Cylinder base studs in stainless

Have you tried the club spares? I don't know if they have fasteners but worth a try. Also, I have read that stainless doesn't go too well with dissimilar metals, I thing aluminium may be one of them.

I have tinned nuts with my heavy soldering iron for cosmetic reasons and they look zinced. You could do the same with the stud end.

Are there issues with them staying tight? Wasn't it standard british motorcycle design practice was for exposed nuts and bolts to be encouraged to rust up solid, in the dim, dark days before Loctite.

Barrel to head studs - same question.

An alternative might be to BZP the old ones to mimic cadmium.

I had a problem with stainless cylinder head fixings, so much so I lost one of the under head sleeve nuts and only one of the others was still tight after only 50 miles. This caused a head gasket to fail which didn't impress me a lot. I replaced them all with genuine fixings from Norton. When checking the thread form, albeit too late, they weren't that good so with a bit of vibration they didn't stand a chance. My barrel base nuts are still stainlessso I've had to keep an eye on those but have applied a bit of Loctite. Furthermore I've also lost two nuts and had others loosenoff on engine plate/crankcasestuds so I've replaced copperslip with Loctite. I wont be using stainless so much again.

I have been using stainless nuts and fasteners for years with no problems of them slackening off. I use copaslip on assembly too. I don't use stainless for head bolts though and I haven't used it for cylinder base studs either.

I stick with stainless (sometimes nylock for critical applications) because where I live the roads are covered in salt for a lot of the year. Modern BZP fasteners are a rusty mess after one season.

Hello the Best bet is to contact Nooks Nuts . On Ebay shops He will sort you out with your needs and no stainless steel , My Manxman had Stainless steel nuts but they kept coming lose , so I found this guy On Ebay . And emailed him he help me with the right size and nice nickel plated nuts and bolts and the washers was free , for my business late I bought £36 pounds worth of mixed nuts and bolts and again free washers all sizes and they fit nice too in Cycles tread he did say and thing you need we will make it for you. just send us the old ones for the sizes , hope this may help you to , happy hunting , yours anna j

Be careful when buying studs from a hardware supplier. I believe that engine case studs have two different threads on them. Coarse threads for the crankcase side and fine threads for the nut side.

I'm sure that if I am wrong someone will correct me.

nooks nuts knows what he is doing when it come to nuts and blots and studs and washers .he makes stuff for BSA And Triumph as well

I use as much stainless as I can, most of mine came from Molnar Manx (yes the engine guy) the fasteners are perfect, prices are good, and he will make you anything you want as a custom order if its not on the website. Some I got from Norvil.

On fasteners that arent getting loc-tight, I use coppa-slip to prevent galling on stainless fasteners.

stainless steel galling info for the techies:

Just in case you go looking for 'nooky' (am I allowed to say that?) his ebay store name is 'nooky's nuts';

http://stores.ebay.co.uk/Nookys-Nuts?_trksid=p2047675.l2563

He also trades as www.nookysnuts.com

I have used him and his fixings seem good quality/value. He is especially useful for BSC/CEI as he does 'mixed packs' that are very useful to have.

He also has a stand at Kempton Park Bike jumble.

P.S. I have no assocaition with him - just a happy customer

Hello yes I see What you get for the man I had dump all my stainless nuts ,they were a half a size out, and lose on the threads so you welcome to Molnar manx , just like the exhaust pipes that was in stainless steel it was the worst fitting exhaust pipes I ever seen . they were all over the place, So I stick to Nooks Nuts There far superior !!! And Cheaper

too

well you live and lean But some do not learn at all,

HT Engineering make excellent stainless nuts, bolts, set screws etc. They are motorcyclists and understand the need for high quality products.

With respect Anna, Molnar Manx fasteners are perfect size, you must have had some Chinese stuff??? Its not the materials at fault it was poor workmanship that you have found. I had a stainless exhaust on my Commando years ago, made by Epco just a few hours away from me in the USA, best fitting exhaust system I have had on any Norton I have owned. There are many poorly made fasteners on the market, in all materials. Not saying Nookie has bad nuts, just saying there are other companys that also make good stuff, stainless or otherwise.

I have also had very good success with "British Tool & Fasteners" here in the USA. In addition to tools & fasteners, they have a ton of info about all the bBritish thread forms & bolt head markings.

hello yes that maybe and I have no idea were they were made but they were on the bike when I bought it . I did ring him about them but he said there not made by me , but I had the invoices with his name on them, but this did not stop him selling them to someone did it, junk or no junk, the exhaust pipes are that bad I would not sell them to my worst enemy what a wast of stainless steel . there bee going in the scrap bin. and the nut that would not tighten up , and in stainless steel too , but not any more I dumped the lot, and fitted some nice nuts and bolts from Nook's Nut's his washer are the nicest fitting washers I ever seen in 49 years he maker's some lovely nuts and bolts .you should all give him a try. you will not be disappointed So I do recommend Nook's Nut;s I am just one very satisfied customer , I do love Nook's Nut;s its something to go Nut's about Yours Anna J

Had a look at Nooky's Nuts website. Everything seems to be BZP, or have I missed something? If so, it's not the place to look for stainless nuts, bolts etc. which iswhat this thread is about.

Will Horgan at Stainless Classics makes and stocks ahuge range of standard nuts & bolts, and lots of special fasteners, for Commando and other Nortons. He can make anything to order, and uses the right grade of stainless for the particular task. The finishis superb. He copied every single fastener for me on a restoration of a 1938 OHC Norton.
