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.

No source fo screws[edit]

A lot of the basic information is not sourced... CA148 (talk) 02:07, 9 October 2023 (UTC)[reply]

Screw heads are unlikely to milled and there are many different kinds of screw heads besides slotted[edit]

Before Tiny Particle edit:

 The screw has a head on one end that requires it to be turned with a tool.

After Tiny Particle edit on 19:10, 18 February 2024:

 The screw head on one end has a milled slot that commonly requires a tool to transfer the twisting force.

Tiny Particle's edit is wrong:

1. It is doubtful that the head of a modern screw is made with a milling process. Originally, the slot in a slotted screw was made with a file. Today most screw heads are probably made with a broaching process. Regardless, how the screw head is formed has nothing to do with the definition of a screw so it is not appropriate to describe a technique for forming a screw head at this point in the article.

2. There are a vast array of screw head types. Tiny Particle's edit implies that all screws have slotted heads. That is obviously wrong. Davefoc (talk) 02:11, 8 June 2024 (UTC)[reply]
