    Are any exterior screws completely rust free?

    Banned
    tried a few over the years in my double glazing edging and within a year need replacing as completely rusty due to living on a beach.

    Have tried the expensive ones that state rust free but even these rust

    cheers

    How about if you painted them in clear laquer (sp)

    I think thats one of the downsides to living near a beach maybe you could get some plastic covers for them, small price to pay for such a great view, I wouldnt mind swapping with you:thumbsup: you wont have that problem here:-D

    Are screws absolutley necessary-there are a wide range of adhesives available.

    Search eBay for "stainless steel screw" and see what is suitable.[/QUOTE

    Low grade SS will still rust under those conditions though probably, high grade SS is what's needed but it's whether it's economically viable which is important.

    cover it in silicone sealent

    Thanks all but already used stainless steel screws and they barely last a year. I do cover them with vaseline and encase in a plastic cover (ooh err!).

    Maybe I shouldnt cover with vaseline!

    Will look out for some marine grade screws thanks

    thanks - is there an alternative name for these types as cannot find them on toolstation.com

    Brass screws dont rust - they can't

    just cover with the plastic screw covers for colour match

    A4 is marine grade S/S

    Sea air is very corrosive even stainless steel is not totally resistant. Are they rusting - orange deposit - or dissimilar metal corrosion - usually white/grey deposit?
    Most screws are coated for protection but get damaged when screwed home and subsequently corrode.
    Brass might be the answer to rust but may react with other metals.

    Hi,
    If you are looking for marine rade stainless steel screws, why not visit your local ships chandlers?
    Any boating shop will have a stock, whether they are the right ones for you is another matter, but they will be able to point you in the right dirrection!

    The effect you are finding is called bi-metal corrosion, It is caused by 2 metals ( aluminium and Stainless steel ) coming into contact and is made worse by the sea air,

    Have you tried Kurust to remove the rust?

    isnt one near me and I only need 12 screws. Just fed up with having to replace them every year and them staining the UPVC.

    there wouldnt be any screws left if I removed the rust :w00t:

    Maybe put a few beads of silicon sealant over the new screws to create a waterseal.

    Is it the main frame fixing screws( large head) or the hinge fixings ( small gold/brass colour), also are all the screws rusting or just the ones on the bottom?
    Double glazing "leaks" ie some water passes the seal between glass and frame and exits via drainage holes.
    DG frames usually have galvanised reinforcement built into them, open a sash and look for some small brass type screws around the inner frame that don't appear to do/hold anything. If you have these, then you you may have corrosion brought on by electrolysis, galv, steel, etc and salt water.
    Have you asked the original window supplier or any other in the area as they will have the same problem and should have a solution.
