✅ Internal 22mm 0.866in hole matches standard m22 bolts perfectly
✅ Outer dimension spans 28mm 1.102in to cover bare metal gaps completely
✅ Plate thickness clocks in at 1.5mm 0.059in to brace heavy fasteners

💡 Why do mechanics reach for copper flat washers instead of stainless steel?
Copper handles thermal expansion and voltage flow way better than steel, making it handy for sealing engine blocks and marine rigs.
- Copper stays soft enough to conform to warped bolt heads and seal minor leaks around fluid ports
- The material conducts electricity safely while keeping stray currents away from sensitive wiring harnesses
- Lubricating them during assembly cuts friction and keeps torque readings steady during tight runs
