Nut and Bolt set
« on: 14.10. 2019 07:30 »
I’m starting to put back together my 1953 A10 plunger after rebuilding the engine and having various parts powder coated or sprayed.
Exciting times!

I am based in Durham.

Does anybody know where I can find a good quality stainless nut and bolt set for a plunger?
Or a list of sizes/threads I can take to a supplier?
The old nuts and bolts fit superbly but look out of place next to a freshly sprayed bike.

Many thanks
Richard

I mostly used Draganfly during my restoration.

There is a comprehensive nut and bolt reference  in the Literature  Section of this very forum. It is the first entry at the moment. With part numbers from your own reference or Draganfly's online catalogue, identification of nuts, bolts, studs and washers is easy. The chart tells you what size and thread the various part numbers are.

 A cheap set of Cycle Thread taps and dies to clean up powder coated threads will save hours of frustration. Cheap carbon steel will do. Even new threads can benefit from a quick clean up, as in some cases the manufacturing tolerances between old original parts and modern ones are not quite right for easy assembly. I would recommend threadlock on all fastenings, as this will also aid dismantling in the future as well as holding things together, whether you go for stainless or mild steel.

 Request... Admin can you please post links once again to these handy references. Thanks.

stainless will cost well over a grand good quality plating is cheap for your existing parts if there in good condition and Nookys Nuts are well priced for mild steel

I have had joy with stainless parts and fasteners from Barleycorn Engineering

Not cheap, but high quality.
D Middleton and son in Batley were very helpful to me with stainless nuts and bolts.

I prefer to have the originals (fasteners and specials) replated if possible. Known tested metallurgy and guaranteed to fit. What's not to like.. ;)

Well there is a little problem with getting existing fasteners replated.
The originals were generally Cadmium plated because it does not cause hydrogen embrittlement.
Nickel or zinc plate will cause hydrogen to be dissolved into the steel rendering it brittle and the higher the alloy ( ie stronger ) the bolt the worse the effect will be.
Add to that the fasteners are quite old and I would not bother myself and fit new fasteners.
