M16-2 X 90mm 육각 소켓 볼트 | 플랫 헤드 육각 소켓 드라이브 | 부분 나사산 | 316 스테인리스 스틸 (25개/팩)

The flat head sits flush with the surface, which was exactly what I needed for a precision jig I’m building. These 316 stainless screws feel solid and resistant to corrosion, and the hex drive made installation a breeze. I’ve already ordered two more packs.

The flat head sits flush perfectly on my jig plate, and the hex socket gripped the Allen key without any wobble. These 316 stainless screws took some serious torque on the partially threaded section, and all 25 arrived with clean threads and no burs.

Finally, M16 hardware that doesn't strip the hex socket under high torque—these flat heads seated perfectly flush in my jig plate. The 316 stainless feels noticeably tougher than standard 304, and the partial threading made alignment a breeze.
