I bought a sheet of this stuff in 1/4" to make a couple backing plates out of and was thinking of bedding two pieces on my transom (after grinding to bare glass) with tapped holes for my volvo trim tabs so I wouldnt have to through bolt and deal with the core for all the holes.
Never even seen it but I drilled and tapped a hole for a 1/4-20 plain steel bolt I had in the shop and thought I might try a little destructive testing. Couldnt even come close to pulling it out with a hammer so I put the bolt in the vise. First bolt broke (and bounced down behind the bench) so I did it again and it pulled out of the glass with a slight fracture around the hole which was very close to the edge. I have to say that I cant imagine how many pounds of force would be needed to pull a bolt straight out of this stuff. Probably several hundred.
What is anyone using this for? It certainly holds a bolt.
