420pcs M3 Screw Kit, Premium Hex Socket Head Cap Screw Assortment with Nuts and Washers, M3x6mm /8mm /10mm /12mm /16mm /20mm /25mm (Silver)

Bought to attach my ps5 to a 3rd party stand. Needed a longer screw because of how my custom plates sat in the stand base.

Got this for a small screw to complete a 3D printing I made for responding filament. It was just what I needed.

This kit consists of the full range of M3 Hex Socket Head Cap Screws with nuts and washers normally needed. Rarely would you need a length outside the 6-25 mm in this kit. A 2.5 mm hex wrench is used for tightening/loosening the hex head while a 5.5 mm wrench is used for the nuts. Unless you have a specific reason, “Socket Head” should be ordered over “Button Head”. This is because the hex socket is deeper which lessens the chance of rounding out the head when tightening. Labeling of the parts box is much better than other parts boxes I have. Both the top and inside of the lid are labeled. This makes it easier to find this box among others you have. The inside label shows you what sizes are in what compartment when the lid is open. This kit was a great addition to my collection of parts kits. I like to immediately have the size I need when working on a project.

I found this M3 socket head bolt set very complete. It contains most of the common sizes that I need. I really enjoy having the sizing label on both the outside and inside of the box. This makes it easy to identify what head size is without having to constantly flip the lid open and closed. The vendor supplies the hardware in a very sturdy box. The compartments are tall enough to prevent each size from overflowing into the other. If you have not used socket head bolts before I highly recommend them. It allows you to use bolts in tight places normal button head bolts do not work in.

I go through a million M3 screws a month on various projects as a hobbyist. I literally just pick the first thing that pops up when searching for these with next day delivery. These are great, all super smooth and machined well. The dimensions are accurate and they came well packaged without random screws mixed in everywhere in the case.

Well, it's hard to have much to say about things that basically either work or not, but these 'just work'. The price is right, and the plastic case is more than adequate. No complaints!

I needed a few different lengths of M3 screws and this kit fit the bill. No issues with them, I will be using this kit again, I'm sure.
