150PCS 8 Sizes Copper Metric Sealing Washers Flat Washers Assortment Kit

Kit arrived missing the M14 size, the ones I needed! In its place were more of the M10 size. Sent them back.

Super lot of washers.. I bought a different set but they were all so small. This set gives you a great variety of small and large including ones for typical drain plugs. Highly recommend. Well packaged with Saran Wrap too to keep it from opening!

For the value, this is a great kit! People are complaining about deformities/rough surfaces in the washers when in reality they are just overreacting. The copper is soft and will make a seal after deformation, that is what it's designed to do! Furthermore, there are people that will down vote this washer set on the surface quality when they are most likely using them for oil changes (my true reason for purchase) and they will function as intended, understand what you are purchasing here...150 assorted copper washers for 10$! These aren't OEM and the price isn't paying for a QC inspector to verify every piece. The pictures that someone had with a flat edge, that's unfortunate but that's also the name of the game when considering what you're paying for.If you compare the cost savings to buying crush washers bought at a Big Box store, this is saving you a lot of money! You will pay $1-$2.50 per washer at a box store, that means if you get 10 good washers from this set, its paid for itself!Product packaging:As people said, this is a tiny box. The dividers can slide in slide out, I've already had some of the smaller sizes mix a few times. I think I will glue the dividers in place to prevent this in the future since I like the box to keep everything organized and the size is perfect for a toolbox.In conclusion, the pieces will meet the needs for my, and the general populations, intended use. If doing hydraulic lines I would take more time to inspect every washer I plan to use prior to installing OR pay the extra money for 100% QC products at an auto store.

They may need to be filed a bit around the edges to remove the burr. Other wise they are good. And comparing to car dealer costs and hardware stores you will be happy with them. Oh and the ones I cleaned up measured just fine for parallelism and sealed the joint like they are supposed to.

Great Product! I have purchased four units to monitor our vehicle fleet in Haiti and the service has been phenomenal. Our vehicles have been to some remote places and the units have worked surprisingly well. I have been monitoring our drivers for a month with the purpose of finding out how to cut cost on trips outside the city and I have already come up with ways to save hundreds of dollars a year in per diem and hotel expenses. Because I am able to monitor the vehicles, I spot behaviors that caused some trips that could have been a one day trip to be expended to an overnight one. Our organization works with girls who have been trafficked and sexually exploited. Now, we are able to have an eye on our vehicles when they are transporting survivors. I have also spoken with a Spectrum Tracking representative several times and upon finding out about our work, he offered us a discounted monthly fee. Great product and great customer service!
