The flat head sits flush perfectly in my jig fixtures, and the zinc plating looks clean with no rough edges. These 12.9 alloy screws are definitely tougher than the standard ones I've been using.

I needed some high-strength fasteners for a custom jig, and these M16-2 x 20mm screws with the Class 12.9 alloy steel feel incredibly solid. The zinc plating looks clean and uniform, and the hex socket drove in without any cam-out. A perfect fit for my precision assembly.

These hex socket screws fit perfectly into my jig setup, and the flat head sits flush without any wobble. The zinc coating seems durable enough to resist rust in my shop environment.
