M16-2 x 80mm 內六角螺絲 | 六角孔驅動 | 部分螺紋 | 316 不鏽鋼 (25 / 包)

The partial threading makes them perfect for clamping down on our jig fixtures without bottoming out prematurely. Machined a test piece and the hex socket seated cleanly every time, zero stripping. These are solidly built for precision work.

Used these for a marine railing repair and the 316 stainless held up perfectly against salt spray. The hex socket drive made installation easy with limited access.

Finally got these in for a tooling fixture I'm building, and the 316 stainless is exactly what I needed for the marine environment it'll sit in. The partially threaded length let me clamp two plates without any shimming fuss, and they torqued down smooth with zero galling on the hex socket.
