## Customer Reviews

### ⭐⭐⭐⭐⭐ Ps5
*by C***N on October 30, 2024*

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.

### ⭐⭐⭐⭐⭐ Covers a lot of sizes
*by D***N on April 21, 2024*

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

### ⭐⭐⭐⭐⭐ Every Length of M3 Hex Socket Head Cap Screw You Will Probably Ever Need in the Future
*by R***M on March 15, 2024*

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.
