M12-1.75 X 80mm 內六角螺絲 | 平頭六角驅動 | 部分螺紋 | 316不鏽鋼 (50入/包)

Used these on a marine railing repair and the 316 stainless is holding up perfectly against the salt spray. The flat head sits flush just as I needed, and the hex drive made installation a breeze even in tight spots.

Finally, a socket cap screw that doesn't rust after a season outside—the 316 stainless is the real deal. The partial threading gave me just enough grip for my jig setup, and the flat head sat flush without any wobble. Pack of 50 means I've got spares for the next project.

The hex socket drive seated perfectly on my driver without any wobble, and the partially threaded length gave just the right grip for a jig I was assembling. Threads cut clean and the 316 finish looks solid for the shop environment.
