براغي رأس مقبس M6-1 × 40 مم | محرك سداسي مسطح الرأس | ملولبة جزئيًا | فولاذ مقاوم للصدأ 316 (200 / عبوة)

Used a full pack on a marine robotics frame, and the 316 stainless held up perfectly after a week in saltwater. The flat head sits flush without any wobble, exactly what I needed for tight clearance spots.

Got these for a jig I’m building, and the 316 stainless is exactly what I needed for outdoor exposure—no corrosion worries so far. The flat head sits flush nicely, and the partial threading made alignment a breeze. Pack of 200 feels like a solid value for the price.

I needed stronger fasteners for a machinery jig, and these 316 stainless screws handled the torque perfectly without stripping. The partially threaded design made alignment easier than I expected.
