Christopher O. ★★★★★

I needed exact M3-0.5 threads for a plastic injection mold repair, and these Class 8.8 steel screws are perfectly formed with no burrs. The zinc plating gives them a nice, consistent finish that resists light corrosion.

Henry ★★★★★

My cordless driver grabbed these hex heads perfectly without stripping, and the zinc coating looks clean and uniform across all 500 pieces. The fully threaded 6mm length seated flush in my 3D printer carriage plates, exactly what I needed for that job.

Sophia ★★★★★

Finally, a bulk pack of M3 screws that are actually class 8.8 and not some softer grade. The zinc plating on these seems even and hasn't chipped during installation with a hex driver. Perfect for a bunch of small machine guard fasteners I needed.
