Timothy ★★★★★

Used a handful of these on a small robotics project and they held firm even with constant motor vibration. The zinc coating looks clean and the steel feels sturdy enough for repeated use.

Ryan G. ★★★★★

Picked up a 5000-pack for some small electronics enclosures I'm building, and these M3 lock washers grip the threads perfectly without binding. The zinc plating seems consistent across the batch, which is nice for a uniform appearance in the final assembly.

Ryan ★★★★★

The zinc coating on these M3 washers is nice and uniform—they fit perfectly on my small RC car builds without any burrs. Just the right thickness to hold tight under vibration without distorting.
