Customer Reviews (4.8 / 5 · 5 reviews)

Steven M. ★★★★★

The black oxide finish on these M3 screws is holding up well on my jig setup, no rust after a few weeks of use. The hex socket drive makes them easy to tighten in tight spots, and the 25mm length is perfect for my needs.

Sebastian ★★★★★

Finally got these for my RC car build and the 12.9 alloy steel handles high torque from the motor mount without stripping. Sits flush with my aluminum parts due to the button head design—perfect for tight clearance spots.

Emily S. ★★★★★

The black oxide finish on these M3 screws looks clean and professional, and they threaded smoothly into my jig fixtures without any binding. For 600 pieces at this quality, it’s a solid deal.
