براغي رأس سداسي M20-2.5 X 100mm | فولاذ مقاوم للصدأ 316 | ملولب بالكامل (10 / عبوة)

Installed these on a marine hatch after the old ones rusted out—the 316 stainless is noticeably tougher than standard steel. Fully threaded design made it easy to get a snug fit with a socket. Arrived clean and well-packaged, no complaints.

These were a perfect fit for mounting some heavy brackets in a damp environment — the fully threaded length gives plenty of grip. The hex head grabbed nicely with my socket wrench without any stripping.

The hex head took a 30mm socket perfectly, which made tightening them on a heavy-duty frame much easier. For M20 bolts, the 316 stainless feels robust and corrosion-resistant. Only wish they came in a slightly larger pack for bigger projects.
