M16-2 x 25mm 內六角螺絲 | 平頭六角驅動 | 全螺紋 | 12.9級合金鋼 鍍鋅 (50 顆/包)

The flat head on these M16 screws sits perfectly flush in my tooling fixture, and the hex socket drive made installation really easy. The zinc plating looks clean and should hold up well against rust in my shop.

I needed some strong fasteners for a jig I was building, and the fully threaded design of these M16 screws made alignment much easier. The hex socket drive gave a solid grip too, no stripping or slipping.

Installed these in a jig for a production fixture, and the hex socket drive made tightening them in tight spots a breeze. The 12.9 alloy steel feels much tougher than typical hardware store bolts. Exactly what I needed for heavy-duty tooling.
