HOLO-KROME 76032 M3-0.5 X 20mm براغي ذات رأس أسطواني بمقبس سداسي | محرك بمقبس سداسي | فولاذ سبائكي مؤكسد أسود حراريًا (100 / عبوة)

I needed a fresh batch for a jig I was putting together and these seated perfectly in the threaded holes without any binding. The hex drive made installation quick with just an Allen key, and the 20mm length was exactly what I needed for a snug fit.

The black oxide finish looks proper and uniform, no flaking even after tightening them into a steel jig with a hex driver. These M3s thread clean every time and the 20mm length is spot on for my precision assembly work.

Finally, a set of M3 screws that actually fit tightly without wobbling. The hex drive seated perfectly with my Wiha bits, and the 20mm length was just right for mounting a new jig plate. These will be my go-to for future precision assemblies.
