براغي رأس كبس M4-0.7 × 30 مم | رأس زر محرك مقبس سداسي | ملولب بالكامل | فولاذ سبائكي فئة 12.9 مطلي بالزنك (400 / عبوة)

The hex drive seated perfectly in my driver bit without any cam-out, and the 12.9 alloy steel feels noticeably tougher than the usual hardware store screws. These M4-0.7 x 30mm button heads are working great for securing fixture clamps on my milling table.

I needed a bunch of strong fasteners for a jig I was building, and these 12.9 alloy steel screws have way more bite than the cheaper ones I’ve used before. The zinc plating looks even and should hold up fine in my shop.

I needed a solid batch for some jig repairs and these M4 socket caps did the job without any stripped heads. The 12.9 alloy steel feels strong, and the zinc coating seems to resist rust so far. Only wish they came in smaller quantities, but 400 is good value for heavy use.
