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?

    While I can’t speak for your rack in particular, most pre threaded racks are either 10-32 or 10-24 screws.

    You can buy them easily on Amazon.

    I work in television, and in our equipment room we have 50 racks that are pre threaded. And we use these: [Amazon link](Penn Elcom S1032/HP/WA/100 High Point Rack Screws with Washers - Set of 100 https://a.co/d/g13kPzw)

      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.

            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!
