M5-0.8 X 12mm ソケットキャップスクリュー | 平頭ヘックスソケットドライブ | 全ねじ | 10.9級合金鋼亜鉛メッキ（900個/袋）

The hex socket drive on these M5 screws makes them much easier to tighten in tight spaces than standard Phillips heads, and the zinc plating gives a clean, corrosion-resistant finish. I used them to rebuild a jig at work and every single one threaded in smoothly without any binding.

Finally, socket cap screws that don't cam out under torque; the hex drive on these is crisp and precise. Every single one threaded cleanly into my steel jig plate without any binding or stripped heads.

I've built quite a few jigs and fixtures with these M5 socket cap screws and the zinc plating has held up great so far. The hex socket drive bites cleanly every time, and having 900 in one package means I never run out mid-project.
