Review: Strong, Precise, and Great Value - 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.
