M16-2 X 45mm 內六角螺絲 | 平頭六角驅動 | 全螺紋 | 18/8不鏽鋼 (50 / 包)

Used these for a jig I’m building and the 18/8 stainless really resists rust in my garage. The flat head sits flush perfectly, and the threading was clean all the way down.

The threads are perfectly formed and the 18/8 stainless finish is smooth with no burrs—they seated flush in my jig without any binding. Fifty pieces for this size is a solid value, and the flat head design gives a clean, low-profile look once torqued down.

The hex socket drive gripped my Allen key perfectly without any slippage during assembly, and the fully threaded shaft made adjusting tension on my machining jig incredibly easy. These stainless steel screws feel truly solid for precision work.
