M10-1.5 x 40mm 內六角螺絲 | 六角驅動 | 全螺紋 | 316不鏽鋼 (100顆/包)

Installed these on a saltwater boat railing and the 316 stainless is already proving corrosion resistant after a few weeks in the elements. The hex socket drive made tightening in tight spots much easier than a wrench would have.

These threads cut cleanly into stainless without galling, and the hex socket holds up well to repeated tightening in my jig setup. Pack of 100 should last me quite a while too.

I needed longer fasteners for a saltwater environment project, and these 316 stainless M10s with the hex socket drive threaded in smoothly without any binding. The full threading gave excellent grip in the aluminum frame I was assembling.
