300 PCS Copper Sealing Rings Assortment Set, 12 Sizes Copper Metric Flat Sealing Washers Kit, Sump Plug Gasket Crush Washer Assortment, M5 M6 M8 M10 M12 M14 M16 M20

Perfect for working on motor bike break system.

I bought this copper washer assortment set to keep in my garage for general maintenance work, and it’s already come in handy several times. The box includes a nice range of sizes — everything from small M5s to larger M20s — all neatly sorted in individual compartments. The copper quality seems solid; the washers are evenly cut and have a clean surface finish with no burrs or bends. I’ve used a few on brake line fittings and oil drain plugs, and they sealed perfectly without needing to over-tighten. The storage box isn’t the strongest plastic, but it keeps everything organized. For the price, the amount and variety you get makes this kit great value. Pros: 12 common metric sizes, all clearly labeled Good sealing performance and fit Handy to have for car, plumbing, or hydraulic work Cons: Box latch feels a bit flimsy Overall, if you do your own repairs or just like having spare washers on hand, this set is worth it.

Good quality all sizes

Great for the price - handy for the tool cupboard

Handy to have a selection in the tool box reasonable quality used on several jobs already

Excellent selection copper washer in sizes that actually fit modern day vehicles in proper metric sizes no longer having to manage with imperial sized washer which until recently all I seemed to be able to get in large selections

Good value for money, would recommend

I was blown away when I received this box of 'washers'. I don't plan to use them for maintenance, but they will come in very handy for my jewellery making! I TOTALLY love them! I have no doubt that I will be buying more of this product because they are so versatile. The great thing is that there are so many of them of different sizes. Not sure about the plumbing aspect, but for jewellery making I can totally recommend them! Love this purchase!

Impeccable

Todas as unidades com espessura abaixo do anunciado, 1mm e 1,5mm são na realidade 0,85mm e 1,35mm. A medida anunciada M8x13x1 é M8x12x1, tem menos 1mm do diâmetro total. O total de unidades, 300pcs, está correto mas 3 medidas vieram com quantidades erradas, M6x10x1 30pcs(28) -2, M6x12x1 30pcs(31) +1 e M14x18x1 25pcs(26) +1. Caixa de qualidade fraca, chegou tudo misturado com alguns dos separadores a saírem do sítio.
