I am in need of “shoulder” screws, please see attached pictures. Not quite a carriage bolt, these screws are typically used to clamp something to a tube, in this case, Bowden Touriste calipers to a seat stay or fork blades.

The threads pictured are 5mm in diameter and 7mm in length. I am look for at least 3 screws and nuts 5mm in diameter and a minimum of 15mm in length. While I prefer vintage, I’ll take any potential source. Thank you.

Delighted to read it is not anything medical.

These folks are sure to have what you require.

Extremely knowledgeable and helpful.

They may even be able to offer them in a choice of finishes.

Very familiar with the requests of bicycle people...

That was my thought too, particularly given that I had my shoulder screwed together after a complete separation. I kept the screw after they took it out, too.
