Flange bolts - where to buy?

[psyguy]

i'm wondering if anyone knows where to buy stainless steel flange bolts (M6 in particular), in auckland or anywhere else if they want to ship
also need M10 flange nuts, fine thread, stainless

i tried the following places in auckland with no luck whatsoever
anzor fasteners (they claim the nz's largest stainless selection)
atom fasteners
edl fasteners
the bolt shop

cheers

Wurth do a range of OEM fasteners, far from cheap. Talk to Motu?

Edit;
M10 Flange Nuts = Easy
Stainless = Umm, Maybe....
Metric Fine (M10x1.25) = Oooh, possibly...
Metric Fine (M10x1.0) = Yeah, right!

Combination of the 3 = If you find them in Enzed you should buy two Lotto tickets the same day!

If none of those guys don't have them you might be outta luck in NZ -maybe Auckland Engineering Supplies (AES)?

You might give Blackwoods Paykels a try. Look at :

www.blackwoodspaykels.co.nz

for your nearest stockist. One thing is that you have to know exactly what you want with them 'cos they may not know. Sometimes you have to wait if its not stocked but they have always come through with what I need.

There is an engineering supply shop at the roundabout on Cavendish and Lambie Drive in Manukau City. They know their stuff. Cant remember the name. I'll have to get back to you.

tried wurth today
the website looked promissing but the answer was disapointing - no flange bolts or fine threaded flange nuts

paykels phone number goes straight to the fax machine...

will try later

Flange bolts? Sounds familiar, but what do you need them for (what application)?

Why stainless,why not the real deal? Flanges are usually retained by studs and nuts,and this is the best way to go.The material used for exhaust studs is high quality,made for the job.Before putting any cyl head or other component into the scrap we removed all studs and filed then in the ''stud bin''.Any broken or stripped studs were replaced from there.I had dozens and dozens of them,but sold my shop a couple of weeks ago,tough bickies.Go to a cyl head repair shop (some guy on here works at one?),they will have heaps too.

If it's for an exhaust fitting, you don't want stainless. Heat expansion rate is wrong. What Mr Motu said.

Aren't flange bolts bolts with a flange built into the head (like an in-built washer)? Used for things like bolting brake discs to wheels. I'm still looking for flange head socket head machine screws - OEM was outta stock for what I wanted.

It depends - what if the exhaust is stainless?

The real question is "is it ferritic or austenitic" - part of my work has been to behold the power of austenitic steel (e.g. some stainless steels) in chewing up expensive plant when it gets hot...

He hasn't said what he want them for....I presumed when he said flange he meant exhaust flange,which is the only common flange on a motorcycle (I presume it is a motorcycle he's working on) If he's talking a bolt or nut like your picture with a built in washer (often they are serrated and act as a spring washer),then again they are OE,made for a particular application on the vehicle.Perhaps a full explanation of what is wanted and intended use would help,but not often supplied in help requests.

Wouldn't brake disk retaining bolts be high tensile ?

What is the obsession with stainless fasteners? Sure, they look pretty so reserve their use for bits you want to look pretty but don't have any real function.

Stainless fasteners are inevitably 316 grade. Threads gall and aluminium housings into which they're threaded, corrode. Stainless fasteners also fatigue and break - just great for brake master cylinder mounts... NOT!

For an exhaust bolt the absolute last material you want is stainless! 316 can't handle the heat cycling - you need a duplex stainless for that. And when the time comes to remove it it's sure to neck and snap.
