M16-2 X 45mm 六角頭螺絲 | 316不鏽鋼 | 全螺紋 (25 / 包)

The threading is perfectly clean, so these M16 bolts drove in smoothly with a socket wrench and held a steel bracket rock-solid with zero play. For the price per pack, you're getting proper 316 stainless that won't flash-rust after a few weeks outdoors.

Used these to mount a heavy jig frame on our shop bench and they seated beautifully with a standard socket. The 316 stainless finish is noticeably smoother than the cheap zinc-coated bolts I've dealt with before. Tossed one in the vice to test the threads and they held up without any galling.

The threads are perfectly clean and the 316 stainless steel feels substantial in hand—no burrs or rough edges anywhere. I used them to bolt down a heavy workbench frame and they drove in smoothly with a socket, no stripping at all.
