booborny BNW-988 Metric Bolt Assortment, Grade 8.8, M4–M8, Yellow Zinc
Product description
M4, M5, M6, and M8 sizes make this 988-piece metric assortment relevant when a repair or build may call for several common fastener sizes. The bolts are Grade 8.8 alloy steel with yellow zinc plating, and the listed lengths range from 12–30 mm. Bolts, nuts, and washers are stored in a divided carrying case.
If you handle varied jobs, having several sizes together offers a different approach from buying one specified fastener at a time. For a project with a fixed parts list, matching each required size and length remains important.
Technical overview
- Name: booborny BNW-988 Metric Bolt Assortment
- Type: Metric bolt, nut, and washer kit
- Size: M4, M5, M6, and M8
- Material: Grade 8.8 alloy steel bolts

The main buying detail is the range: the assortment covers four metric sizes, while the stated bolt lengths span 12–30 mm. That can be useful for general repairs, machinery work, furniture building, or outdoor construction when the required fastener is among the included sizes. The description identifies the bolts as Grade 8.8 alloy steel, it does not specify a separate grade for the nuts or washers.
Best use cases
This kit is aimed at keeping a mixed supply of metric fasteners on hand for jobs such as home repairs, automotive repairs, and building projects. You’ll appreciate it if your work varies from one task to the next and you want bolts, nuts, and washers in several sizes stored together. The yellow zinc coating is described as corrosion-resistant and intended for outdoor applications, including settings exposed to moisture, that is useful context, but it is not a promise of protection in every environment.
A compartmented assortment is more suited to repeated, varied tasks than a purchase limited to one exact bolt size. By contrast, if a repair calls for a specific fastener outside M4, M5, M6, or M8—or a length outside the listed range—you would need to source that part separately. It’s not for you if your project depends on a size or specification this kit does not list.
Getting the most from it
The case has 20 compartments, with grid markings and labeled sizes to help identify and return pieces to their sections. Its portable format suits moving between a workbench and another job location. Before starting a repair, match the required metric size and bolt length to the part being replaced, then keep the associated nuts and washers together as you work. The listed case dimensions can also help you judge whether it fits your storage space.
For a routine repair, for example, the assortment can provide a way to check several included sizes without keeping separate containers for each one. The most useful fit is a project that needs variety and organized storage, rather than a single uncommon specification.
Before you decide
Which sizes are included? The listed metric sizes are M4, M5, M6, and M8, with bolt lengths from 12–30 mm.
Does the assortment include washers and nuts? Yes. The stated contents include bolts, nuts, and washers, totaling 988 pieces.
What is the coating? The bolts have yellow zinc plating, described as corrosion-resistant for outdoor applications. The listing does not provide a specific service-life rating or environmental limit.
Is it worth it?
This assortment makes the most sense when you regularly encounter different metric fastener needs and value having the parts grouped in a portable case. Its Grade 8.8 alloy steel bolts, four listed sizes, and yellow zinc finish give you concrete details to compare against a job’s requirements. Choose it for general repairs or projects that match those specifications, for a repair requiring a precisely defined size, length, or other specification not listed here, a targeted fastener purchase is the more direct fit.
