AC InfinityCarbon Steel 12/24 Rack Screws and Nylon Washers. 50-piece set for equipment server racks, enclosures, and cabinets.

I stripped the heads of 3 out of 12 screws installed. I was using a #1 Phillips screw driver, and it just doesn't fit tight enough. And once the screw driver jumps, you are better off to unscrew it, and use a new screw, because it is easy to round out thee head. The black coating comes off almost immediately.The head needs to be deeper, so the Phillips bit fits deeper into the head. The black coating is useless, and it is best to leave it off. A hard grade steal would also help. The black storage jar is also too awkward to use, and the screws come in a ziplock bag anyways, and I found it easier to use them out of the bag.

It's okay not the strongest screw but If you are carfull it's okay

These screws seemed like a decent value but ended up being very frustrating to use. If I was using these on a job site I would ban the company from any future projects as almost every screw would not tighten.The problem is that the major diameter pushes on the edge of the ANSI minimum spec which is .2078" while these measure in at .2090". This is already an issue because the rack manufacturer is going to abide by the ANSI standard as well so they may run up to .2150", however it much more of a problem because rack screws are a softer material to prevent damage to the rack. The combination of pushing the lower edge of the spec and soft material makes these screws useless because they lose threading (they strip) as soon as any amount of tightening force is applied.Do not buy them, you will be very frustrated when you can't rack your equipment.

It’s just a pack of black screws (and washers), right? Yes, but besides looking great, they don’t come in a bag or container that once opened is prone to spilling or losing.Instead, it comes in a really handsome, black container — with a foam-lined floor that reduces the impact of movement — that is very convenient to leave in the rack.I know it’s absurd to praise a product for its packaging but in this case, for such a commodity product, it goes above-and-beyond in a way that is truly practical. Highly recommend.

I bought these screws when I added new shelves to my Middle Atlantic audio rack. I thought rack screws were standard and that one size fits all. Not true. These are 10-24 thread count. I needed 10-32 thread count so they were too big. My fault. So, be careful to know what size you need and make sure to get that size. That said, they are nicely packaged and appear to be of high quality.
