M22-2.5 x 140mm 六角頭螺絲 | 316 不鏽鋼 | 全牙 (5 / 包)

Put these on a heavy piece of farm equipment that had stripped threads, and the fully threaded length let me use just enough to get a solid bite. The 316 stainless seems to have a bit more corrosion resistance than the old carbon steel ones I replaced.

These bolts went in smoothly with a socket on my gearbox mount, and the 316 stainless won't rust in the salt air. Much better than the cheap zinc-plated ones I was using.

Finally got around to replacing the old bolts on our dock ramp – the fully threaded design on these made alignment a breeze, and the 316 stainless feels rock solid. They cinched down evenly with a socket, no stripping or binding. Exactly what I needed for a heavy-duty marine fix.
