M2-0.4 X 10mm マシンネジ | なべ頭プラスドライブ | 316ステンレス鋼 (1,000個/袋)

I used a handful to replace corroded fasteners on a stainless steel boat railing, and the 316 stainless held up perfectly in the salt spray. The Phillips drive seated cleanly without stripping, even with the tiny M2 head. These are exactly what you need for marine or outdoor work.

These little screws worked perfectly for a small robotics project I’m building; the pan head sits flush and the Phillips drive didn’t strip once. For 1,000 pieces in 316 stainless, the price is hard to beat, especially knowing they’ll resist any moisture.

I was replacing the hardware on a saltwater aquarium stand and these screws haven't shown a hint of rust after three months of humidity. The 316 stainless steel really does hold up in damp conditions.
