Pulled Snap - Easy Fix

Most of us have had a snap pull out of fiberglass leaving the hole too big to just screw it back in. Forget epoxy, this is far easier.

You need a replacement snap without a screw, a #6 rubber expansion nut that is long enough to go through the fiberglass and a #6 flat head machine screw long enough to go through the expansion nut.

Drill the hole out to the OD of the expansion nut. In this case it was 5/16Ē. Shove the expansion nut through the fiberglass. Put the snap on the machine screw and screw the machine screw into the expansion nut. Youíre done.

This is probably stronger than the original installation and Iím pretty sure itís waterproof.

I have a bunch of those in the garage. I used them for mounting west coast style mirrors on truck doors. They worked great and sealed the hole, the insert is brass and for 5/16 course thread. I never saw any small diameter sizes.

I think the biggest Iíve seen are 3/8Ē and the smallest #6. I sold them in my marine store and I got the one in my photos from my neighborhood hardware store.

I take a short piece of tie wrap, fold it half, insert into existing snap hole with two little ends of the tie wrap sticking out, screw the snap back in carefully and the two sides sticking out will be hidden by the hollow of the back of the snap.

Be careful starting the screw so the tie wrap does'nt get pushed into the hole.

I usually apply a little bit of caulking under snaps to keep water out and that also helps hold the snap.

Most screw anchors require drilling a bigger hole which I like to avoid.

Parks,


Great tip, I've never used those expansion nuts, looks like they have a rubber coating?


Do you secure the nut prior to putting the bolt in?


I've used a lot of Rivnuts over the years and have the tools for mounting.... suspect they would work pretty well, too.



Another trick for holes too big is to simply put a toothpick in the hole as you screw in the screw. It wouldn't be the thing if you needed to remove it occasionally, but will work pretty well.



But I like your ideal better.

Seevee, the expansion nut, also called a Wellnut, is made of a rubber like material and has a brass nut molded into it. You just shove it through the hole and run the screw in. As you tighten the screw, the molded in nut pulls the rubber in and causes it to expand. They will also work pretty good in material that they can’t go all the way through.

Parks you’ve always been a great source of knowledge over many many years and still continue. If you get tired of retirement your store could use you.

Nice to know the Wellnut” is available. but to me, a bigger problem is how to deal with the snap or Lift the Dot stud that breaks off leaving screw without a head buried in wood or fiberglass. Anyone have any tricks to deal with a broken screw left in fiberglass or wood?

Can’t really just move to a slightly different place because there is the female snap or Lift The Dot still on the canvas that is looking for its male counterpart when snapping the canvas back on.

Somehow I deleted my comment, so here’s a repeat.

It’s great to know the threaded plug is available. But the more difficult problem is what to do when a canvas snap or Lift The Dot stud breaks off and the screw remains buried in either wood or fiberglass. Anyone have any tricks removing the screw? It’s too small for use of an easy out, and I don’t want to remove material around the embedded screw to try to get a pair of needle nose pliers on it.

Any ideas would be great cause I have a few Lift The Dot studs in my fiberglass hull I would like to remove to be able to replace with new ones.

Thanks Fish. I was in the store last week. Thought they were doing a pretty good job except the inventory was a little low. Itís really hard to sell what isnít on the shelf. The girls hugged me when they saw me. It was nice to know they miss me.
