I have a stripped tiny hex screw preventing me from popping the lid of one of my components.
I've tried a screw extractor from Canadian Tire which didn't work. Does anyone know where or how to fix this?

Drill it out would be your best bet I would think or take it to a machine shop, post a pic if you can.

Extractor should work. Try hammering it in lightly to get it to bite. Better yet find a different hex bit. Tolerances on hex bits are all over the place. Some are noticeably larger than others in the same nominal size.

I have been successful with a star bit, tilting it hoping to catch an edge

if you can't wedge a square driver (Robertson) or allen key or something in the hole of the screw to remove it next step is use a small diamond point chisel to tap into the outside head of the screw head, at about a 30 deg angle and using a small hammer tap the screw loose

I have in the past used a drop of high shear strength 2 part epoxy on the end of a disposable but close fitting allen key. Be careful not to overflow the head of the screw, once set you should be able to apply enough force to remove the screw

use a Robertson bit that bottoms in the bore, it will work.

Also apply liquid wrench and wait for 15 minutes.

lol...thanks for all the feedback
problem is that it is a tiny and countersunk screw
I'm going to try a few of the suggestions and hopefully leave the component and my fingers undamaged

If nothing else works.... really small cutting disc on a Dremel, hold it sideways to cut a flat groove in the screw head,
Then use a flat screw driver.
Be careful with cutting, start small and a small cut is enough.
Try it first on a spare screw.

A simple trick to loosen screws and set the drive bit. select the correct bit size, insert it into the fastener, then smartly whack! the driver. This will shock the threads of the fastener, set the bit deeper into the fastener head, and make the less likely to strip. All this is wasted on where you are right now....try and find a drive bit that most closely matches the screw head. Try the whacking trick.

WARNING... If you are not sure that the screw you are attempting to remove holds circuit boards or other sensitive components do not bang the screws. Otherwise this trick has worked well for me for many years.

Good luck
