I went back and checked my snaps with a magnet. The $13 giant snaps will not pick up the tiny magnet. The $8 ones do. The tiny ones from Brownies, like for backup lights and long hoses, have no magnetism at all. By the way, I was testing snaps that I have in a collection that are not on my gear. The ones on my gear are very old and I got them from a yacht suplly store which is no longer in business, and they were unable to order the ones I wanted as of about seven years ago. I try every one I see trying to find the best ones. So far some are from Brownies, some from a hardware store in Lauderdale by the Sea. I always check the stuff out of habit due ot the scooter building. I frequently get bullshit stainless snuck in on me, and just take it back for replacement. Washers are a big one for this type of corner-cutting. It is funny how the smallest detail of dive gear can make or break your fun. To test this stuff otherwise I hang it off the dock on a line for a few days. The bottom line is that the more the snap attracts money and the less it attracts magnets the better it is at not rusting. Springs are the same. houdini@gr*.xt*.ne* wrote: > > Scott Landon wrote: > > > > unfortuneately, there are quite a few grades of stainless. and as you can > > guess, some grades cost more than others. i am by no means a metallurgist, > > but i have installed my share of piping in corrosive service in a chemical > > plant. a 316 grade would be ideal. > > > > scott > > > > >From: Mike Rodriguez <mikey@ma*.co*> > > >To: Art Greenberg <artg@ec*.ne*> > > >CC: Cavers <cavers@ca*.co*>, Techdiver <techdiver@aquanaut.com> > > >Subject: Re: Stainless Steel Bolt Snaps > > >Date: Sat, 03 Jul 1999 19:09:25 -0400 > > > > > >At 08:08 AM 7/3/99 -0400, Art Greenberg wrote: > > > > > > >I've just replaced another large SS bolt snap on my rig.
