Author Topic:   Removing old snaps from hull

bradenton_whaler posted 03-03-2003 05:27 PM ET (US)
Has anyone had the pleasure of removing corroded/ rusted snaps from their hull? Mine are remaining from a spray dodger and the front cushions on an 24' O.R. Some of these have "snapped" off leaving a rusted screw w/o the head. Considering chisel, drilling hole, then patching with paste.... Any thoughts or shortcuts?
Thanks.

I take it these are screw snap studs? If so, they would have a phillips screw head inside the snap body that you should be able to carefully turn out (at least those that aren't already broken off). If they are riveted, just drill them out, probably with a 1/8" bit. As for those that are broken off, because I think the remaining screw might be too small to drill and use an easy-out, I'd try carefully making a small center-punched indent in the remaining portion of the screw with a sharpened center punch or scratch awl and a light hammer, so you can start a drill bit working, again about 1/8" or a little smaller, and try to drill the broken screw out, verry carefully and slowly. Once the metal is removed by whatever method, follow directions that have probably been articulated on the forum a dozen times or more, for repairing screw holes in fiberglass.

To remove the old screws cleanly go get a craftsman screw removal--these things work--it amazed me when it worked.

hi,
if they are the same as what was on my '67 16ft. they are riveted in. you have to drill them out. this will leave a small hole that needs to be filled and finished.
