Good sample pack, if you're not sure if (and which) rack studs will work for you

I ordered the small version of this item, providing 4 rack studs each of the red and the purple ones. The red rack studs are meant to be used in racks with steel up to 2.2mm thick, while the purple ones are for thicker racks.This item gave me a perfect opportunity to try rack studs out and see, which version of the studs would work with my StarTech rack. (That rack has steel of 2mm thickness, so - as expected - the red studs were the ones, since the purple ones just sat too lose in the rack.) That gave me the confidence to order a large pack of the red rack studs for my rack (listed as a separate item on amazon).I am really please that Rackstuds provides such a sample pack. If you're unsure, if Rackstuds are for you, this item will provide the answer.

Great test bag

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

Painless Installation

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.

Great Product

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.

This is my new favorite product

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.

Do Their Job

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?

Must have

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.
