Number plate allen key rounded off?!?

[munchkincoupe]

I bought some of these from ebay to replace the rounded off Audi screws eBay - The UK's Online Marketplacegone to replace a bulb today and one of the bolt heads has rounded off

How do I get a rounded allen key bolt out please????

Thanks

I got it out by, grabbing the head with some pliers (the ones that lock in place) and then just twisting them out! Was a total pain though, good luck!

Well I would not use the one you bought either, I would acquire stainless steel ones.

I would try WD 40 to loosen the bolt, and try again.
It is quite hard to remove a bold with a rounded head, especially if you cannot get grips onto the head. I would drill it out with a small drill being careful to make sure it is in the centre and not to drill into the hole thread. By rights you need a screw extractor that is like a tap with a reverse thread on it that tightens into the old bolt and winds it out.

I must stress it is quite a skilled job with small bolts.

Good luck with it

try a torx head that's slightly to big and a hammer then untighten. tends to work when I balls screw heads up

hi did you get the bolt out with the locking plies if yes fine,if no try grinding a slot in the head of the screw with a bradall (very small grinder )this will let you use a screw driver,

Try a small anti-clockwise drill bit (stud removal kit type) into the head generally this will bring it out if not, then, the hole you made (small) put a stud extractor in out itll come. not sure where you are but if near Brizzol i have the kit to do it with if you can't get it out

Thanks for the advice fellas

Would these be a better idea then M3 A4 Stainless Steel Button Head Socket Screws MARINE GRADE Small Quantities | eBay

if so I will order them in 12mm and have another go at removal on wednesday. Will probably go with the slot and screwdriver method as I'm quite handy with my dremel disc cutters
