براغي رأس مقبس M16-2 × 180 مم | رأس مسطح بمقبس سداسي | ملولبة جزئيًا | فولاذ سبائكي فئة 12.9 مطلي بالزنك (10 / عبوة)

Used these for a jig build at work and the hex socket drive handled high torque without stripping. The partially threaded design made alignment much easier in tight spots.

The zinc plating looks even and hasn’t chipped during install, which is a relief for a jig that gets constant tightening. The 12.9 grade gives me confidence these won’t stretch under load, and the flat head sits flush like it should. These are the little details that make a build feel solid.

Replaced the old bolts on my press fixture with these and the hex socket drive made installation so much easier. The 12.9 alloy steel feels really sturdy for the price.
