All items came in a small plastic case with no dividers. The case secured close easily and contained all items well. The top was marked as to its contents on top but not inside. Bolts, washers and nuts were free from burs or defects and threaded easily. You get 15 each of the bolt, nut, flat washer and lock washer. This is a great deal as typically at my local hardware store each set would be around $2 or more. The flat washer are contained in a reselable bag as are the lock washers. Nice way to keep them from being lost even though the plastic ontainer is adequate.

These will hold your stuff together. Handy around the workshop. Nice that it comes with flat & spring washers.

Fit together very well, convenient to have nuts washers and screws in one package. Use 1/2" socket wrench on both the screws and nuts of this M8 set, even though it is metric. M13 socket works, but is a little loose.

I would have paid close to double what these cost at ace hardware. If you know your size, just order them and have extra. Everything works as it should for 1/2 the price.

You will get 25 complete hex head bolt “Kits” in this package. Each one consists of 1-M6-1.0 x 25mm bolt with matching size fender washer, lock washer and nut. The 13.8mm bolt head is flanged with serrated ribs to help hold them in place on whatever they are attached to. I always check everything that claims to be made of 304 Stainless Steel with a magnet. These definitely passed the test. However, they are still ever so slightly magnetic, because in certain manufacturing conditions such as welding, cold working or different variations of the Chromium & Nickel mixture etc…. This can happen and still prove that it is 304 Stainless Steel as claimed in the listing. Life is Good!! These 304 Stainless Steel Bolt Kits Rate High on the Claydog Approval Scale!! Enough Said, Wrench Drop!! Thanks for your time, Claydog

In an effort to get my hardware stocked back for future projects, I picked up this M6 hardware set. The finish is good upon inspection, with no burs or rough edges. The threads on both the bolts and nuts are clean and burr-free allowing smooth thread engagement. The washers are appropriately sized for these bolts.I've sacrificed a couple of pieces to do some stress testing and while not ultimately scientific, I was able to tighten these well beyond what is advisable, and I didn't have any issues with galling or thread deformation.Overall I'm pleased with this hardware and have no reservations about using it on any of my projects.

These are serrated so that they are good for mounting solar panels to racking as they will "bite" into the metals so that they will electrically bond together.

The hex shape allows for easy tightening using a wrench or socket, offering good torque and a secure fit.Flat and Spring Lock Washers:The inclusion of flat washers helps distribute the load evenly across the surface, preventing damage to the workpiece. Spring lock washers are included to provide added security, ensuring that the fasteners don’t loosen over time due to vibrations or movement. This is especially important for mechanical or automotive applications where constant vibration is present.Fully Threaded Bolts:The bolts in this kit are fully threaded, which allows for greater versatility in applications where you may need to adjust the length or tension. Fully threaded bolts are commonly used in mechanical and industrial settings where more precise adjustments are necessary.Convenient Storage:The bolts, nuts, and washers come organized in a plastic storage case, making it easy to store and access the fasteners. The storage box keeps all the components neatly separated and clearly labeled, saving time during projects and preventing the loss of parts.Performance:Strength and Durability: The 18-8 stainless steel used in these fasteners offers excellent strength and corrosion resistance. The bolts, nuts, and washers can handle typical mechanical loads and stresses, making them suitable for medium-duty tasks. The corrosion resistance of 18-8 stainless steel also ensures longevity, even in outdoor or wet environments, preventing rust and degradation over time.Ease of Use: The flanged hex head bolts are designed for easy installation with standard wrenches or sockets, making the tightening process simple. The flat washers and spring lock washers ensure that the fasteners stay securely in place without loosening, even under vibration. The organized storage case makes it easy to locate the specific fasteners you need without sorting through a disorganized mess.Vibration Resistance: The inclusion of spring lock washers provides added security by preventing bolts from loosening due to vibrations. This is especially useful for automotive, machinery, or construction projects where frequent movement or vibrations could cause conventional fasteners to fail over time.Versatility: The M8-1.25 thread size makes these fasteners suitable for a wide range of applications, from car repairs and home improvement projects to mechanical assemblies and furniture repairs. The variety of washers (flat and lock) also adds versatility, allowing the fasteners to be used in different materials and conditions.Pros:18-8 stainless steel provides excellent corrosion resistance, ideal for both indoor and outdoor use.Flanged hex head design helps distribute load evenly and prevents pulling through soft materials.Includes both flat washers and spring lock washers, ensuring secure fastening and load distribution.Fully threaded bolts offer versatility for adjusting tension or length in various applications.15 complete sets provide plenty of fasteners for a wide range of projects.Comes in a compact, organized storage box, making it easy to access and store components.Affordable and practical solution for DIY, automotive, and light industrial applications.Cons:Limited quantity: The kit contains only 15 sets, which may not be enough for larger projects or frequent use.M8 size limitation: While M8 is a common size, this kit may not be suitable for projects that require different thread sizes.No locking nuts: The kit includes spring lock washers, but does not contain nylon insert locking nuts, which some applications may require for extra security.Conclusion:The Yinpecly 15 Sets M8-1.25 x 20mm Flanged Hex Head Bolts Kit is a solid and versatile fastener assortment made from high-quality 18-8 stainless steel.
