M5 nut, washer, and bolts

These M3 nuts, washers, and bolts were designed in Fusion 360. You can buy them on Amazon here:

Screw Bolts and Nuts Set - M2 M3 M4 M5

M3 Square Nuts

Lock nuts set - M3 M4 M5 M6 M8 M10 M12

I measured them with a digital caliper accurate to 0.01 mm, and 3D modeled them accordingly.

I also have M2, M3, M4, and M5 nuts, washers, and bolts.
