براغي رأس مقبس M4-0.7 X 30mm | رأس مسطح محرك مقبس سداسي | كامل الخيط | فولاذ مقاوم للصدأ 316 (400 / عبوة)

The hex drive on these 316 stainless screws made assembly much smoother than I expected, and the flat heads sit perfectly flush in the aluminum plate I'm using them on.

Used a full bag of these on a custom jig setup and not a single one stripped during the hex socket drive. The 316 stainless finish feels solidly machined, and the fully threaded length grips perfectly in 30mm depths.

I needed a corrosion-resistant fastener for a saltwater jig, and these 316 stainless screws are holding up perfectly after three months. The 30mm length was exactly what I needed, and the flat head sits flush with the surface for a clean finish. A solid choice for precision assembly work.
