Lots of sizes
I only needed two, but ended up useing this kit 3 more times. I will be needing it for another vehicle soon. Worth the price, and it sure is handy having them in the shop already.

Wide Range of sizes
This Sealing Washers Assortment Set is a great addition to any toolbox. Having a wide range of sizes ensures I’m always prepared for different projects. The quality of the washers is solid, and they work perfectly for sealing purposes. Highly recommend this set for anyone needing reliable washers.

Good Quality Copper Washers
Great quality for use on auto oil drain plugs. Good value n quality. Replaced power-steering that was leaking with 1 copper washer on each side of pressure line. Thumbs up!

Copper crush washer - metric - 150 ct 15 sizes
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.

Annoying assortment
If you spend a decent amount of time around vehicles you'll realize this kit only offers a few sizes that are actually used: 12 and 14. And you'll quickly use those up and realize that some of the other 12 and 14mm sizes are the ones that are way too small in OD. You could use them, but it wouldn't be proper as they wouldn't support the washer-head of the bolt enough. Then there's the weird sizes: 15? 16? 16.5? 17.5? Then it's maddening that there's no 18?! Basically, you buy this kit thinking it'll have the sizes you need, and then after a while you realize there are lots of sizes that simply don't get used, and also the lack of 18mm is no good. If you want this for automotive use I would NOT recommend it.
