Thread: Rub rail screws

  1. #1

    Rub rail screws

    Anyone have any idea what size screws are used to hold the stainless rub rail in place? I need to replace a bunch of them. Not near the boat to figure it out myself

    Mine had 1 1/4” #8 square drive counter sunk screws. The original are monel not stainless. I replaced with 1 1/2” of the same quality.

    Looking for the monel. Tough to find. You said yours were countersunk? Do you don’t have the stainless rubrail?

    It is a stainless rub rail. I meant flush head. Oops

    Jim, using the same diameter screw is fine if it still holds well, but on my boat when I removed the SS
    rub rail I found that the #8 screws went in much too easy so I replaced them with #10. I believe that
    Steve at SAM'S can get you monel screws or use 316L SS (American made). Lots of import 316 is crap
    and you shouldn't waste your money on them. Pay a little more up front and you only need to do it once,
    otherwise you will be buying new screws again after you realize you've been screwed by poor quality.

    If you can't get them from Sam's try Mcmaster-Carr. I have bought some of their 316SS items over the years and they are holding up fine.

    The next rub rail problem..... on mine, several of the screw heads have broken off leaving the shaft of the screw buried. Any good tips on extracting other than a smaller drill and extractor? Tough to keep the skinny drill bit parked on the broken stub.

    remove the rubrail, dig around the screw enough to get a pair of needle nose vicegrips on the screw, most of the time they come out easy. unscrew then replace the rubrail and it will hide the area that you dug out to get to the screw

    I need to replace a few of these on my rub rail and swim platform rub rail. A few are protruding from the rail and are actually bent, not broken. I would think if I replace these with SS, they's snap instead of bending, so it would seem the originals would be a better choice.

    Has anyone found a source for chrome plated monel screws? If not, would silicone bronze be a good substitute?
