7 mm grub screws
I have removed the aluminium plugs from my 2.0 litre crankshaft and put a tap through to make a 7mm thread. (I broke 3 taps doing this process!).
I now require 7 mm grub screws.
Does anyone know where I can get these? Preferably in Australia.
I could use bolts sawed off after tightend in position but prefer socket headed grub screws for ease of removal.
Thanks,
Dom

I had a terrible time finding M7 grubbs....
Took a masonary drill bit,ground the tungsten tip to 6.8mm wide,drilled the crank and then tapped it m8...
V6`s I fit m14 pipe plugs...

French cars are shit and shit expensive to service and bloody awful and unreliable and expensive and friends don't let friends drive french cars and you wait years for parts.
One thing I don't get in this crank business...
Why is it so fricken hard to drill the holes? The depth of the hardened bit should not be very large?

7mm grub screw
looks like I will be inserting 7 mm bolts tightend into position then saw off flush to the crank web.
TS_TURBO is it necessary to plug the main crank journals of 2 & 4 after drilling in the block for additional oil supply to the bearings 2 & 4

If you guys use a masonary drill bit with the tungsten tip,it will drill the nitrided crank like mild steel.Slowish speed and gentle pressure.
Like a hot knife through butter..
I dont know why you guys battle with this.

As Barry said, or, you can go to the local industrial supply house and get an appropriatly sized carbide bit. Also, don't drill your holes using the regular drill chart that uses 75% thread engagement, use a drill size that has 60% engagement and you'll not be breaking your taps.
As your steel gets harder/tougher you will need to slow your drill speed (rpm). Alignment is critical as the carbide bits, while very hard, are brittle and won't take a side load.
