R100 Series II - Server Rack Screws 100 Pack | Cage Nut Replacement | Red 2.22mm/0.086" | A Faster, Easier Solution for Rack mounting Gear in 19" Racks with Square Punched Vertical Rails

The Rackstuds R20 II have completely revolutionized the way I manage my server racks. These innovative rack screws are a huge improvement over traditional metal cage nuts, making installations and maintenance so much easier and faster. The design is ingenious—they snap into place securely and hold equipment firmly without the hassle of using tools or dealing with sharp metal edges. One of the best features of the Rackstuds is how user-friendly they are. I was able to install equipment by myself, which is often difficult with standard screws. They stay in place perfectly and allow for easy adjustments if needed. The vibrant red and yellow colors are also a plus, making it easy to spot them when working inside dimly lit racks. What really sets them apart is the durability. Despite being made of high-strength polymer, they can handle the heavy loads of my rack-mounted equipment just as well, if not better, than metal screws. I’ve never had any issues with them loosening or failing, which gives me great confidence in their performance. Overall, the Rackstuds R20 II have simplified my rack setups, made installations faster, and are much safer to use. I highly recommend these to anyone who manages server racks or IT equipment—they’re well worth the investment!

These are seriously cool. I’ve been in IT for over a decade and have used cage nuts my whole career. I’d seen these before and always thought they looked neat, but I didn’t want to spend the extra money. After trying them, I can say they’re better than cage nuts in every way. They just click in, feel surprisingly sturdy, and make assembly a lot quicker. The fit is perfect, they snap in without issues, and once the equipment is mounted it sits tight with almost no wiggle. I haven’t mounted a heavy Cisco switch yet, but I plan to at some point. Yes, they’re a little pricey at about a dollar each, but I get it. They do exactly what they should and make things easier. The only downside I’ve noticed is the clips make gear sit a bit higher. For example, my Ubiquiti UDM-Pro has thicker ears and looks slightly raised compared to the rest of the rack. Overall, I’d definitely recommend these and I’m looking forward to trying more of their products.

I absolutely love these screws, the plastic is of great quality and they are great value for the money. I personally use these to lock in my disk drives and computers into my rack mount and I couldn't be happier. They are so easy to install and use. They a couple different ones for different server racks and I had a question so I messaged the manufacturer and they were quick to get with me and to verify which one would work and they were correct. They worked good with my Riveco rack I bought also from Amazon.

One of my customers first told me about these. I was skeptical about them. I mean how strong can a plastic threaded stud be? Well, strong enough it turns out. From an engineering perspective rack mount devices, particularly items which are mount to front rails only and are 1 Rack Unit high, are a nightmare. The stress loads are rediculous. It always feels like I bought some cheap table at Ikea and as soon as I sit down it will all end in a big crash. The lower fasteners on things like switches take an awful lot of strain, and I really figured these plastic studs would just snap off and all my gear would come crashing down. So far, I have not broken one of these things though. I am careful not to over tighten them though. They are plastic threads, so there is much less chance of the screw caps backing out than with metal threads. You only need to snug them. There is no reason to put any more load on them than necessary. There are two real plusses with these. First your fingers won't be hurting and bloody after you have to rack or unrack a bunch of gear. The second plus is you can actually mount a piece of gear between two existing pieced of gear with these. With old fassion cage nuts good luck getting nuts on the back of a rail with a piece of equipement above and below where you need to mount the new stuff. You usually have to pull something out to get the room to install the nuts on the back. These all install from the front, so it's no problem at all. Do check your rail thickness though. Rack Studs come in red (for thin rails) and purple (for thick rails). Make sure you use the correct ones for your rails (Why can't the industry standardize on rail thicknesses???) Anyway, overall, I'm a fan of these things. They are a little pricy compared to standard cage nuts and screws but I'll gladly pay the difference to save my fingers, and to be able to rack gear without having to pull stuff out to install nuts before re-installing everything.

I wish I'd known about this product 2 years ago when my team was first setting up our equipment rack. We have a 9u rack with several pieces of sensitive audio and networking equipment. We have been battling a ground loop issue, and tried installing Humfrees brand isolators, which are frankly a pain in the butt to install (and leave many screws impossible to screw in. The Rackstuds are fully plastic, fully isolating the equipment from the metal frame of the rack. In addition, they are so easy to install that I would use them by default, even of electrical isolation isn't an issue. They truly install as easily as advertised, and since they install first, with a post sticking out, hanging the equipment and holding it steady while you screw on the retention knobs is so much easier than holding the equipment in place while you fumble with threading the traditional metal screws into the cage nuts one at a time. I'm never using metal cage nuts/screws ever again. I spent a total of 45 minutes installing 9u's worth of these studs, and that included the time it took to remove the metal screws and cage nuts (and throw away the Humfrees isolation tabs).

Alles ok

I recently installed the Rackstuds - R20 Rack Mount, and I couldn’t be happier with my purchase! These rack studs provide a fantastic, tool-less solution for securing my equipment. The installation was incredibly straightforward—just push them into place, and you’re good to go! The build quality is impressive; they feel sturdy and reliable, giving me confidence that my gear is secure. The flexibility of being able to easily add or remove equipment without any hassle is a game-changer for my setup. I also appreciate how they minimize the risk of cross-threading, which can be a problem with traditional rack screws. Overall, I highly recommend the Rackstuds - R20 for anyone looking to simplify their rack mounting process. They’ve made my life so much easier, and I’ll definitely be purchasing more for future expansions!

These make racking so much easier compared to cage nuts. Especially since I'm a home user without professional experience.

An excellent product. Saves a lot of time trying to install metal cage nuts, fishing for the dropped or popped ones at the bottom of the rack. Easy to install and easy to remove.

Brilliant, just superb. A work of absolute genius. 20 seconds to fit in a square rack mount hole, rock solid, no broken nails, cut finger tips or hands stabbed as you use screwdrivers to push captive nuts into square holes. Yes, they are costly, but the time saving, ease of use, and ease of securing and removing makes these a must, anything from a 1U to 4U server can be secured given the loading of these, and network hardware is a breeze. Give up on using cage nuts with racks, use these and stop wasting time, effort, and risking finger damage.
