براغي رأس سداسي M18-2.5 X 50mm | فولاذ مقاوم للصدأ 316 | كامل الخيط (25/عبوة)

I was pleasantly surprised by how smoothly the hex head took a socket wrench—no slipping at all. These 316 stainless steel screws are definitely corrosion-resistant enough for outdoor machinery use.

Installed these on a marine railing project and the 316 stainless is already holding up perfectly against the salt spray. The hex head made tightening them with a socket wrench quick and easy.

Finally, a full-threaded M18 that doesn’t strip when I torque it down—the 316 stainless feels tougher than the cheap zinc ones I’ve been replacing. Pack of 25 is plenty for the machine guard rebuild, and the hex heads grab a socket cleanly every time.
