M12-1.75 x 290mm 六角頭螺絲 | 316不鏽鋼 | 部分螺紋（10個/包）

Pulled these out of the box yesterday for a custom bracket project, and the 316 stainless finish is noticeably smoother than typical hardware store bolts. The partial threading made alignment much easier than a fully threaded rod would have been.

Needed these long M12 bolts for a heavy steel bracket assembly, and the 316 stainless build gives me real confidence against rust. The hex head grabbed perfectly with a socket and the partial threading made alignment easy. Happy with the pack quantity too.

These are going back into a marine winch rebuild and the partially threaded section seats perfectly against the flange, no wobble at all. The 316 stainless has that proper dull finish you want for saltwater, and all ten threads were clean and sharp right out of the bag.
