Hi,

I was wondering if anyone could tell the the type of driver I need to tighten the M8/20 screw on the door. It's not the main hinge but the wee black bracket in between. I thought it was a torx 40 but it isnt and only managed to strip the head of the screw.

I have a new screw now from my dealer (ordered via phone and posted) but the spares department could not tell me what head was on it. The part number is N 908 961 01.

If anyone could help or point me in the right direction where I can get a tool to tighten this correctly I would be most happy.

Thanks,

John

Does it look like a star, if so try a spline set.

Should this not be merged with this thread?

:duck: Sorry, couldn't resist.

Yes, it looks like a star. Never heard of a spline set.

Thanks.

They come in various guises but here is an example

Avenue35, Britool tools, Draper tools, Facom tools, Kamasa tools, Laser tools, Sealey tools, Silva, Silverline tools and Sykes-Pickavant Products. Haynes Books and Manuals - Laser Spline Bit Set - 3/8D 6pc"]Laser spline set

That should do you, Either GSF or Halfords sell it too.

Thanks guys,

Thats what I'm after.

I always assumed these were torx, if not so whats the difference between spline and torx?

Torx are 6 point

I think the spline set is 12 point

Isn't the German type a triple square (which is slightly different from spline drive)?

So you may probably be able to get a torx bit into a spline screw but not vice versa (might explain why I was able to get at some of the trim screws on mine )

Glad to see I am not the only one who has to tighten this screw a couple of times a year. Only on the drivers side door though (strange ?!?!?)

Isn't the drivers door the one opened the most?

Tried using studlock/threadlock or similar?

Yeah, but it will butcher it fairly quickly.

Torx seem to have a slight angle on them so even if they fit in the slot perfectly, they won't be 100% engaged.
