Review on Mechanical Industry Machinery: Hexagonal Stainless Steel by Aaron Collins

I only needed them for some 3D printing projects with adjustable handles. I didn't need them to be stainless steel, but they were the only screws I needed. At first I thought $17 for screws was a lot. Unfortunately they were delivered a few days late so I decided to go to a hardware store to see if I could find some screws I needed to get started. To my surprise, a 30mm M4 stainless steel screw was $0.80 each at Ace Hardware! So oddly, spending $17 on screws can be a lot worse if you buy them locally. They also had stainless steel alternatives at Ace Hardware for $0.40 for the same size. Even so, at this price point, it will still be more expensive than buying these. Excellent quality screws and casing. This is the most durable case I've ever seen.
