براغي ذات رأس أسطواني M3-0.5 X 14mm | محرك سداسي داخلي | ملولبة بالكامل | فئة 12.9 من سبائك الفولاذ مطلية بالزنك (600/عبوة)

I needed a bulk supply for my CNC jig build, and these M3 cap screws came with consistent threading across the entire pack of 600. The hex drive holds the Allen key firmly without any stripping, even when torqued to spec.

The zinc plating is flawless across all 600 pieces, and the hex socket drive bites cleanly without stripping on my jigs. Threads are uniform with zero burs, so they thread into tapped holes like butter.

I was pleasantly surprised by the consistent thread quality on these M3 screws—every single one seated smoothly without any binding. The zinc plating also feels more even and durable than other bulk fasteners I've used for jigs and fixtures.
