Just wondering if there is anyone out there who has experience with Accuride, model 123 hinges. These have some Pozidriv screws which, in my haste, I’ve stripped the heads on. These are adjusting screws (up/down, in/out, left/right). Apparently the screws aren’t meant to be fully removed for replacement when the customer has stripped the heads. 
Any secrets I should be aware of?  Or, do I just need to suck it up and buy new hinges along with the proper Pozidriv screwdriver?
