Hi all,
I'm looking for metric M1.6 and M1.4 bolts in lengths above 20mm, with
a cheese or lens head, and hopefully philips bitting. Located in the
EU. Does anyone know where to get them? I've been unlucky finding a
source thus far. I can get 20mm slotted, but those are too short. I
can't find above 20mm anywhere.

Thanks

Try this one: biggest store in Stockholm.

I'm having trouble browsing the swedish version of the page, and the
english just outright disables orders... would you mind checking if
they have these screws?

I dunno what a "lens" head is, nor whether you are looking in the UK or elsewhere, but have you tried:



They just might have something near.

Colin.

I?ll do that later this evening.

These people may be able to supply something:



Geoff.

Sorry, they dont have them that size.
G?ran

The reason you can't find them is that no one makes them.

If they don't make 'em, no one does.

"They" don't make M1.6 at 20 mm length and this size is available from
Conrad as well as multiple other stores. Please don't spread FUD.

I need a length above 20mm.

Thanks Colin, they don't have them.
Thanks Geoffrey, if I have to have them made then I'll probably make
them myself at the local rent-a-cnc.
Thanks G?ran.

Uh, they make M1.6 up to 20mm. Please learn to click buttons on a website.

Why do you even ask these outlandish off-topic requests here?

You linked to the black one which only goes up to 16mm. It doesn't
matter. It proves nothing. The fact that some fly by night corner shop
in China doesn't have a specific screw doesn't mean someone else won't
have them. I posted here because people are helpful here, so take a
hint from others and stop being negative.

Speaking of taking a hint, so far, you've found NO ONE that makes your ridiculous screw size.

Have you considered they might not be made because they're not manufacturable? Have you looked at the aspect ratio?

They don't even make partially threaded screws in that size.

It's a good bet that your precious screws will be made in China by a "corner shop" anyhow.

Even specialty shops stop at 10mm length.

It's not being negative, this is an engineering forum, we look at facts. At least, we're supposed to.

You might ask this in the model engineering group in groups.io or the
miniature machine tools group also on groups.io.

Some of these folks make operational miniature milling machines and those
must have a lead screw longer than 20mm (but likely also larger diameter
than 1.4 or 1.6mm). When you see what some of these folks do, cutting an
M1.4 x 20+mm screw does not seem unreasonable. They might also tell you to
try M1.4 and M1.6 dies and thread what you need though I suspect the torque
on the stock might be a problem.

Buddy, I don't know what your problem is. Obviously you get very upset
by questions about screws. Take a hike. WTF.

I have a small-scale CNC lathe here, but I was hoping to avoid using
it for a screw of this size.

The chances of finding anyone having that sort of screw in their portofolio are (very) slim to none, and even if they do you'll probably have to by several hundreds of them...
Solutions that may work for you are allthread with a soldered-on nut and cut a slot in it, or make your own.
Joe Pieczynski has done a video on how to single-point (!) such small threads on a lathe.:

Curious - how does he pull the stock out of the chuck while the lathe
is running? He does that around the two and a half minute mark.

he doesn't, it only appear so because the video is edited to shorten it.
Bruce

Makes sense! It really looked like he was doing it... probably just a
joke of sorts.
