براغي رأس أسطوانية M10-1.5 × 25 مم | رأس مسطح بمحرك سداسي | ملولبة بالكامل | فولاذ مقاوم للصدأ 316 (100 / عبوة)

For a boat railing repair, the 316 stainless held up perfectly in saltwater spray after a month—no rust at all. The hex drive seated firmly without stripping even with a high-torque wrench.

I’ve been using these screws for a jig fixture I’m building, and the 316 stainless steel feels significantly more corrosion-resistant than the 304 stuff I used before. The flat head sits perfectly flush in the countersunk holes, which really makes the assembly look clean and professional.

Finally, a bolt pack that isn't full of rusted duds—the 316 stainless finish on these feels properly marine-grade. The hex socket drive seated perfectly with my Allen key, no stripping on the first few I've torqued down for a jig build.
