M5-0.8 × 20mm براغي رأس سداسي | فولاذ فئة 8.8 أصفر زنك | ملولبة بالكامل (500 / عبوة)

The yellow zinc coating on these is nicely even, and the 8.8 steel feels sturdy for machine assembly. Used a full bag on a frame project with zero stripped threads.

These hex bolts drove in cleanly with a standard 8mm socket and the yellow zinc coating looks consistent across all 500 pieces. The 20mm length fit perfectly for the jig I was building after stripping some cheaper hardware.

I needed a solid batch of M5 bolts for assembling some jigs, and these hex head screws grab my wrench beautifully without slipping. The yellow zinc finish looks clean and gives me confidence they’ll resist rust in my workshop.
