براغي سوكيت M4-0.7 X 70mm | محرك سوكيت سداسي | خيط جزئي | فولاد سبائكي فئة 12.9 مطلي بالزنك (200 / عبوة)

The 70mm length on these M4 screws is perfect for reaching through thicker jig plates where shorter bolts just won't work. The class 12.9 alloy steel feels incredibly tough compared to the usual 8.8 stuff I've used before.

These are exactly what I needed for my jig build—the 70mm length gives plenty of reach, and the partial threading makes alignment a breeze. The zinc plating on all 200 looks uniform, and I didn’t find a single dud in the pack.

The hex socket drive grips the Allen key securely, so there’s no stripping even when I’m torquing them into aluminum. Threads cut clean and the zinc coating has held up fine in my shop for a few weeks now.
