Bolts! Nuts! Fasteners!

[Squid]

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

See, thats why you dont buy a European bike.

[gatch]

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

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.

18mm ring spanners don't come in your standard ring and open ender sets.

............

[Ixion]

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

[Ocean1]

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

It's a wring spanner.



This is a Ring spanner:

Do you sell M10 x 1.0 ?

[AllanB]

the mating surfaces are greater and the angle is easier to go up.

Hell yeah baby thats some dam fine screw talk.



I like the way engines come with spare bolts and nuts when you rebuild them.

[The Lone Rider]

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?

[scumdog]

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.

[xwhatsit]

There's a rooted XS250 at Squiggles... I'm going to steal all the nuts and bolts

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)
