Hello,

 

I'm trying to find motherboard/pcb standoffs with a thread diameter of at most 3mm and at least a total length of 25mm. Ideally they would be brass or steel, but at this point I'd be okay with anything.

 

The trouble I'm having is that I also need the threads to be at least 10mm long.

 

The sticking point seems to be that the standard for thread lengths of standoffs for this diameter of threads all seem to be 4mm, 6mm, or 8mm long, but again I need a thread that is at least 10mm long. I've searched through Digikey, Keystone electronics, and some other outlets for standoffs with the right properties, but I haven't had any luck.

 

I already had a few lying around that are perfect, so I know they exist, but I haven't had any luck finding any similar ones online. The ones I already possess appear to be 25mm long in total with 10mm long threads which are about ~2.5mm wide.

 

Does anyone know where I could find ones like these?

Are these standoffs going into a blind threaded hole. If not, can you get a 15mm brass standoff with female threads on both ends and backscrew the standoff? You can also get the 15mm standoffs with female threads, I believe those are 3mm threads, and cut off the threaded portion of a 3mm machine screw to length, screw the stud into the standoff then apply a tiny amount of thin CA glue at the standoff/stud location.

Do they have to be brass, or metal?  Nylon standoffs come in a larger selection of sizes than the metal ones.  Plastic wil work too and add a ground strap where needed.
