M3-0.5 X 5mm براغي رأس كبس بمقبس | محرك سداسي | ملولب بالكامل | فولاذ سبائك فئة 12.9 مطلي بالزنك (900 / عبوة)

The zinc plating on these looks uniform and clean, no flaking or rough edges. I’ve been using them in a precision assembly and the hex socket drive grabs perfectly every time.

Just rebuilt a small jig for my bench and these 12.9 alloy steel screws torqued down without a single stripped head. The zinc plating gives them a clean, uniform finish that fits right into precision work.

The hex socket drive fits perfectly with my allen keys, and the threads are clean all the way through on every single screw from this 900-pack. For the price, you're getting a ton of quality fasteners that feel robust for jigs and small assemblies.
