Afternoon folks. I require a little assistance if possible. I'm trying to source some fastenings for something I'm working on and I even don't know what they're called. I don't even know if they exist but I'm sure there must be a use for such a device. I need to put a metal sleeve through a flat (board/plate/slab type) object. I need the centre of the sleeve to be threaded. I'm imagining something like the set-up that's shown in my crappy MSPaint drawing below. Can anyone help me by telling me what to call them or point me to where I can buy them? Thanks in advance.

Struggling. The nearest I can find are Bushing Nuts like so (from eBay)...
Not what you need, but may give you ideas for keywords.

A rivnut would probably work as well.

Aren't they called Sleeve Bolts or barrel bolts?
You often get them in a flat pack for joining 2 cabinets together..

OK, I tried sleeve and bush in combination with all sorts of terms, but there are some other ideas of terms to try them with. Thanks guys - more work needed in my search, I think.

What's thrown me is the requirement for the centre of the sleeve to be threaded. You mean the through-hole, not just that the two halves screw together?

Yes, the two halves will need to connect together but I want to be able to screw something down through the centre of the whole thing.

Get on eBay and track down a seller called airborne101 - the shop should be called KaTech bushings. These look like bushings that sometimes get used in rear shocks on bikes and he MIGHT be able to help. No promises though.

What would stop the bushing rotating as you tighten up the securing bolt (or setscrew) ?
PS What size thread are you wanting in the centre ?

I was planning to fix it in hole with epoxy. I looked at plates and flanges that could be screwed or bolted down but they needed more room on the surface than I was prepared to give them. If this idea doesn't come to fruition, then I'll have to go down that route.
Chris: Thanks I'll take a look.

That's not really an influential factor at the moment.

Oh.
OK thanks for your suggestions so far anyway.

Chris - what about a different approach? Could you use a long nut to give the thread that you need and gently tap/epoxy it into a slightly undersized hole?

I'm not sure that will work Martin, as it needs to be adjustable, so the internal thread will be subject to the occasional up/down tweak. It'll be supporting a quarter share of about 25-30kg.

I do think these exist - if the bay doesn't work find a specialist bike repair shop and ask them. I've used fittings like this for mounting shocks on bikes. I'm not home till the 9th ish but I will keep an eye on this thread and if you haven't found anything by then I will have a rake about for you. Could also be worth a look on chain reaction cycles or look under shock mounting hardware.

Is that meant to be a link to a Rawl Nut?
