Fastener help
 

What is the correct name for this fastener and where can I get some? It's a nut with an allen head, but it's metric. This one has a 10mm thread; the one I need would be 8x1.25

Barrel nut.......McMaster-Carr?

Barrel nut used on the exhaust system, started, etc. Ditch them and get copper nuts.

Ah, but that's not what I'm going to use it for. On the Type 3 motor with the single carb, the lower carb nut is impossible to get to. My idea is to use one of these instead.

I made one tonight as an experiment

Do you have a Fastenal out there?

I have also been pleasantly surprised with the local Ace Hardware for random fasteners...

I get most of my hardware (nuts, bolts, etc.) for the 911, two old Volvos and a Series I Land Rover from Ace. They have everything I need and I don't have to walk for miles and miles as in a big box store. Go ye also and be pleasantly surprised!

M8 x 1.25 barrel nuts are used on the 3.2 Carrera intake and there are three on each side of the cam towers.

Let LubeMaster help in the matter of 'screw'...;)
