Tandy (English) Vs. Metric Snaps And Setters

[arbalest]

Is it OK to mix and match metric snaps/tools with english tools/snaps?

I've noticed in catalogs and on ebay the typical line 16, 20 and 24 snaps are close, but not exact in size to the typical metric sizes 10, 12.5 and 15mm snaps and setters.

I know that the snap sizes correspond to the size of the cap so there will be a small differences with respect to the cap and a concave anvil. But will the punch/setter/peening tools work out OK?

They should be the same size just two different methods for sizing.

Again, I think these sizes correspond to the caps rather than the fittings but they are not exactly the same:

The line 16 snaps are 3/8" which do match up well with 10 mm

But the line 20 snaps are 7/16" 11mm rather than the 12.5mm in the metric kits.

And the line 24 Snaps 9/16" which is 14.3mm rather than the 15 mm in metric kits.

Are you measuring or looking at the item description?

They should be the same.

If it happens they are different, the difference is minimal.

[arbalest]

I am using the descriptions - dimensions listed in my previous posting.

I see that the difference is minimal but I can't be sure that an eyelet or snap peening tool of one type will work effectively with the other. I guess I will just order a metric set of tools and find out if I can use my current stock of snaps.

I would have thought that a fraction of a millimeter either way would have no adverse effects in setting equivalent fastners.

[Tree Reaper]

Even if it is different .7mm is next to nothing and you would be dividing that by 2 so over all it's only .35mm on each side.

I would guess that these are all the same size and are made in the same China factory and given two different sizes, one metric and one imperial for the same item.
