200 Pcs M4 M5 2020 Series T Nuts, Including 100 Pcs Hex Socket Head Screws, T Slot Nut Hammer Head Fastener Nuts, for 20 Series Aluminum Profile, with 2 Pcs M4 M5 Wrench

Replaced all sorts of missing screws from my 3D printer! It's a lot more firm now!!!

Nothing too crazy about these. The value is good (for how much you get in the pack), and they do their job. Its hardware. I was surprised to see that they are actually stainless steel, so that's a plus.

This set is great. Lots of bolt sizes for various needs. Price is right. Extrusion Rails are my new favorite thing. You can build framing for anything, and it's so strong and easy to buy. And you can print all the trim you'd ever need. SO FUN!

Nice sets of nuts and bolts Good thing there was tape on the plastic box or there would have been nuts and bolts all over the box because there was NO PACKING in the box what-so-ever!! The nuts and bolts were ALL MIXED UP!! I had to take them out and sort pretty much all of them into the right compartments! You’d think they’d take the time to do this so the customer doesn’t have to. But other than those things they seem to be pretty good quality. I took off 1 star because there was no packing and I had to sort them myself.

Needed to add a washer on the bolt to keep it from bottoming out. I’m using a standard right angle brace with 2020 v-slot. But the price was right and had plenty in the kit.

Works

The nuts are the only thing useable in the package. The bolts are so long that if you tighten them down you WILL be buying new extrusion rails. The Allen keys set are noodles at best and cam over and end up destroyed in first use.To use the bolts I will have to clamp them in a vice and grind them to length making dangerous projectiles to embed in my shop wall or eye when the grinder tosses them. I've always wanted a bolt in the eye. Or I could stack a bunch of nasty washers on them to make up for this, not doing it. I am not assembling things wrong because people can't be bothered to properly measure things.MOST EXPENSIVE NUTS I HAVE EVER BOUGHT. $10 for a tiny bag of nuts! Are you really willing to pay $10 for a small bag of tiny nuts? I am not. If you buy these, save time and scoop out the nuts and throw the rest away. No other part of this kit is useable. on your printer, never will be.If I wanted to be grossly overcharged for the wrong sized hardware I have bought local at Fastenal. Totally stalled my build of a printer I really needed to have running in my farm. Now I will have to go pay a $1 a piece for the right bolts locally.You got me once, but you wont get me twice.

The description has 10mm thread length, but they are 12mm. I needed 10mm length. Unless your item to attach to your 2020 extrusion is at least 6mm thick you can't use these with a washer. My application is only 5mm thick. Oh well, I'll keep them in my parts draw.
