Rackstuds 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.

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).

I have seen these mentioned on youtube for probably a couple of years now but having racked hundreds of systems in however many years (probably more like a thousand) I honestly thought these were kind of a gimmick. Decided just for the heck of it to give them a shot since I'm finally assembling myself a homelab rack. All I can say is I completely understand why people love these now. The only real flaw is you wont be able to use them for everything since a lot of rails mid mount on servers and the rackstuds will interfere with rack ears on said server. If they come out with a version that gets around this I'd give them a shot but especially if you are mounting decently heavy 1U or 2U equipment solo these just make the job 100% easier. In my case I had a decently heavy 2U UPS mounted in probably about 2 minutes. While not the heaviest I've mounted solo the fact that there is no 'lean' on the UPS and it feels solid with so little effort is pretty dang nice. I also mounted a 1u switch painlessly but as it happens that switch is way too loud so it will be getting replaced. The switch does 'lean' but most of the weight is at the back of the switch and it's not like I'm worried about it somehow falling out of the rack so overall it's fine, just something to be aware of. While I doubt I'll ever use these in the DC's I work in (more's the pity) these are great for my use at home and while fairly expensive compared to the conventional rack nuts more than enough of them come in 1 pack for my needs at home. I'd definitely recommend, especially if you don't need a ton of them. Edit; I'm using the Red 2.2mm in a Vivo 22U rack I got from Amazon.

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.

Great product. Strong and able to easily hold switches and routers. I use mine on Ubiquiti gear without issue. These make it easy to get gear in and out of racks. RRP is a fair price for the product.

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.
