Chair leg bolt holder keeps coming out, how to best glue?
I'm not sure, despite trying to find the terminology on several sites, exactly what the term is for the part I'm having a problem with. So I attached a photo of the leg assembly (from the top as the chair is upside-down for repair, first photo) and a detail of the bolt holders on the leg (second photo). Looking for the correct name (and method of immobilizing) what the inner bolt screws into. Closest term I've seen is "threaded insert."
The chair I have has a non-tapered bolt that screws into a bolt holder (threaded insert?) on the chair leg, and one of them keeps backing out despite having tried using wood glue before.
It's a wider threaded bolt itself, screws in with a 6mm allen wrench, then, when it's seated, I can screw in the bolt that keeps the leg attached.
It's driving me crazy because it needs fussing every 2-4 days and I worry I'm going to miss one of the times it needs repair and damage the chair.
Should I be using epoxy for this? Or?
