براغي ماكينة M4-0.7 × 40 مم | رأس بان فيليبس | فولاذ مقاوم للصدأ 316 (300 / عبوة)

I needed fasteners that wouldn’t rust on my dock project, and the 316 stainless steel in these feels solidly built. The Phillips drive bites nicely without slipping, and a full box of 300 should last me a while.

The 40mm length is perfect for building a marine railing, and I’m impressed how smoothly the Phillips drive bit seated each one. These 316 stainless screws handled a week of salt spray without a hint of rust, which is exactly what I needed.

I’ve been hunting for non-magnetic fasteners for a sensor housing near a marine pier, and these 316 stainless screws finally ended that search. The 40mm length is perfect for the thicker gaskets I’m using, and the Phillips drive didn’t strip once across all 300 pieces.
