I was trying to change the air filters on my scooter and stripped some of the phillips head (actually JIS) screws. Whats the best way to get them out?
Got these at Lowes. If the screw isn't too far gone, they work well. Make sure to get Grabit #1, #2, and #3.
Otherwise, you may have to use a Dremel.

If the head it where you can get to them and clamp vise grips on, that works sometimes. You might want to replace them with Allen screws.
I tried the vice grips but couldn't get a good grip in the screw head. One of them is set way back and hard to get at. I will need to replace some of these screws. The ones I don't replace will get some anti seize compound on them when I put them back in. I can't believe how tightly these were torqued. Or maybe they just got stuck because they have been on so long.
I think a trip to Lowes is coming up.
Another trick that works sometimes is to use a cutoff disc on a Dremel to cut a slot for a flat blade screwdriver. Again, it depends on access.
A lot of the 70's bikes had real soft Phillips screws everywhere. Impact screw drivers where mandatory. You also needed bits that fit the screws perfectly.
I went to Lowes and got the Grabit extractor. The guy helping me there showed me the right size for the screw. I was going to buy a whole kit but let him talk me into just one extractor. That was a mistake because it just made a bigger hole in the screw head. I need to go back and get a bigger one. My next problem is that this extractor will not fit into any of my extension drill bit holders. It needs a deeper socket so I will have to go see if they have something like that.

I found some old craftsman extractor bits I bought a long time ago. They don't work either. I can't get them to bite on the screw head. They just dig a bigger hole.

I did get one out using vise grips but there is no way to get vise grips on the remaining two.
You could jb weld a bolt or something that you can grab onto the head of your stripped screw and then see if you can get a hold of it. Sounds like your gonna have to replace it anyway.
I have use side cutter pliers to remove screws. Put one point in the center stripped part and one side on the outside of the screw head. Sqeeze and turn the pliers.
Post a photo of the bad screw and the situation you are facing. Somebody here will surely have your solution.
I will most likely drill the heads off the screws and remove the cover. Then I should be able to get vise grips on what's left and remove them.
This is what I'm dealing with:

The stripped screws are top center and another behind the round access hole bottom center.
Yeah, that's a tough one. Looks like your right about drilling the heads off, ect. Maybe somebody will have another idea.

My opinion: You just provided your own solution.
Got the screws out. Changed the filters which were filthy. Put anti seize on the screws before putting them back in. It was a PITA but should be much easier next time.
Glad you got it. Did you drill the heads off? Glad you shared - might help somebody.
I got one screw out with vise grips. The other 2 were innaccesable with vice grips so I drilled the head off of one. I was using the Craftsman Extractor bit's to drill them and the third one ended up coming out before the head was drilled off. I use anti seize compound on all the screws before putting them back. I replaced the damaged ones with some screws from Lowe's but I should get some better screws with Allen heads or something I can use a socket on. Any suggestions on where to get some bolts? The size is #10-32x3/4 IN.
This was the filter that was so hard to get at:

Scooter has 7,000 miles and the filter is supposed to be replaced at 12K. Glad I didn't wait until then.
Ace Hardware always has the best bolt/screw selection.
#10-/4 IN may fit but, I'd be surprised if the screws aren't metric unless the holes have been drilled and retapped previously.
Anyway, since this thread may be helpful for other stuck, stripped, or broken screw victims, I have one other method that works sometimes. Obtain some left hand twist drill bits and drill the screws with a drill running in reverse. Sometimes the screw will back out while you're drilling. I've been able to make that work a few times. If it doesn't work you still have the option to use an extractor.

Good point. The screws are probably supposed to be M5. A 10/32 is close and will work for a bit but could eventually strip because the thread pitch is not identical. If it is indeed supposed to be M5, I would pick up some M5 socket head (allen type) screws.

Thanks for the info. I took the screw to Lowes and they just tried it in various holes until it fit. They wroked just fine on the bike but I wasn't planning to make them permanent replacements.
Fastenal is a good local source for different styles of screws.
I agree that they are probably metric.
I know it's a little late now, but you could've used an extractor that looks like a socket. http://www.amazon.com/Tools-Bolt-Grip-Extractor-5-Piece-394001/dp/B0000CCXVZ
I think I have a set, not sure if they would be small enough.
Found this on the internet:
"The 10-32 (10 gauge, 32 threads per inch) is very close to the M5x0.8 mm/thread. The 1/32-inch thread is 0.03125 inch per thread. Multiply by 2.54 cm/inch and you would get 0.794 mm per thread, which may be tolerably close to 0.8 mm of the metric screw. As already noted, the 10-gauge screws major diameter of 0.1891is going to be slightly smaller than 0.19685 of the 5 mm screw (by approximately 8 thousandths). Since a "tight fit" is in the range of 2 thousandths, you will have trouble torquing the wrong sized screw into a 5mm threaded hole or nut."
So, according to that, the 10/32 screw will fit in an M5 hole better than an M5 screw in a 10/32 hole.
While this has been a PIA for Win, it's been educational for some of us.

I bet Win learned a few new words in the process, maybe even made up a few.

It was educational for me as well. I'm sure I'll have to deal with stripped screw heads again someday.
Thanks everyone for the advice and info.

There's a Fastenal near me so I'll go check it out.
I found these on Amazon. I used this vendor for the M5 I needed for my BMW.

I recommend getting a set of these in case you ever come across this problem again. They fit over the head of the bolt and work with just about any screw that has approx 1mm of edge to grab hold of. The only extractors i've ever found that absolutely work as advertised.
I stopped at Fastenal and got some M5-0.8 x 20 Button head socket cap screws. They are the correct size for what I need. They use a rather small 3mm Allen wrench. I'd prefer something with a more sturdy head but these are better than what was on there and will work for now.
bblass, those extractors look like they should work. I try to pick up a set in the not too distant future.
At Lowe's they sell the Irwin brand of the extractors for $19.95. http://www.lowes.com/pd_577634-281-394001_0__?productId=50146292&Ntt=

It looks like this kit is designed for larger bolts.
