براغي رأس مجوفة M12-1.75 × 60 مم | رأس مسطح محرك سداسي مجوف | كامل الخيوط | فولاذ مقاوم للصدأ 316 (50 / عبوة)

I needed some corrosion-resistant fasteners for a marine jig I'm building, and the fully threaded 316 stainless steel on these is perfect for that. The flat head sits flush with the surface, which saved me from having to countersink anything extra.

The hex socket drive seated perfectly on my wrench with zero stripping, even after torquing them down on a jig fixture. The 316 stainless finish is smooth and uniform across all 50 pieces, which I appreciate for outdoor tooling that sees rain.

Got these for a marine repair job where rust was a constant headache, and the 316 stainless is exactly what I needed. The hex socket drive seated perfectly with my driver, and the fully threaded length gave me solid grip through thick brackets.
