M12-1.75 X 40mm 六角頭螺絲 | 316不鏽鋼 | 全螺紋 (50個/包)

The threading is clean and uniform on every single bolt, so they seated perfectly without any cross-threading. I’ve used about thirty of them so far and not one has stripped or corroded, which is exactly what I needed for outdoor equipment.

Finally, a set of hex bolts that don't rust after a single rain—these 316 stainless screws held up perfectly on my boat trailer. The fully threaded shaft made it easy to get a tight fit with a socket wrench.

Used a few of these to secure some outdoor equipment brackets; the 316 stainless seems solid and the fully-threaded shaft made alignment easy. Only wish the pack had a few more extras, but for 50 pieces the price is fair.
