Does anyone know what the thread is on the Mikado 2385 main shaft clamp bolt?

I need to find a source for them.

I've slightly rounded the very end (using a good Thorpe driver) and I'm afraid to use it and end up rounding it out completely either reinstalling it now or the next time I try to remove it.

It's an 8mm long bolt. It looks like it would be the same thread as all the other 2.5mm bolts used on the 600SE but it will not thread into a 2.5mm nut so it must have a different thread spacing.

Thanks!

Have you tried 3 mm ? That's typically what they are on other brands.....

Been there, done that and old enough to know better.....

I did the same thing. It's just a standard 3mm screw. I ground the head down with a dremel so it didn't stick out.

if it ain't broke, break it.

I'm 99% sure it's not 3mm (or mine isn't). Comparing them side-by-side, there is a large visible difference.

Eddi on the V-Stabi forums just said they are standard 2.5 x 8mm

I replied:

Well, I took the 2.5 nut out of a bag of new ones. I also screwed a brand new 2.5 x 10mm bolt into it first to cut into the nylon in the locknut.

Then tried the old clamp bolt. It felt exactly like the wrong thread.

If the clamp bolt truly is the same thread, I'll try a few more 2.5 nuts today.

I'll let you know.

Thanks Cuda and Juan.

So I verified that it is indeed a 2.5mm bolt. I tried a different brand new 2.5 nut and it fit.

I just took my dremel to the 2.5x10 and cut off about 2mm

I didn't need to grind any of the head as it fit into the recess of the collar just like the original did.

Thanks again.
