## Questions & Answers

**Q: What kind of plastic are these? pla, abs, or pteg?**
A: PLA, ABS or PTEG ain't going to cut it I'm afraid. While the bags are PTEG, the Rackstuds are made of Grivory, a metal replacement plastic often found in car door handles and wiper blade arms.

**Q: Which version of rackstuds will fit the startech 4u 19" desktop open frame rack?**
A: Sadly the holes on some of the Startech racks are too small for Rackstuds. Search Google for our post on this using Rackstuds and Startech as the keywords. You could try a sample pack that has both sizes/colors to test first if you like.

**Q: are the samples the same quality materials as the actual 100 Pack ? Or they are just guide for figuring out the sizes**
A: Thanks for your question. The samples are production parts and fit for field use. They just contain both sizes/colors along with eight nuts; four in black and four in turquoise so you can determine which size fits your rack best. In saying that, the new Series II Maroon studs fit 70~80% of the rails in the market.

**Q: any reason why I should use the yellow lockwasher?  It's hard for me to get them close together when I use those**
A: Yes, because it's designed to hold the Rackstud in an open position so it doesn't fall through the hole.  Just insert the Rackstud, place the yellow lockwasher on the correct way with the little extra bit facing the rack/Rackstud, mount your gear and then tighten the screw.  It will force the little yellow bit in place.

If you can't tighten it enough by hand use a screwdriver the first time to ensure proper seating of the yellow lockwasher.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Red version fits just nicely for Startech 4U open frame rack
*by P***  on August 15, 2022*

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.

### ⭐⭐⭐⭐⭐ Painless Installation
*by C***  on July 4, 2023*

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.

### ⭐⭐⭐⭐⭐ Good sample pack, if you're not sure if (and which) rack studs will work for you
*by T***N on December 27, 2024*

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.
