition might be good, but failing that either reword the existing definitions to be about screws or rename the article to cover both screws and bolts.
I'm aware that I'm opening a whole can of worms here. Read the archives for a great deal of background, even if most of it was a decade ago. There are some other articles that will inevitably need to be addressed, and could be considered to be part of the problem, whatever is done here: bolt (hardware), fastener, maybe threaded rod, etc.).
