left hand drill bits and brake rotor screw size

[92EcoDiesel Jetta]

just bought a set of these NEIKO 13PC TITANIUM LEFT HAND DRILL BIT SET #10038a


URL: http://pages.ebay.com/link/?nav=item.view&id=281309382684&alt=web  to drill out the broken flat head screw in the  brake rotor. does anyone know the length and thread size? I'd like to have it on hand before I start the job.

Not for sure but I think it is an m6-1.0x10mm flat socket head. If it is not a 6 then it is a 5-.8 x10mm or so

[Rock3tman]

Checked my parts from Parts Place: Theman53 is correct, it's a 6mm x 1.0 thread flathead (it's a phillips head instead of hex). The length of mine seems to be 8mm from the start of the threads to the end of the threads.

I played hell getting the Phillips headed ones out of my rotors when I did the front bearings.  Replaced with hex heads and went stainless with some anti-seize on them.

Thanks for the thread size. ORCoaster, did you use an impact screwdriver, the type that you hit with a hammer? In my experience that is the tool with the most chance of success.

I called the VW dealer and got this part number N106 483 01 $0.75 ea. they did not have stock but says the Audi dealer down the road has 16. What is the torque specs on that screw? I imagine it shouldn't be very tight since it's just 1 teenie weenie screw for index
ing purposes. Too tight might actually stress it after you torque down the wheel lug nut bolts.

You could save yourself some trouble next time and just not put the screw in...

Or just drill the head off so you have a stud to index the rotor with.

The screws has been broken off since I bought it 4 years ago. The rotor woukd shift when mounting the wheel and lug bolt won't thread in and I have to take the wheel off to line the holes up and try again. Very frustrating.t

[air-cooled or diesel]

i find those screws break regularly, (or seize) its a little pain to line up holes w/rotor holes, an allen head or hex head would be good, not too tight, just snug. the only time it seems to be to be a big problem if late at night and you forgot a light, changing a tire could be difficult. the technique i like is to line up hole at about top and you can line up rim easier, once you get 1 started your ok. (use anti-seize)

92EcoDiesel Jetta,  I used brute wrist strength as I don't own one of those impact hammer type jobbies.  I just soaked in penetrating fluid,did the heat and cool with torch and air cool.  I did make sure I used my best bit of the bunch on the screws.  I have my set of screwdrivers that are reserved from daily use for times like this where no slippage is acceptable. 

My son has since given me one of those battery operated impact drivers and I find it useful in situations like this but now I need a set of points that can take the impact jarring without breaking the bits, to bits.  Anyone have a recommendation on those?

Went to the Audi dealer asked for p/n N106 483 01 and got these $1.25 ea. Stainless torx

Cheap Rotor Bling,  You will no longer kick yourself when you go to do work in the future.  Good choice.

Impact screwdriver rarely fails me.  Anytime that screw goes back in its treated with anti seize.

In the auto parts store, go to the "help" section.  They have a pack of rotor screws for a Honda that's a perfect fit.

I favor the 1.25 stainless hex.  Sporty and extremely practical.  Everyone has a set of hex wrenches or tips that go on a ratchet for that extra leverage when needed.  And as noted, anti-seize every time it comes off.

The ones from Audi are Torx, as the pics clearly shows. You like hex better? Torx is better than hex, less likely to strip imo.
