  • M3 Size. 3mm Hole. Measure First.​ Built for 1/8" (3.2mm) pop rivets. Too small for big jobs, perfect for tiny shafts. 35% of returns guess wrong. Match the mandrel size, or it won't fit.
  • 200 Pieces. One Box. No Lost Micro-Parts.​ 200 washers in a dedicated compartment. No torn bags spilling beads everywhere. Lose one? You've got 199 backups.
  • Real 304. No Rust Stains.​ Not aluminum. Not coated steel. Real 18-8 stainless. Shrugs off garage humidity. Use it on electronics; corroded washers kill conductivity.
  • No Burrs. No Scratched PCBs.​ Run your finger over the edge. Smooth. Slide it onto a tiny rivet — no catching, no gouging the workpiece. Deburred before it ships.
  • Electronics. RC Cars. Models.​ PCB grounding. RC chassis repairs. Model builds. Jewelry making. Anywhere a tiny rivet needs a bigger footprint.
