The V8 Owners Forum -

Does anyone know where I can get these in the UK? I am taking apart my Holley and the metering block is kept on by some of the screws. I can prob grind a flat head down but thought I would ask the questions first.
Cheers

Have never heard of clutch head screws?
My weber 500 is held together with torx / star drive type screws.
Have you got a pic of a clutch head screw please.

Yeah me too, found a pic in Google images. My 390 Holley didn't have 'em though.
If no luck, maybe one of the parts or tuning shops could give give eyou an idea Sean, they must've come across them.

Ahh those things.
They sell them in a screw and fixings shop that I use. I would try a commrcial supplier of fixings and security screws etc..
I use apex fasteners in Slough. They do a lot of variations on this type of security screw.

I always thought those things were just for holding toilet cubicals and things together and not carbs I wonder why they used them on something that someday will definitely have to come apart? Anyway hardware places like Grahams will have then and probably screwfix but I don't think it matters what you get as these things aren't meant to come out with anything even if it is the proper driver.

The ones in the link called clutch heads are not the same as used in the Holley - the Holley ones are like an allen/Torx cup but shaped like a figure 8 and are meant to be removed.

Yeah thanks mate I saw those items but I only need the one screw driver so I guess a grinding job it may be.
