    316 SS machine screws - Passivated or not

    I ran a drill followed by a small diameter stainless rotary wire brush to clean out old sealant.  The holes cleaned up nice.  After the suggestions I am going to make sure I have multiple screwdrivers of the correct size to use just like iron worker spud wrenches. I'm keeping fingers crossed...

    316 SS machine screws - Passivated or not

    Nice job and thanks for the heads up.  Its going to be a PITA.  I wanted to ignore it since it didn't appear to be leaking - but knowing my luck as soon as it went offshore it would start to leak.     That's a beautiful work station that obviously took some serious planning.  The grab bars...

    316 SS machine screws - Passivated or not

    Confirms my thoughts - water, then beer and sandwiches, advil and cocktails, probably a gift card. Thankfully its the same rail going back in so it should fit.

    316 SS machine screws - Passivated or not

    I wish it would pre-bend.  When I removed it the dang thing went totally straight after having been curved since the 80's.

    316 SS machine screws - Passivated or not

    Does that citrus solvent cut through the polysulfide?  Never tried that before. I have a bunch of those west stirring sticks.  Also have plastic putty knives and plastic razor blades. Thanks for the suggestions.

    316 SS machine screws - Passivated or not

    I thought about that method.  I think that by the time I get one machine screw in place and tightened (just enough to maintain alignment) the rail will be pulled down so much that the donut will be smeared away from the next hole as it is bent into place.  I'm not confident that will maintain a...

    316 SS machine screws - Passivated or not

    Alex, I thought about Butyl tape and have used it in other applications.  I do like it, especially the cleanup aspect.  The problem I see is with this toe rail application.  The rail has to be slowly and forcefully bent into a curved position one bolt at a time.   The recommendations I have...

    316 SS machine screws - Passivated or not

    Thanks for the responses.  I like the Allen hex drive.  I'm leaning towards polysulfide for the extended working and cure time.  Thanks for the reminder on sealing the shoulder.  That should also add some limited separation/isolation between the aluminum and SS to reduce corrosion.   Taping...

    316 SS machine screws - Passivated or not

    Thanks for the info on passivation.  I doubt the old ones were passivated and I'm not sure they were even 316 but they appeared to be in relatively good shape.  Probably good quality stainless from days gone by. Slow cure sealant makes sense.   It will definitely take some time to refit the...

    316 SS machine screws - Passivated or not

    Throwing this out there to get some present day experience from the brain trust.  I am re bedding an 80's vintage aluminum toe rail and need to purchase a bunch of flat head machine screws.  It looks like I can order standard 316 SS flat head machine screws or passivated 316 SS.  Is the...
