Default Wire Terminal Screws on Receptacles

Would anyone be able to tell me the composition of the wire terminal screws on receptacles? They are magnetic so are they steel? Also, what would happen if they were zinc (electro plated) screws?

Happy weekend,
Rey

So, what does this have to do with the price of tea in China?

@Bird dog and tjb, your comments are not helpful so why respond? Do you have nothing better to do than to troll? If you have nothing helpful to add, please do not respond.

You could have googled this. Why does this really matter except MUK (More Useless Knowledge)?

I did google it and nothing is coming up...so I thought I would check here. After all this site is called "Electrician Talk". This is my point of asking...DOES IT MATTER?????? What the screw is made of????? If you replace the screw that is on there with a zinc (galvanized) screw is there potential for unwanted effects?

The other times I've had questions as my history shows, someone like you - the "Senior", members reply with unhelpful, rude comments that add nothing. Again, if you have nothing helpful to add, then please do not comment. This is a legitimate question...

Well that was better. No it doesn't matter if you have to replace it. However, usually it's easier to just replace the receptacle. The screws are designed not to back out all the way. If you get it out, you may not get another one to screw in.
btw those screws are special. IIRC they are called binding post screws.

This is an odd question but then again if you haven't been around much yet, is it. Bird Dog has it right. Go play with a receptacle and take out a screw, now try to put it back in.
For the buck, replace the receptacle.

That is the way forums work and the best thing you can do would be to ignore those post and wait for an answer.

Curious did you withdraw a screw and test it?

Or, did you have a magnetic tip that sticks to a screw?

Myself I have never given this any thought but if the screws are magnetic I would assume they are coated.

Before you get all indignant, maybe you should check yourself, son. The terminal screws on duplex receptacles are NOT magnetic, so they're not steel (Unless they're from China). Zinc plated screws would be a dissimilar metal to copper, and/or aluminum, and would cause a galvanic effect on the termination. That's why they're NOT zinc plated.

I usually get blamed for that. It's refreshing to see @Bird dog catching the blame this time

Googled and one manufacturer says that they are.

size 8 plated steel terminal screws and size 8 hex plated steel green chromate ground screw.

Some of the higher quality ones may have stainless screws. Low quality stainless can still be magnetic.

Like most of the other people here i haven't really thought about the material and if i have a problem that requires another screw then i just change out the receptacle

pass & seymour receptacle had the screw material list in there specs

They’re not magnetic until they’ve been magnetized. Until then, they’re only ferromagnetic, meaning they are attracted by magnets but don’t attract other ferromagnetic things on their own.

C’mon, everybody knows that!

Replacing the screw would void the listing and labeling as it was assembled in a factory recognized by a NRTL.

So if you do this Vladimir Putin will hunt you down (and he will find you) and strap you naked to a horse and ship you to the gulag in Siberia.

Now its' really cold there, so right about the time your eyeballs freeze and crack like little eggs, you're gonna wish you went to Home Despot and spent .99 cent on a damn receptacle.

I was having an identity crisis. It's good to know I'm a troll and not an ogre like Shrek. Well thought out questions help too.
