براغي رأس أسطوانية M2-0.4 X 16mm | رأس مسطح محرك سداسي | ملولبة بالكامل | سبائك صلب فئة 12.9 مطلية بالزنك (400/عبوة)

I needed these for a jig I was building and the 12.9 grade alloy steel feels really solid compared to cheaper screws I've used. The 400-count package is great for keeping spares on hand, too.

The hex socket drive on these M2 screws gave me a clean, secure fit when assembling a small jig for my drill press. The zinc plating seems evenly applied, and the flat head sits flush without any burrs. A solid choice for precision work where you don't want to strip the socket.

The 12.9 alloy steel feels properly rigid for M2 hardware, and the zinc plating is even and smooth across all 400 pieces. I’ve used them for jig assembly and they thread cleanly without any binding. Exactly what a precision job needs.
