M16-2 x 210mm 六角頭螺絲 | 強度等級10.9 鋼材鍍鋅 | 部分螺紋 (10入/包)

The hex head on these M16 screws gives a solid, secure grip with a socket wrench, and the zinc plating already looks tough after a week in a damp shop. I used them to mount a heavy motor bracket, and the partial threading made alignment easier than I expected. They feel sturdier than the standard bo

The partially threaded design made aligning them in tight spots much easier than fully threaded bolts I've used before. The hex head gripped my socket perfectly without slipping, and the zinc plating has a clean, uniform finish. These feel tough enough for heavy equipment assembly.

These bolts have a really solid feel; the Class 10.9 steel makes them feel tougher than what I usually grab. The partially threaded section was just what I needed for a spacer situation on a jig I was building.
