WEGOUP 900-Piece Flat Washer Assortment, 304 Stainless Steel, 9 Sizes

Choosing washers for one repair is different from keeping a range of metric sizes on hand. This WEGOUP assortment is aimed at the second need, with 900 flat washers for screws and bolts.

The set covers M2 through M12 in nine sizes. That spread can be useful for household repairs, furniture work, electrical maintenance, and construction tasks where the fastener size may vary.

The distribution leans heavily toward the smaller sizes: M2 and M2.5 have 210 washers each, while M10 and M12 have 10 each. If your work mainly uses larger washers, the quantities may not match your needs.

The essentials

These are flat washers made from 304 stainless steel, according to the product details. They are intended for use with machine screws and metric bolts, including situations where a washer can help accommodate a bolt that is smaller than the washer opening. The listed thickness is 1 millimeter.

The 900-piece count is divided across M2 (210), M2.5 (210), M3 (200), M4 (110), M5 (80), M6 (42), M8 (28), M10 (10), and M12 (10). This makes the kit more practical for mixed-size jobs than a pack focused on just one size, but it is not an even spread: the smaller washers make up most of the assortment.

Buyers often highlight the range of sizes, usefulness for home and DIY tasks, and the convenience of having washers ready to hand. Feedback on the size mix is less uniform: some appreciate the assortment, while others would prefer fewer very small washers and more of the larger sizes. That distinction matters if you already know which sizes your projects use.

Tips for day-to-day use

The washers come in a clear plastic case with separate compartments and labels for the sizes. Keeping each size in its labeled section can make it easier to identify the right washer during a repair, rather than sorting through a mixed container. The case is described as a storage organizer, no specific care or cleaning instructions are provided.

Before starting a job, match the washer size to the fastener and the opening it needs to sit around. The listed size range is metric, so this assortment is most relevant when your screws or bolts are specified in metric sizes. It does not provide a stated count for every possible task beyond the quantities listed above.

Who it’s for

It suits you if you handle a mix of small repairs and want several metric washer sizes stored together. The assortment may also suit a home workshop where occasional jobs call for different sizes, rather than repeated use of just one washer type. Buyers describe the set as handy for DIY and general household tasks, though those impressions are not a substitute for matching the washer to the fastener in your project.

It’s not for you if you need a large supply of M10 or M12 washers: this kit includes only 10 of each. If you routinely use one specific size, a pack concentrated on that size may fit your work better than a broad assortment with most pieces in the smaller sizes.

When it makes sense

Choose this kit when variety and organized storage are more useful than a uniform quantity of one size. For example, someone handling a furniture repair one day and a small maintenance task another day could draw from the labeled compartments without sourcing each listed size separately. For a project with known, repeated fastener requirements, compare the listed quantities with the job before relying on the assortment. Its strongest fit is mixed, occasional use across the included metric sizes—not a high-volume supply of the largest sizes.
