Just a question in regard to fixe triplex bolts. One of the big advantages is the they are supposed to be easily removable.
However I've noticed there are 2 ways of placing them, which I think would effect the removability and/or strength of the bolt.
First: Terminology - I'm going to use the words stud (the threaded bit with the cone on the end), sleeve (the hollow thing with the shoulder on the end), nut and hanger.
The way Fixe say to do it is to put the hanger over the sleeve (ie put the hanger against the rock, put the whole bolt through it and tighten). This uses a 12mm hanger, and when you want to remove the bolt, you take the nut off, hammer the stud in then pull on the hanger to pull the sleeve off the stud.
The way most pictures on the internet show it, they put the hanger between the sleeve and the nut (a 10mm hanger that sit on the threaded bit of stud). This would make the hanger useless in removing the bolt, and you'd need pliers or similar to grab the edge of the sleeve. Similar to this pic (no sleeve sticking through the hanger):
My thought is that if the hanger is on the sleeve (as fixe show), would that lower it's pull-out strength (particularly in tension), because there'd be no "self-tightening" effect of the stud being pulled into the sleeve. Maybe I'm way off track with this though?
