    I'm going to mounting a 3 basin sink and a hand washing sink to sheet metal.

    On top of that I can only access one side of the metal. In other words I can't reach around the backside and screw a nut on.

    I'm thinking of using angle brackets and just mount the sink to them. This way I can easily work on and remove it for repair later on.

    But to actually attach to the sheet metal I'm thinking either self-tapping screws or anchor bolts.

    What are your thoughts?

    Thanks

    Never seen those before. I'm guessing when I screw into them they pull in/compress/flatten like a rivet....yes?

    Thanks

    Poprivets? Hard to say without seeing what you are trying to do.

    use liquid nails on the underside of the sink lip so when you drop it into the hole and press down you get a solid seal on all 4 sides. put a thick towel in the sink and then set a cinderblock or something heavy in it overnight.

    Self tapping screws are ok for some stuff but I don't think I'd use it to hold a lot of weight, the nuts in the above post looks neat but I've never seen them either.

    They actually use a special rivet gun. This is the harbor freight version, it is good for a project or two...but like most of the cheap tools they sell would not be recommended for someone using one on a regular basis.

    Harbor Freight and I are not on the best terms right now since the fault hub on their trailer got me into an accident yesterday. Then the manager got snotty when I called about their 90 day warranty....said it was my fault when the bolts were clearly shredded in the exact same place on all of them.

    I appreciate the suggestion though. I'm sure Lowes has something similar.

    Absolutely, I was showing the bottom wrung of pricing. I have my local Snap On man's number in my cell phone. I highly recommend buying good tools, but understand that for a one time use it might be worth taking a gamble on chinese crap.

    Two rules to live by...

    Cry once, it generally costs more to redo than it does to do once correctly.

    You may not always get what you pay for, but you always pay for what you get.

    Run a bead of clear 100% silicone around the edge.
    Put a 5 gallon bucket of water in the sing overnight.

    That is the way we have been doing self rimming sinks on granite tops for years.

    Takes 5 minutes. It isn't going ANYWHERE unless you want it to.

    How about toggle bolts? Other than that, the best thing to do is get some backing behind the metal. I wouldn't trust self tappers for that weight. Maybe some sort of kicker to the wall or floor also.

    we need a pic of this sink, preferably the underside so we can see what sort of lip/flange it has.

    a pic of the counter top probably wouldn't hurt either.
