Customer Reviews (4.8 / 5 · 5 reviews)

Michael X. ★★★★★

Finally got a proper supply of M3 hardware that doesn’t strip when I torque it down—the Class 8.8 zinc plating holds up well on my jig builds. Fully threaded 12mm length made them perfect for securing brackets without hunting for spacers.

Owen ★★★★★

Got these for a bracket assembly job and the hex heads grabbed my wrench perfectly, no stripping even at torque. The zinc coating’s held up fine so far, and the 600 count means I’ve got spares for the next project.

John A. ★★★★★

These M3 screws fit my small RC car chassis perfectly, the hex head makes them easy to drive in tight spots. The zinc plating looks clean and professional once installed.
