good snaps (and bad snaps)

[Treesner]

additional research/ testing: 

amazon "Snap Fasteners 100% Stainless Steel Boat Marine Canvas Upholstery Snaps Cap" from northwest tarp. they are fasnap brand. emailed them for the longer post version.

good but not super strong holding

 

amazon "Fasnap Stainless Steel Snap Set, Marine Grade, 80 Piece:" says they're offered by northwest tarp but really they are fulfilled by someone else and they are actually DOT not fasnap 

these were a stronger hold and more so what I'm looking for. I tested and they work with snap brands, the part that makes them stiffer is the female socket. using the male on other brand female didn't improve strength. so I think technically I could stock up on the female version of the DOT brand and use with whatever other snaps I have.

some additional information from northwest tarp about the two brands

 

Fasnap brand is manufactured in Japan and DOT is made here in the USA.

Other than that they are high quality snaps and the only ones we sell.  One isn't really any better than the other though the DOT brand tend to have a higher gloss to them.  Fasnap are a little more dull.
