Title: Best way to remove stripped screw?
Post by: the_Journeyman on August 06, 2011, 08:08:02 AM
Picked up a new air screw for my 1999 M750.  The one on the horizontal carb has the head stripped.  What is the best way to get that out?  I have an extractor-type bit that is made to work left-handed.  Should I chuck that up in my drill and use that?  It's brass, so the bit should bite in easily.

Have a link to the bit you're talking about?

Before you try the drill, you can also use a hacksaw or Dremel to notch the head and use a flathead screw driver to remove it.

Good luck! I just dealt with one on the exhaust clamp.

This screw has really limited access.

Those tricks won't work.  ;)

Yea, it's down in a hole, so I couldn't get to it to notch it.  I did get it out!

Here's what I used.  I just put put the smallest one on a bit driver, tapped lightly with a hammer as I turned.  Basically I made a light duty impact driver.

For the future you could grab a few sizes of left handed (counter clockwise fluted) drill bits. I've had a couple stripped screws out with just those drill bits when prepping them to use the normal square or spiral extractors

The danger in that in this particular circumstance is the consequence of drilling through to the seat of the screw.

I think he used the right tool.

I was afraid to put a drill on it because of the concern DP mentioned, and with it being brass, I didn't want to chew it up any worse.

Oh that was just a hand waving general comment from a tool geek.
