APC server rack with threaded holes instead of cage nuts

snekerpimp@lemmy.world to Selfhosted@lemmy.world – 12 points –

Just picked up an APC 48u server rack. There were no pictures of it in the post and I did not notice until I got it home and set up, that the rack rails have threaded holes instead of square cage nut holes. I can’t seem to determine the thread size and pitch, and have a thread gauge coming. Until then, does anyone know anything about this? The people I grabbed it from had used self tapping machine screws and drove them in with an impact wrench. Is this what APC had intended, or is there some $300 proprietary screw I have to buy from them?

This is what I thought too, but both #10 threaded bolts I have are too small, one will thread, the 24 ones I believe, but you can wiggle them, enough to wiggle them out with out turning them.

They're 12-24, we use these at work.

#12-24 are way to big, can’t even get them to catch the first thread.

I know you said this is wrong, but my APC racks that look just like that also use 12-24 pilot point screws. They do have a little cutting notch that clears out the paint when you screw them in though

This is honestly the answer I was looking for. Someone who has this in service. Thank you so much. I’ve seen these bolts on APCs website, I was thinking it was for cutting the powder coat but wanted to make sure. Thank you again!
