Default FlyGuys DIY mashtun - any reason to not use zync plated washers?

hey guys!

well, i went out and got everything yesterday, went to put it together till i realized the washers didn't look like stainless steel. (and they weren't )
Went back out to a few different places, still couldn't find it, Create a bolt only had the 1/2" sized ones, didn't see any 5/8ths ones.
I Haven't read this anywhere of why you shouldn't use it. But, is there any reason to not use the zync plated ones?

I wouldn't do it. When different metals are in contact with each other, a process called galvanic corrosion exists. Eventually, the zinc will dissolve since it is the sacrificial anode. Look for stainless steel parts on the net if you can't find them locally.

For neutral water, zinc is not very soluble. However it is soluble in acidic solution like wort.

It is a normal item in river/sea water and sea food, etc, but in very low concentrations. I googled up rumors of zinc toxicity in humans, but found no definite concentrations mentioned. I'd avoid it.

Try Fastenal:

They will have SS washers, but I think you will be forced to buy a 10 pack IIRC.

i would deff head there, if i wasn't so impatient lol. i have it all sitting there and ready to roll, except for that damned washer.

and! zamal, i just called my local ACE hardware, they said they have a 5/8ths SS washer thats just a tad smaller then a normal fender washer, but is just as thick, so gonna go down after work and check it out. if that fails, i will be calling true value for sure

Thanks everyone!
