Where to get odd sized bolts?

[Gazdaman]

Sort of bike related, although I actually need these bolts for a table.

I need some M6 counter sunk machine screws. (that's no problem).
But I need a 1.25 pitch thread, which seems impossible to get hold of!

eBay has come up blank and Google doesn't seem to be finding me much better. I know they exist because I've got one that came with the table.
And it must be metric, because the thread pitch is measured correctly in metric. So it must be M6 aswell.

If it makes you feel any better I can't find any either, checked all the usual places I use for funny sized bolts and found nada.

Best bet is to phone a local nut and bolt place and ask, I usually use these guys for odd sized fixings when the internet fails me and they are always really helpful.

The only other thing I can think of is maybe I've measured it wrong. It looks like an Ikea type table, so it can't be that weird-a-size.

The width of the bolt is 6mm from tip of thread to tip of thread. And it must be 1.25 pitch, because I used a thread pitch gauge.

I think I'll do a bit of digging on where it came from, and see if they can provide any new ones.

Don't think I've ever seen them either, at that pitch do they go into a metal female thread or are they a bit of a pointed self tapper type thing??
You can get M6x1.25 taps and dies if they are a proper formed thread, only suggestion is get an ordinary M6x1 countersunk bolt with a long enough plain shank and thread that with an M6x1,25 die
Tracy tools, the god of all things threaded, do the taps and dies

I sold metric fastenings for a number of years and I can honestly say I have never come across, or heard of a M6x1.25 bolt or screw. Standard and fine pitches for M6 are 1mm and 0.75mm so where this 1.25 pitch comes from I have no idea.
I would be interested to know how you are measuring the diameter of the screw in question, ruler or vernier? If you are using a ruler, it may well be you are looking at a 1/4" screw with an Imperial thread, just a thought.

[DrDonnyBrago]

I can't see Ikea using some unusual pitch screw and I also cant see them using anything other than metric fasteners, certainly worth measuring the pitch with an imperial pitch gauge if you know someone with one though.


Try a standard m6 bolt in it, it just falls down the middle then it is not M6 - how you could measure it that badly I don't know. If it seems to fit but binds after about half a turn then you may well have a strange M6 1mm pitch bolt.

Brabbin and Rudd.

Ikea tend to use special sizes in my experience of them. So you can't get them anywhere else.

[Gazdaman]

I measured it with a ruler, I'm still shite at reading my standard vernier.

It screws into a female thread that's sunk into the wood of the table. Turns out it was from Tesco, not Ikea.

I will try with an imperial pitch gauge, I think that's most likely, that it's an imperial size or something.
But yes, I have considered threading a plain shanked countersunk bolt. And if it really comes to it, that's what I'll do.

I'm back on this again!

So M6 is very close to being 1/4". 2.54cm, half is 12.7mm, quarter is 6.35mm. I've been measuring with a steel rule, so that could well be right.

1.25 pitch metric thread would be what in imperial?

I don't even know what the 1.25 signifies, other than some writing on my pitch gauge. I take it it's one thread every 1.25mm?

Gaz

[Gazdaman]

Some crappy maths might suggest I want 20 threads per inch. That'll be 1.27mm between threads (if that is how metric pitch is measured).

1/4" Whitworth 20tpi is still to this day the standard size for a camera tripod mount. You might be able to try one of them in the hole.

Nice one! Just bought a test piece, if it fits the thread I'll splash out and buy the 24 (!) bolts I need.

Nice one guys, thanks.

1.25 is a pretty standard pitch for bike threads on a honda at least!!

[Raffles]

[bikenut]

from memory 1/4 whit is quite a course thread unlike 6mm x 1.25 which is relatively fine.

1.25 pitch is used on hondas as well as yam, prob suzi and kwak as well. :D
