براغي رأس مقبس M4-0.7 × 16 مم | محرك مقبس سداسي منخفض الرأس | كاملة الخيوط | فولاذ سبائكي فئة 8.8 (300 / عبوة)

I needed a solid batch of fasteners for a jig I was building, and these M4 screws came fully threaded which made setup quick. The 8.8 alloy steel feels sturdy enough for repeated use in my precision assemblies.

The hex socket drive grips the Allen key perfectly, no stripping even when I torqued them down into aluminum. All 300 came in a sturdy box with threads that look clean and uniform. These are doing a solid job holding my tooling fixture together.

I needed some compact fasteners for a jig I was building, and the socket drive on these M4s let me get them tight in a tight space without stripping. The 16mm length was exactly what I needed for a clean, flush fit.
