براغي رأس أسطواني M4-0.7 X 30mm | محرك سداسي داخلي | ملولبة جزئياً | فئة 8.8 سبيكة فولاذية مطلية بالزنك (400 / عبوة)

Packed 400 to a box, these M4 screws have clean threads that start easily by hand, which made assembly on my jig fixture a breeze. The zinc plating looks uniform and should resist rust well in my shop.

I needed some high-grade fasteners for a jig I was building, and the 400-count package is fantastic value. These M4 screws have a nice, clean zinc finish and the hex socket drive fits my standard Allen key perfectly. The 8.8 rating gives me confidence they'll hold up under repeated use.

The partial thread on these M4 screws makes them perfect for holding panels without bottoming out early. The hex drive seated cleanly in my jig, and the zinc plating looks consistent across all 400 pieces.
