Avon Lifting Point Help

So I'm trying to make use of the lifting points in my avon. I wasn't sure what the little spots were with the plastic bolts in them but I suspected they were the lifting points and finally got two of them out today. And by God they are definitely for eye bolts. They are super beefy and go through the plywood into what looks like a thick steel threaded backer. But do you think I can find ANYTHING on the net about the specs of these lifting points? No.

So I'm going to use the two bolt plugs I got out to try and figure out the thread, and then I'm going to have to try to figure out how to get the other two out, since they just cracked apart when I tried to use a slotted screwdriver to get them out.

Anyone know how to get broken plastic bolts out of the machined holes?

Does anyone even use these lifting points?

Would have thought some release agent and a drill 3 sizes smaller than hole, ideally with a reverse bit and on reverse. Either it comes out as you drill but if its that brittle it will crumble out the thread once there is space.

There is an ap that let's you photo a thread and then line up with templates on the camera to find the thread.

buy a bolt extractor you drill down the middle of the bolt then turn in the extractor it tightens anti - clockwise various sizes they look like a tap but have a pig tail kind of thread to grip let me know if you don't know what they look like i will dig one out and send a pic.

cheers

Get a flat blade screwdriver slightly smaller than the diameter of the thread & twat knock it straight down the centre of the plastic, unscrew. Some times brute force & ignorance is the only way, fortunately I'm loaded with both😎


.....sh1t happens.......

I'm assuming it's a blind hole & got to come out upwards. So it'll need unscrewing. This is going to turn into a hole drilling thread if we're not careful

Okay guys thanks. I'll figure it out. Can't punch it through because the hole has a bottom. First thing I'm going to do is head to westmarine with one of the plugs and see if I can find an eyebolt with a big enough eye and a bolt diameter and thread that matches the plug. Then I'll cut the bolt off to the right length. If I can't find anything. I'll use pad eyes instead but it would be nice to use the reinforced threaded holes that Avon supplied. The strange part is that even with the plastic plugs screwed in, the hole is slightly larger around the bolt until it threaded into the stainless backer, so the plywood is exposed and visible and subject to water infiltration and possible rot. The deck hull doesn't feel soft by the lift points but it seems kind of dumb to supply them but not have them properly covered and protected from saltwater getting to the core.
