M12-1.75 X 55mm 內六角螺絲 | 內六角驅動 | 部分螺紋 | 316不鏽鋼 (50顆/包)

Needed some hardware for a custom jig, and these M12-1.75 socket cap screws fit perfectly. The 316 stainless steel feels solid, and the hex drive made installation a breeze.

Installed these on a marine railing project where corrosion resistance was critical, and the 316 stainless steel has held up perfectly against salt spray. The hex socket drive made tightening in tight corners much easier than a regular bolt.

I needed some heavy-duty fasteners for a jig I’m building, and these 316 stainless socket cap screws are exactly what I was looking for—the hex drive makes installation really easy, and the partial threading worked perfectly for my application.
