براغي رأس سداسي M10-1.5 × 280 مم | فولاذ مقاوم للصدأ 316 | ملولبة جزئيًا (10/عبوة)

These bolts are solid—the 316 stainless steel feels much heavier and more corrosion-resistant than the zinc-plated ones I’ve used before. The partial threading made it easy to seat them deep into a steel bracket without binding.

I was a little worried the 280mm length would be too long for my setup, but the partial threading made it perfect for bolting through a thick bracket. These hex heads grabbed firmly with my socket, and the 316 stainless feels solid enough for outdoor use.

The 316 stainless steel on these M10 screws feels noticeably sturdier than the regular steel ones I've used before, and the partial threading made alignment easier on my equipment. They drove in cleanly with a socket wrench and held tight without any stripping.
