براغي تثبيت رأس كأسي مخروطي M8 × 16 مم | فولاذ مقاوم للصدأ 316 (250/عبوة)

The cup point bites into the shaft firmly, and even after a whole batch of installations, none of them have worked loose. 316 stainless feels solid, and the hex socket drive makes them easy to seat in awkward spots.

The hex socket drive really helped me tighten these into a tight spot on my motorcycle without stripping. The 316 stainless gives me confidence they won't rust out here in the coastal weather. A solid buy for any fastening project needing corrosion resistance.

I ordered these for a marine repair job, and the 316 stainless steel is holding up perfectly against salt spray—no rust at all after a month of exposure. The cup point grips firmly without slipping, even in a tight aluminum bracket.
