The clips under my kitchen sink are terrible. It's impossible to get them tight, and as result it's hard to keep the top caulked, and I now have water damage. The clips in question were from a Realtor special renovation, and look like:

Top mount sink clip screw cheap

The head goes into a track that's part of the sink: enter image description here

I think it's called a U-Channel sink.

The problems include that the bottom screwdriver slot strips, the screws are hard to turn, and the tighter you get them the more the entire thing wants to tilt away from vertical. I've tried to get this right a half dozen times, and the best I do is get half the clips to actually bite.

  • which part of the clip is supposed to engage with the benchtop? maybe screw some shallow metal L channel to underside of the benchtop to hook that little toe into, – Jasen Sep 15 '19 at 5:40
  • How easily does it move inside the track before you start tightening? If it doesn't move freely you might need another set with a smaller head, you could try the ones Home Depot sells from Elkay sink company. – aofkj Sep 15 '19 at 11:34
  • Did you put something under the sink rim to seal it? This will also help hold it in place. If you use Adhesive Caulk it will be strong, maybe too strong and you will damage the counter if you ever need to remove the sink. Some people will recommend plumber's putty, but it can dry and crack over time. – Mattman944 Sep 15 '19 at 18:04
  • looks like the counter top is too thick for those clips/screws. I rigged one in an old apartment i had with 4 small cheap fake vice-grips from harbor fright. – dandavis Sep 16 '19 at 5:23
  • The screws are only mid way engaged with the countertop, so not too thick. The pointy tip of the black metal is supposed to dig into the countertop bottom, but generally fails to. The sink had silicon caulk, replacing plumbers putty which had failed. The silicon is now failed. – Bryce Sep 16 '19 at 6:03
