Work good for me

Worked

Good quality

Just what I needed. I purchased some solar panel adjustable mounting frames and appeared to have either was missing 2 sets of hardware or they were misplaced. The mfr didn't sell replacements.

I used these M8 split lock washers on my lawn mower knobs, which usually loosen from vibration, and they stayed firmly in place. Every washer was uniform in size and neatly made. The 304 stainless steel gives them a smooth finish and good rust resistance, with just a light magnetic pull. They came in a small plastic container with a secure lid, well‑protected inside a sturdy box. Compared with other washers I’ve used, these feel more durable and ideal for projects where vibration is a problem like mower parts, deck screws, or outdoor hardware.

Great value and quality. Arrived on time and worked perfect for my project.

Upon receiving this small set of M8 lock washers, I put them through a couple of quick tests and inspections... - Slightly acidic tap water left on the surface of the washers overnight, and refreshed in the mornings for four days in a row, did not leave any surface rust on these washers. - A cursory inspection with calipers showed that these lock washers are dimensionally accurate to the image included in their product listing. - The washers are properly finished, as they had no jaggy, sharp, or unfinished edges. They have a uniform, smooth surface finish, with no burrs, and they would be suitable to be employed on products with exposed hardware. - The washers are slightly magnetic, which is normal for 304 stainless steel that has been cold-worked and formed to shape. - The product listing states that the set would have 40 lock washers, and that is exacly how many were in the package that I received. They are touch-safe, and presented no hazards to bare skin. - The included storage box is reusable, and sized appropriately for the washers that it holds. The box latches shut, so I will not have lock washers bouncing about in my tool box. These washers were delivered exactly as they were shown in the images, and as specified in their Amazon product listing. I am impressed with Neprift brand too, because these were priced 20% lower than they are at my nearest home improvement store.
