M8-1.25 x 75mm 內六角螺絲 | 內六角驅動 | 部分螺紋 | 316 不鏽鋼 (100/包)

I used these on a marine-grade jig I was building, and the 316 stainless steel held up perfectly against a saltwater spray test. The partially threaded design made alignment much easier than fully threaded screws I’ve tried before.

The hex socket drive grips the allen key perfectly without any stripping, and the 316 stainless steel has that proper marine-grade weight to it. These are going into my jig setup and they threaded in smooth as butter. Exactly what I needed for precision assemblies.

Installed these on a marine railing repair and the 316 stainless is holding up beautifully against the salt spray. The hex socket drive made them easy to tighten even in tight spots.
