Nut and Bolt supplier UK.

Im after a supplier of M9x1mm threaded bolts – I can't seem to find a supplier in the UK.

Plenty on ebay but all come from China and want silly money for postage. There must be a decent nut and bolt supplier out there.

That's a Bugatti size thread! The owners club sell them but they are not cheap.

if you can make your own try Tracy tools, on here for taps or dies. I have always found them very helpful. Noel.

How long?
A quick internet search suggests they may be used on some Vauxhall flywheels

And also DeLorean, but check the pitch is correct

Thanks – Im in need of 30 for a special project – ive already seen the tap and die set at Tracy tools and have the tap on order I just didn't want to make the bolts –

There available through a chinese ebay account but as mentioned not paying those prices –

there must be a UK supplier of odd size pitches –

[Mike HurleyParticipant @mikehurley60381]

No Guarantee but try West Bromwich Fasteners in the midlands – huge range and sell small quants via their trade counter. Have had loads of oddments from them in the past. Worth an enquiry if you're stuck.

All the best

Please try to have a sense of commercial reality.

M9 in any pitch is a non-preferred size. M9 x 1.25 pitch is standard metric coarse. M9 x 1.0 pitch is fine thread.

How many, in this specification, of any length, would someone sell in a year?

You are expecting a supplier to keep a box of the specific length you require on the shelf just so you can have 30 pieces out of that box.

[Me.Participant @me1]

I appreciate that and do realise that the fine 9mm thread is very odd, but a quick internet search did find them, but not in the UK.

the actual application size is M9x1 x 7mm long so even a 30mm bolt would do so easily cut down.

For those interested im making a traction control sensor for a friends National Hill Climb car – on the front hubs there are retaining rings which hold the front wheel bearings in place – the rings have equally space 8mm holes around the outer edge – the bolts are needed for the Hall effect pick up – as the hole is already at 8mm next best approiach is to tap them 9mm and as the ring is only 7mm thick a nice fine 1mm pitch thread seems the best way.

They will be fitted and then the head machined down so it forms a square rather than hex as the pick up is much happier with the flat edge of the square than the potentially sharp edge of a hex…. a lot of work and the added work of having to make 30 bolts and thread each one is adding more work……

Just to satisfy my idle curiosity:

What would be the price of this over-expensive shipment from China ?

With the greatest respect it does sound like a difficult way of cracking the nut.

[Swarf MakerParticipant @swarfmaker85383]

How about using the much derided imperial (fraction) system and an outdated thread standard?

3/8" X 26tpi BSc is readily available in the motorcycle restoration world.

A decent product and price from 'Nooky's Nuts' may satisfy your need.

I think I would think a bit outside the box. Like a slightly smaller standard thread (3/8”?), buy in longer bolts of the correct strength, rethread and turn the shank to the fitted size. Or pick a more sensible size for the project.

[noel shelleyParticipant @noelshelley55608]

With a HUGE range of threads available why use an odd metric ? The Hall effect device wont be fussy if it's imperial. or even steel pins and loctite. Noel.

[Me.Participant @me1]

The spacer ring is approx 100mm in dia with 26 equally spaced 8mm holes already drill approx 12mm from the very outer edge increasing the size of the hole to the next best thread pitch isn't an option the ring is made of a titanium alloy as well – formula 1 stuff apparently…..

I will be tapping every other hole to take the bolt and then macheing the leading edge of each bolt to line up with the pick up.

As the hole is already drilled to 8mm the 9×1 thread would be my easiest option. 9 x 1.25 would reduce the amount of threads per hole as the ring is only 6mm thick.

Looks like i will be buying the die from Tracy tools……..

[JellyParticipant @jelly]

Try emailing Accu?

They will make small orders of custom fasteners on a couple of day call-off and the prices are reasonable for that level of service because convenient low volume just in time manufacturing is literally their entire business model.

I'd either helicoil for 8mm or make a custom target.

By custom target I mean a turned steel item wth a shank that fits the drilled holes and a head that suits the hall effect sensor geometery. Use loctite stud and bearing retainer to keep them in the holes.
Alternatively can you arange the sensor to detect the holes instead of the metal?

If you used a variable reluctance sensor you can add a pole piece to "turn" the sensing through 90 degrees if you can't fit the sensor end on.

Edit. Just noted the ring is titanium so hole sensing not an option. You don't really want to be tapping it if you don't  have to so either a custon target or a threaded insert bonded in would be my choice.

If you are shying away from drilling the material, do you think any tap you buy from Tracy Tools will do the job in your aerospace billet material?

As above, JB Weld a steel insert in. It will fit with the 'advanced technology' theme you have mentioned. Threaded fasteners are just so yesterday. Glue is used on the wings on aeroplanes these days.

[DiogenesIIParticipant @diogenesii]

Do you really mean these rings were designed to be retained by twenty-six M8 fasteners?

..even cursory consideration indicates that the loads on this assembly were foreseen to be absolutely massive..

As I understand the fasteners are not for assembly there are targets for a sensor

Buy longer 9mm bolts, saw the end off and re-thread 9 x 1.0. 30 bolts like that would not take too long – less time than the length of this discussion.

[bernard towersParticipant @bernardtowers37738]

Just one M8 HT bolt in shear is something like a ton why would you need all them?

[not done it yetParticipant @notdoneityet]

The last reluctor ring I bought was for a peugeot 607 and cost about three quid. Press fit. Peugeot don’t sell them – they were going to supply a new driveshaft for about £450 (and likely didn’t include VAT🙁 ).

[Me.Participant @me1]

FYI – the ring is threaded with a 47 mm x 1 mm thread – Inner hub is left handed thread the outer is right handed = to hold it into the bearing housing – the outer edge holes are there for weight saving and also a special tool is used in the holes to tighten the ring into the housing – hence the need for he holes – if i use every other hole there is still a hole to use the special tool in to tighten the ring.

I could post a pic but were getting away from my original post- I just need a good supplier of odd sized hardware in the UK – the concept has been planned and all variables considered – its just the bolts with the desired pitch which is proving the sticking point.
