Wood strips over time so you really have a limited number of installation/removal of those screws. If you thread in one of the inserts I posted you now have metal machine threads...which should last quite a bit longerscrews i have never had any problem of my subs pulling out
No the opening is hex shaped, you thread them in using an allen wrench.How do those things work drill a hole hammer them in?
Yes, you drill a larger hole and thread in those inserts. You then never have to remove those inserts and you now have metal threads and you can just use regular bolts. I will say it may not be a bad idea to put a dab of glue on the outside of the inserts because if you tighten the bolt too tight, you'll end up backing the insert out when you go to take the bolt out, then that is a PITA. It's happened to me once or twice and I just cut the insert off the bolt with an angle grinder...So you have to drill holes them thread those in because that seems way better then just screws
