Accurate, but covered in black paint dust that gets all over your skin and anything you touch. This badly stained white PETG 3D prints that came in contact.

Not much to say. It's bolts. The black does wear off on your fingers, but i think this is normal

These seem to be good quality M3 x 35 mm screws. The Length is as described, and the screws fit well with the M3 nuts I already had. The set includes an Allen wrench. No complaints whatsoever.

I needed some M3x30mm machine screws for a project, and these were exactly what I was looking for. Initially, I considered buying them from a loc hardware store, but for the same price, I would have only received 14 screws. With this pack, I got 120— that’s 106 more for the same price! I generally prefer to support local stores, but when the value is this significant, it’s hard to pass up. Great quality and an unbeatable price!

These are nice if you need longer M3 bolts, or can cut them down. This specific brand seems well made - no burs or roughness, and it smoothly fits other M3 hardware I have. I have tried other M3 bolts, and like this type the best. The alloy steel hex drive is a lot less likely to slip and strip out. I have also used philips head drive and stainless steel bolts which are much more likely to strip if you need any force.

They are cheap, so don't expect them to be as "nice" as the expensive specialist screws. But they are very functional. Be sure to use a washer with them, I went for a "M3 6mm OD 3mm Black Nylon Gasket Plastic Flat Washer" and it worked great.Happy music making.
