40C Series II - Server Rack Screws for 19" Rails, Perfect Cage Nut Replacement - 80 Studs; 40 of Each Size/Color

Wasn't sure which ones to get for my server cabinet so I went with one of these. I now know which ones to get packs of and will be looking forward to getting more

I have been in the IT field for over 20 years and I hate cage nuts I started using this product and I will never use another cage nut ever again.

If you’re contemplating switching to “Rack Studs”, make the switch today! Much easier installing than conventional rack nuts and screws. Two concerns to be mindful of; one being don’t use a driver for tightening, as these will strip out the philips head of the fastener, and make sure to install the stud properly or you’ll run into spacing issues. Checkout the pics provided here on Amazon and use a philipshead screwdriver and you’ll be set.

These are an absolute must have for any rack mount application. It makes your life so much easier when setting your rack up or just swapping components out.

Great alternative to the old clip/screw method. Much easier and much faster. Only one issue that kept me from giving it 5-stars - be careful if you use a screwdriver, you can snap them without applying much pressure. That is the only weak point I see.

They are really convenient and easy to use just make sure to not overtighten them as i did have a few occasions where i snapped some off maybe a torque screw next time to prevent it?

The red version fits just nicely for my Startech 4U open frame rack; no issues installing it and is very sturdy for a UDMSE and 1U rack shelf. Definitely more convenient and easier than traditional cage nuts especially if you plan to move equipment around frequently or do a lot of testing.

Not sure how to put this but life changing if working with server racks

They are expensive imo but they are great if u swap around often in your racks. Even though they wear out a bit over time

Por fin un sistema para trabajar en racks sin dejarte las uñas y los dedos y pudiendo trabajar uno solo sin ayuda: colocas los cuatro Rackstuds del dispositivo que quieras montar en el rack, insertas el dispositivo y ya sólo tienes apretar las "tuercas" de cierre sin hacer malabarismos sujetando el dispositivo.Ahora ya sólo falta que bajen de precio y adiós a los tradicionales tornillos con tuerca de rack.

these do what they say and are easy to both install and to install the kit on to. SO much better than inserting bloody cage nuts! I do feel it would be easy to over-tighten them, especially for your junior techs. In a static rack in a comms room or data centre, I think these are going to be great! which is of course their intended use.However I was planning on using them in event-based mobile rack cases and sleeves where we are swapping kit in racks all the time, I don't feel they will have the robustness needed for being in a flight case chucked in and out of vans. I'm happy to be proved wrong :)
