Stainless washers

[White Room]

Yeah, that's on eBay with free delivery.
The last ones I bought weren't as good as my normal ones I buy.

I have some those and I'm sure there not stainless....

Bought these the last time but the screw pulls through if your tightening them right up.

Never had a problem with the screws being pulled through, probably you being heavy handed Rob🙂

What did u drive the screws with some sort of industrial drill lol

Those last ones I posted are very soft with the screws.
I'm just getting to the last of them & wont buy them again.
