MG MGA - Floor Board Screws - Washer in Stainless?

I long since gave up on zinc plates unf screws to hold in the wooden floors, as they always rust. Stainless screws are the way to go.

Cup Washer part # - ACA5374

Moss is charging £0.60 each for zinc plated washers.
B&G is charging £0.60 each for S/S washers

What's the correct description for these, so I can hunt them down on eBay. As it's no longer "Cup Washer" as per the service parts list S.P.L?

several suppliers/manufacturers still list them as cup washer BW
Bob Walker

Also known as finish or finishing washers. Cheers - Dave

Alas not Dave, these are not the same as MGA and will dig into the wood.

Closest I can find on eBay is:

"flanged countersunk washer boat stainless"

100 for £8 plus postage but they are 5/32 size not 1/4, so ever so slightly bigger

Most marine stores have a great selection of stainless fasteners.

I may be mistaken, but I always knew these as "Tinnerman"
washers.

Many Thanks Edward.

Tinnerman or "Dimple" Washers seems to be the correct description to search eBay but alas I don't see them in stainless Steel.

I'll keep looking.

You can get nickle on brass, which will not rust....

When threading stainless and regular carbon steel together, always use an anti-seize lubricant to prevent the softer stainless from galling, FYI.

Good advice Del,

I certainly use a lot of copper slip these days.

Plus there is little load on bolts used to secure wood.
