50 Pcs M3 x 35mm Thread Pitch 0.5 mm Alloy Steel 12.9 Grade Hex Socket Head Cap Screws Bolts Kit, Black Oxide Finish

I purchased the 100-pack of iexcell M3 x 25mm 12.9 Grade Hex Socket Head Cap screws for a 3D printer build, and I am highly impressed. The 12.9 Grade alloy steel is visibly strong and durable, holding up perfectly against high torque without stripping the hex socket—a common issue with lower-grade hardware. The threading (0.5 mm pitch) is clean and consistent across all screws, ensuring smooth and secure installation. They arrived well-packaged, and the count was accurate. Great value for high-strength metric hardware. Highly recommended for hobbyists and professionals needing reliable M3 screws.

Worked great for my project.

Great value. Good quality. Trying to pick up something like this at your big box or hardware store will cost you twice as much for half the quantity.

Work fine in my karting application. Kind of a difficult size/length to find

Everything good
