M8-1.25 X 140mm 內六角螺絲 | 六角驅動 | 部分螺紋 | 316不鏽鋼 (25入/包)

Installed these in a marine-grade jig I’ve been building, and the 316 stainless material held up perfectly against salt spray during testing. The hex socket drive made torquing them down quick, even in tight spots. Exactly what I needed for a corrosive environment.

The partial threading on these M8 screws made aligning them in my jig much easier than fully threaded ones would have. Used them to replace some rusty bolts on a saltwater dock fixture—the 316 stainless seems rock solid against corrosion.

Was pleasantly surprised by the precision of the threading—they seated perfectly in my jig without any binding. The 316 stainless also feels noticeably more corrosion-resistant than the cheaper hardware I've used before.
