Goos set to have around teh garage
Good set too have available in the garage and I use them as my "get me out of trouble' set however when doing car brakes or sump plugs I dont rely on these as they are only 1mm thick. However that's no fault as that is the description of the product.

Great Quality and Excellent Value! I’m really impressed with this 1100-piece flat washer assortment kit. The 304 stainless steel feels strong and durable — no rusting or bending like cheaper sets I’ve tried before. The variety of sizes (M2–M12) makes it perfect for all kinds of projects around the house, garage, and even light automotive work. The case is well organized, and each compartment is clearly labeled, which makes finding the right washer super easy. Overall, this set offers fantastic quality and value for the price. Definitely a must-have for anyone who works with screws and bolts regularly. Highly recommend!
