What size nuts

Post by roymck » Tue Nov 22, 2016 3:15 pm

I am away from the car for a bit and want to order some nylocs, what size is the top inner wishbone nuts to replace the castellated nuts I have there, want to have them ready when I rebush.
Also the what nut size do I need for the 4 bolts that hold the trailing arms onto the rear axle.

I don't think there is a thread that has all nut and bolt sizes for the SE5,s .

Thanks Roy

Don't use nylons for the upper fulcrum/wishbone. Not enough thread to lock - that is why it is a slotted nut for a split pin. IIRC they are 11/16th unf. Readily available. I got a few from Namrick in the past - just used the last ones on the GTC last weekend.

I think it's actually 7/16 UNF?

I tend to agree about the length, it doesn't look very long to me?

7/16 slotted unf, only looking at them 1/2 an hour ago and have some on order from Namrick, well it is on my 6 anyway.

Trailing arms are 5/8 UNF and I think there is enough thread for nyloks there.

To illustrate the point, here's a nut screwed as far as it will go onto the fulcrum. note: the gap behind the nut is unthreaded, for a washer.

In the Moss TR6 catalogue they offer a nyloc for the top fulcrum, thinner nut? I wonder

Probably a "half nut"?

I think a split pin is a safe bet and i really can not see why a nyloc is an improvement ?
