Most of my threaded inserts have failed. It started from day-1 when my originally dead-on-arrival new PBP arrived back from warranty service for a dead screen. I think the screws were torqued too much, which stressed the plastic supports for the inserts.
It became critical when the hinges failed. I've painstakingly used JB Weld to rebuild the supports and bond the inserts back. The trick is to wait for the JB Weld to set well but still be flexible enough to make any final alignment adjustments with the screws in place. I put the screws barely threaded in place from the with a dab on oil on the threads--threaded just enough to use the screws as alignment tools when the JB Weld has set to a firm but still somewhat flexible consistency.
It's a tough and tedious job and it required re-doing a few of the inserts for better alignment. I rework and prepare the plastic with a Dremel tool and several tiny carbide bits.
