براغي رأس مقبس M4-0.7 × 16 مم | رأس مسطح محرك سداسي المقبس | ملولبة بالكامل | فولاذ سبيكة كلاس 12.9 مطلي بالزنك (600/عبوة)

These are the first M4 screws I've gotten that actually hold up to repeated torque without stripping the hex socket. The zinc plating looks consistent across all 600 pieces, and the flat heads sit perfectly flush in my fixture plates.

The hex drive on these M4 screws grips the driver perfectly without any cam-out, even when tightening into steel jigs. They're the exact 16mm length I needed for assembling my new work fixture, and the zinc plating has held up well so far.

These flat head screws are perfect for the jigs I’ve been building, and the hex drive made installation a breeze with no slipping. The zinc plating looks solid and should hold up well in my shop.
