V8 Rocker cover ht lead clip thread size
Discussion
On the rover v8 (chim griff etc) there are holes in the top to hold ht lead retaining clips.
Anyone know what thread size they are
Fyi they are bigger than 4mm and smaller than 5mm.
I suspect they are imperial 3/16 unf but just guessing.
Why do I ask. I want to tidy up my ht leads using some chromed clips I have so what to buy some suitable set screws to hold them in place.

I've just seen my TVR for the 1st time since the summer 2017 (wow pretty!), unscrewed that bolt, it does look like the one pictured above.
Measures 3/16" (4.76mm) dia with what looks to be a 1/16" pitch thread, didn't manage to identify what that equates to though. Does look like a self tapper.

Thanks fellas unfortunately self tapers wont work with the clips I have as they are two piece and defo need nuts and bolts to hold them together.
So, still really need to find what threads are.
The two piece HT lead clips are intended to be used as additions to the fixed clips. They should be placed along the HT leads to maintain separation So, still really need to find what threads are.
As said they are self tappers so no thread in the hole until you put a self tapping screw in.
If you want to put something different in there then you will need to drill and tap. However if you do you will need to drill right through as it is almost impossible to tap a shallow blind hole.

I think there's a reason for the rocker covers not having the holes threaded. Currently, a self-tapper clamps the plastic HT lead retainers down (on mine) but they can still twist and move slightly, allowing for flexing in the HT cables.
If the holes were threaded, you'd either have to tighten right down so that the lead retainers were clamped stationary or leave the bolt / screw loose in which case the vibration would undo it. This would be OK on the o/s rocker cover where the clamp sits in the fins in the cover, but not on the n/s.

I’ve been looking for the answer to this question for my MGB V8. Hence finding this forum.
By trial and error I have now found the right size for the MGB V8. The thread for these is 3/8 UNC or 10 - 24, it therefore would make sense that this would be the case in other applications?
Hopefully this will assist someone.
