Rackstuds R100 Series II Rack Mount Screws - Server Rack Screws and Cage Nuts Replacement for Server Rack Rails 19" Square Punched Vertical Rail Without Using Cage Nut tool - Red 2.22mm/0.086 100 Pack

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.

I first saw these rackstuds on a LTT youtube video and thought I'd buy a pack to try and I wasn't disappointed. They are very easy to use and saves on first aid plasters. I would prefer to see them in a plain black colour though. I would like to switch to these on our network installs but unless they can be purchased in large bulk packs they may not be cost effective.

I've not built many racks in my time, but this is the first time I've used rack studs and it certainly won't be the last pack I buy. They're amazing & make life so much easier, especially if you might move things around your rack.

A little pricy for what they are, but they are well made, support suprisingly well, do the advertised job and are easy enough to install for hot fixing. Better than the standard metal fixings? Meh, only if you're prepared to pay a premium to not chase after a screwdriver.

Mounting equipment with rack studs is really quick - there's no risk of scratching equipment and no need for extra tools. They're surprisingly strong for a piece of plastic, something which surprised me when I racked networking equipment, but when fitted they feel just as secure as normal cage nuts.Only downside is the nut itself protrudes about an inch. If the door of your rack is near flush with the cage, you may have issues closing it. For me, it hasn't been a problem but definitely something to be aware of.

Like many people, these cage nuts peaked my interest when I saw them, so I decided to buy them for my 4U rack.I'm going to keep them, but I'm not sure if these are exactly what I need for this particular rack.On a positive note, they're easy to install and once they're on, sliding 1U components into your rack becomes easy because the red screws are so long.It's easy to screw the black caps on too, but it's no quicker tightening the caps up than using a Phillips screwdriver with regular M6 screws. Of course, with the rack studs, you don't have to worry about finding a screwdriver.The benefit to using this method is that once the rack studs are on, you won't have to deal with washers and screws falling to the ground and sliding things in an out becomes simple. So I can see why so many people opt for them if they're changing things around a lot.So why am I torn?Well, from a cosmetic point of view, I don't think they look as good. Whereas regular M6 screws only pop out a few millimetres from your rack, the rack studs will make your rack appear 25mm/2.5cm deeper (around 1 inch ). If the red screws were shorter, it would be perfect.I don't think this will be a big problem for large rack setups, but with my rack only being 15cm deep to start with, it kind of looks out of place. The yellow washers look a little out of place against black racks too.I'm still in the process of setting my rack up and will possibly be adding a power strip and router, but when things are setup, I don't see me changing things around that often.Due to this, I'll probably revert back to M6 Cage nuts and screws as they're more discrete due to their smaller footprint.As I said, I'll probably keep them as I may be setting up a second rack setup somewhere else in the house later and could use them for that.If you don't mind the caps sticking out, these are undoubtedly a practical alternative to regular M6 Cage nuts and screws.

This is a game changer, making the sometimes fiddly and often awkward task of fitting cage nuts to a rack. Unfortunately for me I was trying to use them with a studio rack from the USA, so the actual rack holes were about 2 mm too small ( who knew they came in different sizes🙁) but having seen them, if they could fit I’d be ordering more tomorrow. AND as they are plastic, they prevent cosmetic scratches and marks to the front plate of your equipment, which for me is very important!

Took me a second to get the hang of fitting them but once you do its super fast and makes life much easier, especially in a home lab when you may be moving things around a lot.

If you have a rack mount sever do yourself a favor and give these a try, they make install / maintenance easier and are worth the money!

