M2-0.4×6mm ソケットキャップスクリュー | 六角ドライブ | 全ねじ | 316ステンレス鋼 (600本/パック)

I was pleasantly surprised by the precise fit of these M2 screws in my 3D printer’s aluminum bed—the 316 stainless steel feels much more robust than the zinc-plated ones I've used. They drove in smoothly with a hex key and didn't bind at all during assembly.

I've used cheaper stainless screws before and they'd strip or corrode, but these 316s feel far more solid and the hex drive grabs cleanly every time. The 600 count means I've got plenty for my jigs and tooling for a long while. Exactly what precision assemblies need.

Pulling these out of the package, the hex socket drive felt precise and well-machined. Used a handful to secure a small assembly, and the fully threaded 316 stainless steel gives me confidence they won't corrode. They seated perfectly without any stripping.
