View Full Version : Bolts! Nuts! Fasteners!

I never have enough of them. Bolts, nuts, screws, washers... With the amount of junk I have accumulated since I got into bikes a little while ago, I have a little collection of spares, but it's not really adequate.
An old dodger told me I could go to a wrecker and ask if I could buy a box of assorted leftovers. Wreckers ain't what they used to be -- do they perform this `service'?

Go for new ones, most old ones have done there job already, as some are only designed to do a specific job and only once.
I have rebuilt a few bikes and dealing with new fasteners is much better, always have stock of typical sizes & grades and only use nyloks once.
Availability is better than it used to be nowadays.
Nuts and bolts and other fasteners are very specific on Japanese vehicles - you won't be able to buy that stuff over the counter.I save everything - every engine or gearbox at work gets stripped and all bolts and studs are saved.Most rare are 6,8 and 10mm nuts in Japanese sizes and threads - they seldom use nuts,everything is caged.The nuts are flanged,have washers built in or are self locking - these are gold to me.
Find an old car engine - strip and save.

see if anyone you know is wreckin a car for a demolition derby, I have done a few and the amount of randon strange peculiar and wondeful items I come across and save is mind boggling. see if anyone you know is wrecking a car and get all the bits and pieces you can find!!!
Or carry a tool set with you and every time you see a bike parked up, flog a few nuts and stuff off it. just a few mind, not all of them, just the ones you dont think the owner will notice....

Sounds like a plan, EVERONE knows that Hondas come with waaaaaaay to many bolts anyways. :bash:
It'll make em lighter too so therefore = faster :eek5:
The trouble is the Japs don't use metric nuts and bolts they use the OTHER metric nuts and bolts.
So ordinary metric bolts and nuts that are easy and cheap to get are no good, you have to have the OTHER ones which aren't.
WTF is the point of a non standard standard. At least the Briddish got that sorted. BSF FTW.
Yes,it's the Japs that are doing it wrong - but because everyone only works on Japanese bikes and cars...they think any other system is wrong.
BSF FTW.
B.S is about right, there is so many different kinds of b.s threads, at least metric is easier to work out without a pitch gauge.
As for random fasteners I can usually turn up my own, for example today I turned up a m10x1 grub screw, 5mm long in stainless and put a flat head screwdriver slot in the top, its the little dust cap off my front brake caliper.
Looks good too.

Standard spec' for Dynabolt-type nuts.
Not cripplingly expensive, even if you have to buy the whole bolt.
Can get 'em in SS too.

But can you get them in all the weird pitches that the Japanese like to use? I suspect they are just in ISO pitch.That's why I save all the Japanese nuts....they fit all the Japanese bolts.

No.
As a matter of interest, how many of the finer threads found on jappers are in fact ISO fine and how many are pure mongrel?
They may very well be ISO fine - but every nut and bolt supplier who say they have everything,don't.6 and 8mm are ok,but 10 and 12mm are a different story,I've never found a supplier who can supply them.Not just the thread pitch,but also the various lengths,shanks etc.Strip a complete Japanese car,save every bolt you can find - then dump them on the counter and ask for the same please.I bet they can't do a fraction of them.

I'm a fastener noob. When is metric not metric?

They simply use Metric Fine.
M4/.75 mm pitch
M5/.75
M6/1
M8/1.25
M10/1.25
The bigger threads on axles etc are 1.5mm pitch.
All easy to find especially at the likes of Atom Fasteners in East Tamaki who have a great range.

so euro cars and bikes are std metric as aopposed to "jap" metric?

See, thats why you dont buy a European bike. ;)

Metric is metric, people just get confused with the different pitchs that are available for different thread diameters. If you are handy with a ruler you can always tell what they are.
When you get into imperial threads thats when your head will explode, as there is so many that are similar, just used for different applications, theres like 7 or 8 kinds of british standard threads alone lol.

