M3-0.5 × 35mm براغي رأس مقبس | رأس مسطح بمقبس سداسي | خيط جزئي | فئة 10.9 سبيكة فولاذ مطلية بالزنك (600/عبوة)

The zinc plating is holding up nicely on these, and the partially threaded design gives the grip I need for jig assemblies. 600 in the bag means I won’t be running out mid-project, which is exactly what I was hoping for.

The hex socket drive seated my driver bit cleanly on every single one of the 600, and I didn't strip a single head during assembly. The zinc plating gives them a consistent finish that's held up well in my tooling fixtures.

Used a full pack on a custom jig build — the hex socket drive made installation a breeze and the zinc plating held up perfectly. These class 10.9 screws feel solid and precise for any machinery project.
