براغي رأس مقبس M5-0.8 × 10 مم | محرك مقبس سداسي | ملولبة بالكامل | فولاذ سبيكة درجة 12.9 مطلي بالزنك (600/عبوة)

These arrived well-packed and the hex sockets are precisely machined—every one seated perfectly in my drill jig. The 12.9 alloy steel feels noticeably tougher than the standard hardware store stuff.

Picked up a pack of these for some precision assembly work and the 12.9 alloy steel feels noticeably tougher than the standard screws I've used before. The hex socket drive grabs nicely without any stripping, and having 600 in the box is plenty for my current projects.

I needed a solid batch for a jig fixture, and these M5 screws fit perfectly with consistent threading across all 600 pieces. The zinc plating looks uniform and should hold up well in my shop.
