M18-2.5 X 40mm براغي رأس سداسي | فولاذ مقاوم للصدأ 316 | سن كامل (25 / عبوة)

Replaced the cheap bolts on my boat trailer with these, and the 316 stainless is already proving itself against the constant salt spray. The hex head gives a solid grip with a socket, making installation quick. They’re pricier, but the corrosion resistance is worth every cent for marine use.

Used a few of these on a saltwater dock repair and the 316 stainless shows no signs of corrosion after a month. The hex heads held up fine under a socket wrench without stripping.

The threads are clean and consistent across all 25 screws, which made installing them into my equipment frame a smooth process. The hex heads hold a socket perfectly without slipping.
