Rackstuds - P20 Rack Mount II - Rack Screws for Server Rack Rails 19" Square Punched Vertical Rails, Perfect Cage Nut Replacement, Rack Nuts, Rack Studs Rack Mount Screws - Purple 3.2mm/0.126" 20-Pack

These have been a brilliant piece of kit to have for installing items on my home server rack, easy to put in, strong enough for everything I have and quick to add and 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.

It has always been a nightmare with the nuts and screws for server racks, do you have the correct ones for metric or imperial measures? Can you get the old cage nuts off without breaking your knuckles?These marvelous little things do away with all that fuss and can even be done one handed, which is great if you are solo installing a piece of kit worth several thousand of your local currency!They are also surprisingly strong, able to take the weight of a couple servers quite comfortably... though I still recommend caution if you are going to do that.The colour of the pieces is also quite helpful if you drop the pieces as they stand out... as long as you don't have a mass of similar colour cables to search through!

These things are lovely, installation is a breeze, they seem really secure, basically they do everything they advertise BUT even buying a 100 pack they are 46p each! Any rack I build for work is going to need at least a hundred so normal rack screws it is.... However my rack at home is all rack studs as I like to shuffle stuff around and I like the tooless nature. Also my bag was missing 1 yellow part!

Usually I would use nuts/bolts, tried these on a whim as they cost more than nuts/bolts, however glad I did, they are much easier to use and represent considerable time saving, especially if a single engineer is installing kit.

Here's my review. If you ever used traditional cage nuts with bolts you will never use them again after using Rack Studs!

These are so easy to fit and make placing my router and switches a breeze. It allows one handed fitting which makes the job so easy and less chance of damage. Great product.

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.
