120pcs M3 x 6mm Hex Socket Head Cap Screws Bolts, 12.9 Grade Alloy Steel, Black Oxide Finish, Allen Socket Drive, Full Threads,with Hex Spanner

This screw set is excellent quality. The 12.9 grade alloy steel makes them very strong and reliable for heavy-duty applications, and the black oxide finish gives them a clean, professional look while helping to resist rust. The machining is precise—the threads are smooth, consistent, and seat firmly without stripping. I like that they come fully threaded, making them versatile for different projects, from 3D printer assemblies to furniture, robotics, and DIY builds. The Allen socket drive fits snugly with the included hex spanner and standard tools, which prevents rounding out. The 180-piece set is a great value, giving me plenty of screws for current and future projects without having to worry about running out. Everything comes neatly packaged, which keeps the hardware organized and easy to grab. Overall, these are durable, accurate, and dependable screws. Highly recommended for makers, builders, and anyone needing high-strength fasteners

Good quality screws for replacing screws on scope mounts. They are hardened so you don’t have to worry about the head stripping out on them

Item is good and works as described

This is a nice assortment of M5 Allens. worth the price.

I bought the 50mm and 14mm screws. They are of good quality. The 50mm was not threaded to the head, but that didn't affect what I needed them for.

I am unsure if they are M4 might be more like M4.2 or something like that, but! they work fine!

They are excellent quality

Product as described. Works great for 3d printer..
