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

I purchased this set to use with my single engine aircraft. The washers are good quality and fit perfectly for my application. They may be slightly thin for some applications, so make sure that measurements will work for you. Since I replaced them every time I loosen the plugs, durability is not an issue for me.

These crush washers seem to be good quality and have useful sizes. Most of the sets I saw had a ton of tiny washers I'd never use. This has a significant number of the larger ones. Using them for fuel and brake fittings along with drain plugs.

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.

I buy for be ready incase i needed it think is good

I had to cut a 20mm to check for copper plating. Solid copper. Very happy with this size selection. I now have enough copper washers for the rest of my life!

Wide selection, have already used on my compressor oil plug to stop a annoying oil leak and also used to replace on truck oil pan when I changed oil.

Used to make copper rings. Works well. Very thick so some are hard to hammer but I like the larger sizes.

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