Default T-Top mounting screws loose...

I have 2 loose screws loose that will not tighten anymore in the front port and starboard base of my T-top. Any suggestions on getting something in those holes to make these screws tighten would be great. I have tried some 5200 in the hole and on the screw but it is very hard to get it in the hole. The T-top is not loose at all but I would feel better to have all the screws tight as I do a lot of ocean fishing and the boat takes a lot of rough riding. Thanks, Robert.

a quick short-term fix is to insert a small length of heavy mono into the hole with the screw, and tighten down...the screw will "grab" the mono and pull itself tight

not sure why you can't get the 5200 in there...have you tried a syringe?

Now that you have 2 screws loose it's only a matter of time before the rest are loose.
It needs to be thru bolted any way you can do that. There are several ways, but it needs to be done.

Of course you would have thru bolted if it was feasible and if your deck is failing you may have to find a way to make it happen. For now though I offer a variation of cgrand's technique that I have used on many occasions for what have proven to be permanent fixes. Widdle a plug of marine grade wood to a length as long as the deck is thick and press it into the hole. Then run the screw back in being careful to get the screw started betweed the plug and the edge of the old hole not to push the plug thru. If your deck is not rotten the screw will bite and hold. And I always coat the screw threads with 5200 and squirt as much in the hole as I can.

I have use plastic anchors coated inside and out with 5200. But you can also clean the loose crup out this a drill bit and air hole prior to filling them with epoxy, then push a thredded short rod or short ss anchor into the hole, leaving enough thread above the base ,to put a nut on and tighten after she has dried.

5200 is not ideal for holding screws for your t-top. Get a drill bit a few sizes bigger than what you have now. Drill out all 5200. Maybe get a small round file to clean the hole. Go and find some open cell foam. Get some West System epoxy. Mix the epoxy take a small brush and brush the epoxy around the wall of the holes. Cut the foam to blocks that are larger than the holes. Soak the foam in epoxy and stuff it down the holes(make sure you go down deeper than the deck). Let this cure over night.

After it cures, get a drill bit a size down and drill the middle of the hole half way down the foamed hole. Mix more epoxy and add some filler to it. Get it to a good paste. Get a syrengy and shoot some of the epoxy goop till it over flows. Level it off and let it cure.

After it cures, drill the hole you need for your screws, and put the T-top back.Now get the screws and give em a good wash with alcohol. coate it with epoxy and screw in your t-top. I would do this with all the t-top screws when I'm doing it.

A good trick with 5200 is to heat it before you use it. When I need to get 5200 into a small hole I use a hair dryer to heat the tube. The caulk becomes thinner and flows better. If I can't get to the hole with the caulk tube then I heat some on an index card and use a tooth pick to coat the inside of the hole before I screw. This should be SOP for all below the water line holes and fittings.

Get your self some SS toggle bolts, West Marine has the good ones, If there is foam under the deck you can use an allen wrench in a drill motor to get enough clearance for the toggle bolt to make its 90 degree turn , Ken
