براغي رأس كبسولة M5-0.8 × 12 مم | رأس زر مع محرك سداسي | ملولبة بالكامل | فولاذ مقاوم للصدأ 316 (400 / عبوة)

I needed corrosion-resistant fasteners for a marine jig, and these 316 stainless screws fit perfectly without any rust worries. The 400-count package is generous, and every one has clean threads that thread smoothly into tapped holes.

Installed these on a marine hatch rebuild where corrosion is always an issue, and the 316 stainless finish looks perfect after a month of salt spray. The hex socket drive seated firmly with no stripping compared to cheaper Phillips heads I've used before.

Used a full pack on a test jig build and every single one threaded in clean without a single stripped head or snapped shaft. The 316 stainless feels properly marine-grade, not the cheap 304 stuff you usually get in bulk packs. For 400 pieces at this price, I'm already ordering another box.
