Earthing of metal boxes

I've never thought about it but we call them socket screws too!

Interesting. To me, "socket screw" implies that it has a head with a female socket (e.g. for an Allen key).

We call those socket cap screws!

We call those socket cap screws!

Fair enough, but I usually see that abbreviated to just "socket screw"

Different things frequently have the same name.

It is a screw which holds the socket in place.

What else would they be called?

 

[Echo the husky]

Plate screws.

 

[JohnD]

I might say Faceplate screw

this is a Socket cap screw, or socket headed screw. Smaller ones are more likely to be splined

Or socket button head, very popular on bikes

Plate screws.

I always thought a plate was for food.

 

[Echo the husky]

AAAAAAAAHHHHHHHHHH!!!!

 

[EFLImpudence]

Precisely.

Indeed - but it seems that this is a case of the opposite - the same thing having different names ....

Oh, I see, is that where the "socket" (of "socket screw") comes from?! (I confess that I hadn't thought of that possibility!) If so, do you also recognise "switch screws", "FCU screws" etc. ?

... and, FWIW, that's definitely what I would call them.

By definition, obviously.

Have you been taking some winston pills?



There are even machine screws for holding machines together.

 

[EFLImpudence]

A real misnomer is self-tapping screws.

 

[JohnD]

coach screws for holding coaches together

countersunk screws for holding... um... counter sinks.

Indeed there are. I have a suspicion that all the things we've been talking about (fully threaded and designed to go into threaded holes, rather than to 'screw' into materials like would) may be classed as 'machine screws'. A more interesting (and probably less well understood) distinction is between a machine screw and a bolt (intended to be used with a nut). IIRC, a bolt is not fully threaded, whereas a machine screw is - but I may well be wrong in that recollection!
