براغي رأس مقبس M12-1.75 × 70 مم | محرك سداسي المقبس مسطح الرأس | ملولبة جزئيًا | فولاذ سبائكي من الفئة 12.9 مطلي بالزنك (50 / عبوة)

The hex socket drive made installation much easier than dealing with standard hex heads. These feel incredibly solid, and the zinc plating looks like it'll resist rust well on the shop bench.

The partial threading is just right for clamping thick brackets without bottoming out, and the 12.9 alloy steel feels reassuringly tough during install. Zinc plating looks clean and even across all 50 pieces, no burrs on the threads either. These are going straight into my jig builds from now on.

I used these M12-1.75 x 70mm socket cap screws for building a jig and the hex socket drive made tightening them really easy, even in tight spots. The flat head sits flush perfectly, and the zinc plating looks clean and durable. Exactly what I needed for precision work.
