براغي رأس سداسي M3-0.5 × 16 مم | فولاذ درجة 8.8 مطلي بالزنك | كامل الخيط (300/عبوة)

Pulled out a few to check the hex head fit — perfect engagement with my 3mm socket, no wobble. The zinc plating looks even and should hold up well inside a metal enclosure I’m building.

I needed M3 x 16mm screws for a small robotics frame, and the zinc plating on these makes them look clean and resist rust. The fully threaded length was perfect for securing the brackets tightly.

The hex heads grabbed my 5mm socket perfectly with zero stripping, and the Class 8.8 steel feels solid even under a wrench. Packed in a tidy 300-count box, these fully threaded M3s are exactly what I needed for a frame rebuild.
