Identify this exhaust nut

AltaNorton · Sep 13, 2011

I saw this on eBay. It's the exact same as the ones from my engine. Original according to my dad who said he never changed them. I can't seem to find them for sale anywhere or even any other bikes that have them. Anyone know what bikes they were typically used on and where I might be able to get them? Mine are all bent and I would like to find more like these rather than the other 750 ones with the three big fins.

They don't look like alloy, but if they are, don't buy them, alloy exhaust nuts are pure caca.

Now ya tell me, I'd planned to use slick light same thermal expansion Al ones on Ms Peel. Figure I'll have to spring load em to stay snug, it not then bronze ones.

Looks suspiciously like my original steel ones except cleaned up. You can get the real nice bronze ones from Walridge for about $30.

I have a bunch of them used from that era , some good, most buggered up by emergency roadside repairs, but OMG they are of better visual quality than those castings of caca that I smell here. Been wrong before.

You will be able to put them on, but you may never be able to take them off or snug them if they back out a bit. You are right, get the bronze ones.

The Al ones I snagged on evilbay, are finely machined product not crude cast ground like the one in subject line. BTW the proper term I've been chided on by real experts, is hollow bolt not a nut, as threads on outside not inside, just like the fork cap 'nuts' are really bolts too.

I'll use Milk of Magnesia as hi temp anti-seize and drill some holes to use spring to hold them snug as long as that can. Here's a view of em. The extra factor in Ms Peel is she's got the worlds only one piece 2-one headers so traps the ring bolts on.
