Where can I get one of these?

[bosco659]

I need a piece of hardware like this. I sheared one off on my bIke stand. It’s threaded 8mm x 1.25 on the shank but 5/16” would be ok. The cross drilled hole doesn’t need to be threaded and the body need not be hexagonal - round is ok. Any ideas where I might get a piece like this? Thx.

Well if I needed one I would find a chunk of barstock either round or hex that was the right size and chuck it in the lathe and turn it down to the diameter for that thread and run a die over it. I soupose someone with more skills than me would be just cutting the threads while it was chucked in the lathe.

If you don't have a lathe you need to make friends with someone who does!

Unfortunately I don’t have a lathe. I guess I’ll have to search locally for someone to make this for me.

A threaded ball joint rod end is sort of similar:

You could also drill a cross hole in a coupling nut:

and add a piece of threaded rod.
If you dig around enough on the McMaster-Carr site you might find a better solution.

Thx was also thinking a female rod end joint might be adapted for this use. I can get one in M8 x M8.

Here’s where it goes. It’s the one on the left that failed. As mentioned, my fault. I hung the bike on the stand without properly torquing (to 145 ftlbs) the 16mm dia main bolt. Rotational force sheared the fastener.

Dont know what dimension is critical but there exists that type

Extra nut and welding and drilling the hole ??? ?? Or something

Get a bolt and a nut, run the nut up to the head, weld it there, cross drill, done.
I'm a master at additive part manufacturing with a mig....................
you can build up the nut/head for added strength grind to shape drill the cross hole.
Also check for machine bushings at the hardware to make a larger section for the cross drilled hole.

 

[bosco659]

Thx. Didn’t think about stacking a nut and welding it. If I put a chamfer on the edges to be welded I should get good penetration even with my limited welding skills. Would be nice to spin it on a lathe to clean it up after welding. Another reason why I should have a small lathe!

Just space the nut a bit back from the bolt head give you plenty of room to fill the gap with weld.
Chuck it in the drill press make round it with an angle grinder. ;^)

Do an image search on Google for Eye bolts, Swivel Bolts and Swing bolts. You may see something suitable I hope...

Thx. Often times searching for something is difficult if you don’t use the correct terminology. I’m going to see if I can buy something on line in case my home made, @gggGary piece doesn't work out as planned.

 

[bosco659]

Made this. Not the same as the original but will be stronger. The threaded section that snapped had a very small diameter and it’s being replaced by my home made fitting with an M8 - 1.25, 10.9 shcs (Not the bolt in the pic). Not the prettiest piece but should work.

I guess it's a little late, but I found this in a box of stuff today.

Now you got a spare
