براغي رأس سداسية M4-0.7 × 35 مم | رأس زر بمحرك سداسي | ملولبة بالكامل | فولاذ سبائكي درجة 12.9 مطلي بالزنك (400 / عبوة)

I needed a batch of 400 M4x35mm socket cap screws for a jig build, and the zinc plating on these looks uniform with no burrs right out of the package. They're fully threaded so I could get a solid grip in softer aluminum without stripping. Exactly what you want for precision assemblies.

I needed a bulk pack of M4-0.7 x 35mm socket cap screws for building a jig, and the Class 12.9 alloy steel feels noticeably tougher than the standard ones I've used before. The zinc plating looks consistent across all 400 pieces, no burrs or rough edges.

The hex socket drive on these M4 screws made them a breeze to install in tight spots on a repair fixture. I was impressed with the consistent threading and the zinc coating's smooth finish.
