براغي ذات رأس تجويف M20-2.5 × 80 مم | رأس مسطح، محرك سداسي | خيط جزئي | فولاذ مقاوم للصدأ 316 (10/عبوة)

The partially threaded section made alignment in my jig a breeze, and the 316 stainless finish looks flawless after a week of salty shop air. Drives clean with a hex key, no stripping on the socket. Just the right mix of grip and corrosion resistance for my precision assemblies.

Installing these on a marine gate, the 316 stainless steel has already held up better than the cheaper zinc-coated ones I used last season. The partial threading is perfect for getting a secure grip without needing a full-length bolt.

The hex socket drive made it easy to tighten these in tight spots on my jig. They fit perfectly and the 316 stainless feels solid and corrosion-resistant. Exactly what I needed for a durable assembly.
