براغي رأس مقبس M5-0.8 × 70 مم | رأس مسطح محرك سداسي | ملولبة جزئيًا | سبيكة فولاذ فئة 12.9 مجلفنة (100 / عبوة)

The partial threading is exactly what I needed for clamping thicker plates without bottoming out, and the zinc finish hasn't shown a speck of rust after a week of assembly work. These M5s drove in smooth with no stripping.

The hex socket drive seated cleanly in my driver without any wobble, and the 12.9 alloy steel held up perfectly when I torqued them into the jig. Zinc plating looks uniform across all 100 pieces, so no rust worries in my shop.

The partially threaded design worked perfectly for clamping two aluminum plates together, and the zinc plating still looks clean after a few weeks in my shop. These 70mm lengths are exactly what I needed for my jig setup, and all 100 arrived with clean threads and no burrs.