Other reviewers are missing the point. Do you even rackmount bro?The manufacturer is likewise missing the point in their advertisement. They do an absolutely horrible job of extolling the true virtues of their overpriced product. (price will be the last point in my review.)Cage nuts are trivial to install and remove. You can use an expensive tool $35 or a cheap tool $1. Or a screwdriver. For about $10 you can get a toyota camry level of tool that just gets the job done and isn't otherwise much to look at. For $35 and up you can get a ferrari level of tool that is overpriced, doesn't do it's core job any better than a camry, but gives the owner some extra satisfaction. Regardless of tool choice, cage nut installation and removal is a solved problem.The actual problems these things solve is:1. cage nut quality is all over the board. People buy the dirt cheap unbranded chinacom cage nuts and then complain that they suck. duh. buy APC or other brand name for consistent performance. Even then, the cost is still in the noise so why worry about pennies. just like your basic screw and nut which seems like you can't mess it up, well it turns out that these things are in fact precision parts, requiring careful quality control.whereas, rackstuds are of consistent high quality from a single manufacturer. you can't buy a poorly performing one -- yet.2. if you are especially fat-fingered, or not dexterous, you may drop the cage nuts as they go in or out. there are times where this creates a problem. the design of the rackstud doesn't preclude dropping them (esp. the yellow "washer" part), but since they are completely handled from the front with no tool, the risk is very, very much reduced.3. cage nuts have inherent slop. most importantly, vertically. sometimes you may find that something doesn't fit in the opening left for it, due to tolerances eaten up by the cage nut slop and varying hole clearances of the device mounting tabs. you'll sometimes have to loosen up the surrounding equipment. not super awful, but nonetheless annoying. it's not possible to mount something "dead center" in the rack space allotted for it. normally everything sits at the lower extreme afforded by the cage nut and you can end up with a device not fitting properly. further, this puts a certain pressure on the cage nut, although personally i've never experienced a failure due to this. this might be more of an issue for racks that have to be transported.whereas, rackstuds have no detectable slop, only the inherent tolerance of the part itself. the rackstud itself is always right in the center of the slot opening. the only vertical slop is due to the hole clearance of the device's mounting tabs.4. cage nuts, depending on manufacturer, often make it impossible to secure something tight/flat/perpendicular to the rails. the nut itself often cannot pull up against the cage securely as if the nut/cage/rail assembly were a single piece, so you end up with devices and shelves that have an inherent wobbliness to them. this can be very annoying for some situations.whereas rackstuds install perfectly tight against the rail as a solid assembly, and give you a flat reference surface against which your equipment mates.5. best for last! especially so for heavier equipment, cage nuts don't provide any guide for installing a device. if you have a gap underneath you have to very awkwardly balance the device while starting 2 bolts to stabilize it in place. because of the long depth of most devices, even just a few pounds can be difficult. and the smaller the opening below, the more difficult because you can't reach underneath very well. this can be super challenging. i've never heard of anyone else doing this, but i use 2 long shoulder screws as guides, similar to how guide pins can be used to install wheels on bolt-mounted uprights, like BMW. (american cars tend to use studs, not bolts.) even though the solution is simple, it's annoying and it's an extra unnecessary installation/removal step.whereas rackstuds are, well , studs. so you have a built-in guide for install/remove.==========now for the downsides.1. the price is absolutely horrible. definitely not worth it. i think they are missing the mark on the price/volume curve. obviously these are essentially free to manufacture (plastic basically costs nothing). of course they put a lot of design work into it and want to maximize return early on, but at this price they are killing their sales volume, IMHO. made in NZ which drives up the cost but still, it's plastic.2. i wish they would make a nut version, for mounting equipment with captive screws. all the benefits 1-4 above would still be captured vs cage nuts. likely it would have to have a rivnut insert. i'm guessing plastic threads have to be formed differently than metal ones.as a side note, COUNT your studs. amazon shipped me a package missing many studs and all the thumbscrew/nuts. clearly this was a customer return that some useless degenerate waste of space sent back after using a bunch. if the price were more reasonable this wouldn't happen ... or if amazon would throw away returns rather than put them back in inventory as new. these ship in a zipper pouch that you can't tell if it's ever been opened. rackstuds should use a sealed kind of pouch instead where you have to tear the seal on first use. if the thumbscrews hadn't been missing i wouldn't have noticed that i was shorted on the studs as well.<breathe>

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.
