The seller image showed everything politely organized, but I still expected to get a bag of loose hardware. Glad the kit arrived as advertised sorted into labeled adorable baggies.I saw another review complaining the little case didn’t have dividers. As a man of a certain age, you should already have hardware cases and a preexisting sorting method. If this small kit of M6 hardware is all you have, you’ll likely never actually use them anyway. All these baggies are going straight into the M6 section of the machine screw tackle box of my hardware cabinet. If you’re upset the free plastic coming with your hardware doesn’t have certain features, you’ve already failed at whatever project you plan to use them for.

Can't go too wrong with bolts. Great variety. Just what we needed.

A good mixture for any shop. I liked the variety and the handy care

This is a fair assortment of M6 bolts and nuts for various projects. As they are corrosion resistant they should be fine for outdoor use. they are individually packaged which may or may not be useful, at least it helps with not losing them till you get them into your storage system.the 8.8 designation is for structural, with low tensile strength. Meaning it will take very little stress before the bolts stretch so be careful about overthightening these.

This is a very reasonably priced nut and bolt and washer kit. They say grade 8 on them I haven't done any destructive testing on them yet but they don't strip when I put quite a bit of torque on them. Their cadmium plated which is nice because it's corrosion resistant and they're each and nice little bag so you can keep them sorted. There were equal amounts of washers to go along with the nuts and the bolts. I received a fairly small size with a 4 mm thread so they'll work well on small things. The seller also has larger sizes , you just need to determine what you're working on before you order.

This is a nice set of M6 bolts to have around. They come in a plastic holding case with each size packed into individual packs. Since they resist corrosion they are perfect for replacing bolts on the auto, mowers, and garden implements. Each comes with a lock washer to prevent the nut from backing off once tightened. They are handy to have around and I would recommend having this along with a variety of other sized around the tool shed.

The 56PCS Grade 8.8 Metric Bolts and Nuts Assortment Kit is a versatile hardware kit designed to meet various fastening needs, particularly for automotive, mechanical, and general construction projects. This set includes M6 hex bolts in sizes ranging from 12mm to 40mm, all with a yellow zinc plating for enhanced corrosion resistance. Here’s a detailed review:Pros:High-Quality Material (Grade 8.8):The bolts and nuts in this kit are made from Grade 8.8 steel, which is known for its high tensile strength and durability. Grade 8.8 bolts are commonly used in mechanical applications and automotive repairs where reliable performance is essential.Grade 8.8 steel ensures the bolts can withstand significant stress and pressure, making them suitable for demanding tasks.Comprehensive Set:This kit includes 56 pieces with a variety of sizes (ranging from 12mm to 40mm), offering good flexibility for various projects. The set covers a range of lengths, so you can choose the appropriate bolt for different applications without needing to buy individual sizes.It's a great starter kit for DIY enthusiasts, home mechanics, or even professionals who need a wide variety of sizes for different jobs.Yellow Zinc Plating:The yellow zinc plating on the bolts and nuts offers superior corrosion resistance compared to standard steel. This makes the bolts more resistant to rust and oxidation, especially in moist or humid environments.The zinc coating also provides a layer of protection from wear and tear, making the bolts more durable in the long term. This is particularly useful for outdoor projects, automotive applications, or marine environments.Versatile Use:The M6 size is a popular and standard metric size, making this kit suitable for a variety of DIY projects, automotive repairs, home improvement tasks, and even mechanical and industrial applications. It's ideal for assembling furniture, installing equipment, or fixing machinery where M6 bolts are needed.It’s also useful for mounting applications, such as securing parts of cars, bikes, trailers, or machinery.Convenient Storage:The kit comes with a well-organized case that separates the bolts and nuts into different sections based on size. This makes it easy to find the part you need quickly and ensures everything stays organized and accessible.The compact case is also easy to store, so you don’t have to worry about losing any parts in your workshop or garage.Cost-Effective:Purchasing a complete set of bolts and nuts in various sizes is more cost-effective than buying them individually. This kit provides good value for money and saves time compared to searching for individual bolts at hardware stores.Cons:Limited to M6 Size:This kit only includes M6 bolts and nuts, which means it’s not suitable for applications that require other bolt sizes (like M8, M10, or larger). While M6 is a common size, it may not meet the needs of projects requiring larger fasteners, limiting its versatility for certain tasks.No Washers Included:While the set includes bolts and nuts, it does not come with washers, which are often needed for securing fasteners to prevent damage to surfaces or ensure proper load distribution.If you need washers for your application, you’ll need to purchase them separately, which could be inconvenient.Not for Heavy-Duty Applications:While Grade 8.8 steel is strong and durable for most general applications, it may not be suitable for extremely heavy-duty tasks or industrial machinery that requires higher-grade bolts, such as Grade 10.9 or Grade 12.9.For high-stress environments (e.g., construction sites or large machinery), you may need to consider a stronger bolt grade.Plating Wear Over Time:While the yellow zinc plating offers good corrosion resistance initially, it may wear off over time, especially if the bolts are exposed to harsh conditions, like high levels of friction or abrasion. In environments where high durability is essential, you might need to replace bolts more frequently.Conclusion:The 56PCS Grade 8.8 Metric Bolts and Nuts Assortment Kit is an excellent choice for individuals and professionals who need a reliable and versatile set of M6 bolts and nuts for general mechanical, automotive, and DIY applications. The Grade 8.8 steel construction ensures high tensile strength and long-lasting performance, while the yellow zinc plating provides excellent corrosion resistance, making it suitable for use in both indoor and outdoor environments.This kit is particularly useful for home mechanics, DIY enthusiasts, and anyone who frequently works on projects that require metric fasteners. The well-organized storage case and variety of bolt lengths provide convenience, making it easy to find the right part for the job.However, the kit’s limited size range (only M6) and lack of washers may make it unsuitable for users who need bolts of different sizes or for more heavy-duty applications. If you're specifically looking for M6 bolts and nuts and need them for general use, this kit offers good value and is an excellent addition to your toolset.

This is a nifty set of 6mm diameter metric bolts with nuts, flat washers, and split lock washers. The sizes are normal lengths of 12mm, 16mm, 20mm, 25mm, 30mm, 40mm, and 50mm. All the bolts are marked YFN with the exception of the 16mm bolts are marked TBF and the 40mm bolts are marked YN. All the bolts are marked 8.8 but I don't think I would use them in any grade 8 application unless absolutely necessary. There are some markings on the nuts but they are not clear enough to see if they are grade 8 markings or not. The plastic case they came with latches tight but is not waterproof. There are 2 bolts of each length, 14 lock washers, 14 nuts, and 14 flat washers in the kit. I like this mix and would not hesitate to get another set of these as needed for my various projects.
