براغي ضبط بنقطة كوب M12 × 45 مم | فولاذ مقاوم للصدأ 316 (50 / عبوة)

I was a bit worried about corrosion in a marine environment, but these 316 stainless set screws have held up perfectly so far. The cup point really digs in and keeps things secure, even with the hex drive torqued down tight.

Used a pack to secure a heavy-duty conveyor guard, and the 316 stainless held up perfectly in a damp environment. The cup point bit into the metal nicely without stripping, even with repeated adjustments.

The hex socket drive made tightening these into tight corners a breeze, and the 316 stainless feels solid enough for outdoor use. My deck project finally has consistent, corrosion-proof fasteners.
