I need a little advice please

I have stuffed the screw head on the clutch fluid cylinder.I just wanted to top up the fluid FFS

Now I have stuffed it.You would think I would have left it while it was still semi ok but no

I had to well and truly stuff it up.How can I remove it please?any advice would be appreciated.

So its a Phillips head screw right??
Do you have access to a drill?,if so can you undo the other screw??,get a
drill bit the same size as the thread on the other screw & drill it in the centre,clean all the swarf(fillings) away,remove the fluid reservoir cap & you will be able to unscrew the left over portion on the damaged screw
I hope that helps

you can try using a small centre punch and tap it anti-clockwise until finger loose or cut a groove with a hacksaw blade across the head of the screw,then give it a gentle tap with a screwdriver and then try and loosen,if its still too tight get a screwdriver and attach a set of vice grips to the shaft of screwdriver and turn screwdriver and vicegrips at the same time,then once removed replace with allen head bolts,pref stainless steel.hope this helps,good luck

Thanks you guys

It WAS a phillips but now is a crater

I did not really want to have to get stuff (crap) in the cylinder it has just been bled and that turned into a mission.A mate is calling by to check it out when he has free time before I lose patience and do more damage

Yup tapping it with a punch and drilling the head off are good options but if you haven't done those things before, because it can be a bit tricky, then be carefully careful as you can scratch and score the top up badly which will stare you in the face every time you go riding.

There's a product on the market called "Re-Coil Re-Grip" it's a fluid filled with diamond fragments, designed to aid the gripping of stripped fasteners, comes in a small Twink sized bottle for around $15. Worst comes to worst, buy a Screw Extractor for around $10 for a small one.

go down the road of a screw extractor if you have no other way of getting it out, it's not easy to use a punch or hacksaw etc with a flush (csk head) screw, you will need a drill bit smaller in diameter than the screw to get the extractor started....

I think that the screws on the top of the mastercyl are countersunk so just progressively drilling the head off will allow you to remove the cover and grip the protruding shank with some sort of grips.
Stud extractors are just fabulous right up until the fraction of a second that they snap..! Then you are stuck with a stud that now has a piece of undrillable material jambed in it. By memory they are a 4 mm screw which will need a very fine drill and extractor, too risky. It's a steel screw in an aluminium housing that (if it was recently bled so it must have been off recently) is not frozen, just tight and my guess is you may have not had quite the right screwdriver for the job (there are phillips screwdrivers and there are also phillips screwdrivers). So it shouldn't be too hard to remove.
