Any Ideas How To Remove The Tiny Injector Screws?

How can I get these out if the screws are all stripped. Why don't mechanics use anti-seize. It's as if they want their parts to break.

Good idea by the way - the guy who replaced those screws with cap screws, and his spec is correct. 8mm Socket.

(Please don't tell me I would have to individually drill them out. If so, I'm just leaving them alone)

There is a hammer tool which you can insert a large screw driver end into. You hit the tool with a hammer and it rotates each time you hit it, acting like an impact drill. Also, with hitting it with a hammer, you are creating significant downforce onto the screw which helps prevent further slipping. My experience, one or two taps then you can unscrew them by hand. I forget the name of the tool. Anyone know?

The replacement screws from the dealer are hex head screw/bolts to make life a little easier!

OK I'll try some of these suggestions - but the injector assembly is pretty fragile, if I start banging anything, I could crack the plastic though.

A good pair of vice grips on clamped down on the head of the screw may prove fruitful..

10" vice grips as said or take a hacksaw and cut a standard slot in each head. #3 Philips should have been used to avoid stripping.

Can't hurt anything unless you hit the injector with the hammer! The rail is well supported and the injector are in the rail. I had to use an impact screwdriver as well! Remove the fuel rail off the engine it'll be easier!

I used vice grips to get mine off. I didnt realize the dealer now uses hex screws/bolts instead of their original soft screws. It cost $0.55 per 4 screws/bolts at lowes.

yep, it's decently sturdy. if paranoid, one can put a socket under the bowl to as to keep the pintle cap suspended, and all the force will just be on the bowl/socket. plastic won't break like that.

if the rail is already out of the car tho, just go straight for the vicegrips.

You are the master. It worked PERFECTLY and got them all out. Size 10 vice grips.

[Oh and edit - everybody else who suggested]

Thanks,
