M12-1.75 X 170mm 六角頭螺絲 | 316不鏽鋼 | 部分螺紋 (10 / 包)

The hex head grabbed my socket wrench perfectly and the partial threading made alignment on the frame a breeze. These 316s feel rock solid, zero rust worries even in the damp shop air.

Used these to fasten a marine railing bracket where salt spray is constant, and the 316 stainless is holding up perfectly. The partial threading made it easy to get full engagement without bottoming out in the nut.

These bolts are perfect for building a heavy-duty dock anchor I've been working on; the 316 stainless feels extremely durable. The partial threading makes alignment a lot easier than a fully threaded rod would be. They snugged up tight with a socket wrench without any hint of stripping.
