Is the metal plated for corrosion resistance? What kind of plating?

It definately has some sort of corrosion protection. Not quite sure if it's a light zinc or what hut thry are not corroding at my house and I live on the water.

will these casters fit the origami 6 tier bookshelf?

I’m not familiar with the origami 6 tier book shelf. Are there holes in the bottom to accommodate the threaded studs? They are very nice wheels!

Can the 1 1/2 inch screw be replaced by a longer screw?

The 1 1/2'' screw is a stud that is form to the bracket of the caster.. Hope this helps.