Most of the western world (England,Europe,Australia,and even the USA if they dare to admit it) use the ISO system - they said,''we are using this,and now we are all the same''.Japan does not totally use ISO.This is mainly to do with head sizes,but also thread pitch as well.Have a look at your BMW tool kit,it will have 11,13,15,17 and 19mm spanners,a Japanese tool kit will have 10,12,14,17,19mm.

Im sorry dude you're wrong. There are basicly TWO metric threads Metric fine and metric coarse.
For example
M10x1.5 is metric course and M10 x 1.25 is metric fine.
The diffence is that the 1.25 has a shallower angle and doesnt dig as deep into the bolt.
Incidently a silly point -The stronger thread is actually the 1.25 because the mating surfaces are greater and the angle is easier to go up.
Kinda like a wedge really
Holey shit all that time selling nuts n bolts and i remember summat

Except of course, for the 14 mm bolts/nuts with 13 mm heads. And the 15mm sprinkled around.
I've been coming across 18mm heads lately (BMW cars).I've got 18mm sockets....but I could only get a ring spanner on them.18mm ring spanners don't come in your standard ring and open ender sets.I'm sure someone will invent 0.5mm steps soon.

That's not a ring spanner it's an open ender

Do you sell M10 x 1.0 ?

Hell yeah baby thats some dam fine screw talk.
I like the way engines come with spare bolts and nuts when you rebuild them.

One thing that might help, although not in the immediate, is make a habit of striping anything household or outdoor that you are throwing out of it's screws and washers and nuts.
I guess going to Mitre 10 is out of the question? :)

Meh, I often drill out the hole, tap it with UNC and use a 'proper' bolt.
Or use 'proper' nuts and bolts where I can.
Then I just need my SAE sockets'n'wrenches.

There's a rooted XS250 at Squiggles... I'm going to steal all the nuts and bolts :2thumbsup
M10x1.5 is metric course and M10 x 1.25 is metric fine.
The diffence is that the 1.25 has a shallower angle and doesnt dig as deep into the bolt.
The angle (60 degrees) is the same on both,the difference is depth which in turn effects threads per mm.
You can cut metric with the same tip tool (if it is a universal and not set)

Bearing in mind, as has been said already, there's ISO Fine - and in some diameters there's ISO Extra Fine. Basically there's not much true mongrel out there, just some of it is the lesser common Extra Fine and weird stuff like M11, still recognised as a standard on some thread charts.
I was told once that older Guzzi's had a lot of M7 & M11 on them. It's not just the Jappa's.

Yea mate but the ramp angle is different --ie the number of turns per cm down the bolt. Ramp angle dictates the force required or the force able to be applied.
The way I was explained it is that metric coarse is like a short wedge running round the bolt whereas metric fine is a longer wedge
Provided of course we have bolts of same tensile strenth and quality of thread finish.

Anyway to answer the origonal poster.Ages ago I put a post up telling people about a trailer place in Manukau city--Triton trailer components.
They have a selection box of M8/m6 and M5 metric coarse bolts for $10.00 looked like a good start point for someone.
I think Cycletreads also has a nut n bolt selection.

Is that all youve got , pfffttttt .... part timer junkie.
I started in the Fastening game (Winwood Screws and Fasteners) so many years ago i cant remember.
When i started screws were sold per the GROSS ( 144) and when they strted to pack emm in 200s stocktake was only an afternoon , not 2 days lol.
In the true sence of the word there is no such thing as Metric and Metric Fine, They are all actually ISO but Metric is refered to as a diametre and pitch referance size which specifies the thread you want.
For reasons of ease the industry started to call one Metric iso and one Metric fine, but thats dosnt actually cover it all so a third was deemed Metric Extra Fine lol .
EG; M 10 x 1.5 (ISO) , M10 x 1.25 ( Fine ) , M10 x 1.0 (Extra Fine)
When Winwood got taken over by Boustead , i took a course and to this day i am still the only certified individual (not a company) that was registered with the N.Z Fastening Guild as a specialist in technical and application Nobody else can ever get that because the Guild is no
longer around lmfao: msn-wink:

M10 x 1.0 is pretty common on pushbikes I think: isnt that the size that crank ring bolts are?
