براغي رأس سداسي M3-0.5 X 20mm | فولاد فئة 8.8 مطلي بالزنك | خيط كامل (600 / عبوة)

The 8.8 steel grade gives me confidence these won't strip under moderate torque, and the zinc plating seems to be holding up fine on outdoor gear. Used a full bag on a conveyor table with no issues so far.

These are my go-to for jigs and fixtures, and the zinc plating has held up nicely without any rust after a few months in my shop. The fully threaded length means I can cut them to size when I need a non-standard depth.

The hex heads grip the socket drive perfectly, and the zinc coating is clean with no burs. These are a solid choice for securing brackets on a machine build I just finished.
