براغي رأس سداسية M3-0.5 X 6mm | محرك سداسي برأس زر | خيط كامل | فولاذ سبائكي فئة 12.9 مطلي بالزنك (900/عبوة)

The hex socket drive made it so easy to tighten these M3 screws into my jig without stripping the head. The zinc plating looks clean and uniform across the entire batch of 900.

Finally got around to using these in a small jig I was building and the hex socket drive held up perfectly without stripping under moderate torque. The zinc coating is even and clean, which is nice since they'll be visible in the final assembly.

I needed a bulk supply of small, strong fasteners for some jig builds, and these M3 x 6mm socket cap screws fit the bill perfectly. The hex socket drive bites well without stripping, and the Class 12.9 alloy steel feels reassuringly tough for precision assemblies.
