Bolts! Nuts! Fasteners!

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?

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.

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)

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:

Do you sell M10 x 1.0 ?

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

Dude you have NO idea how much it hurt when I moved house and had to dump tonnes of those usefull bits n bobs.
