براغي رأس أسطواني M20-2.5 X 120mm | محرك سداسي داخلي | ملولب جزئيًا | سبيكة فولاذ فئة 12.9 مطلية بالزنك (10 / عبوة)

The hex socket drive on these m20s is machined clean and the zinc plating feels even, no burrs or rough spots out of the package. I used them for a press fixture and the class 12.9 alloy steel held up perfectly under repeated torque.

I needed some heavy-duty screws for a jig I was building, and these M20-2.5 x 120mm cap screws fit the bill perfectly. The Class 12.9 alloy steel feels incredibly solid and the zinc plating looks clean.

The hex socket drive made tightening these into my jig frame effortless, and the partial threads gave just the right grip depth. Fit perfectly with my M20 tapped holes without any wobble.
