براغي رأس سوكيت M4-0.7 × 4 مم | رأس زرية بمحرك سداسي داخلي | سنون كاملة | فولاذ سبائكي فئة 10.9 مطلي بالزنك (400 / عبوة)

Needed some small, strong fasteners for a jig I was building, and these M4 button heads fit perfectly in the tight spaces. The zinc plating looks clean and even, and they torqued down nicely without any stripping. Exactly what I needed for those precision assemblies.

The hex socket drive fits my Allen wrench perfectly, no wobble or stripping even after multiple installations. These little screws are holding tight on my 3D printer jig just as expected.

I needed a fresh batch of small M4 cap screws for jig assembly, and these 400-piece packs are perfect for not running out mid-project. The hex socket drive feels solid, and the class 10.9 alloy steel gives me confidence they’ll hold up under load.
