M16-2 × 45mm براغي رأس مقبس | رأس مسطح محرك مقبس سداسي | ملولبة بالكامل | سبائك فولاذية فئة 12.9 مطلية بالزنك (50 / عبوة)

Installed these in a custom jig and the 12.9 alloy steel feels incredibly strong for the size. The zinc plating looks consistent across all fifty pieces, no rough edges.

The hex socket drive on these M16 screws made quick work of aligning them in my jig setup, and the zinc plating kept them clean through a week of shop dust and oil. Fully threaded along the whole 45mm length, they bit into the fixture with zero stripping. Solid buy for precision assemblies.

I used these on a heavy-duty press tool and the flat head design let me recess them flush without any wobble. The zinc coating seems thicker than other screws I've bought, and each one threaded smoothly all the way down.
