    Nice set for the home handyman
  

*by W***B on Reviewed in the United States on August 27, 2024*

This is a nice set if you lose or damage a sealing washer while doing repairs. It saves a trip to the store for such an insignificant but necessary part during reassembly.

    Copper crush washer - metric - 150 ct 15 sizes
  

*by D***E on Reviewed in the United States on August 20, 2024*

I bought these hoping they would fit the brake line banjo bolt for my 1973 Yamaha RD350. They did fit, just a little more material. Nothing wrong there.I have not installed these yet, but I do not see any issues. I did take sandpaper to a washer to see if they were coated or actual copper. From sanding, I still see copper. May need to break one in half - but no concerns about them being coated from that assessment.*Mine arrived sorted correctly. Other buyers said the washers became disorganized. It may be they have updated their packaging with that plastic cover (see photo) to help.Will buy again - glad to have many more for future projects.
