FullerKreg (Pack of 25) M5 x 0.8 DIN 6926 Hex Flange Nylon Insert Lock Nuts, 18-8 Stainless Steel 304, Bright Finish

Flange nuts are great. You can put them in a socket wrench and they don't fall into the socket. That means you can start the nut one-handed. That's crucial for blind applications (where you're reaching around somewhere unseen). Also, you don't really need washers to spread the load out on the fixture. They are the perfect hardware nut.These are also made of stainless, which is great. They won't rust. The price is great, compared to my local hardware store. I find myself replacing all the bolts on my projects with these, and that makes working on them again such a joy. Never rusty and easy assembly. Perfect!

I recently moved house and somewhere in the process misplaced the hardware for my kitchen table. Rather than make yet another trip to the local hardware store (there's a lot of that with a new house), I just ordered these and let them come to me while I tackled other projects.The locking nut + washer combo meant fewer parts were needed than originally came with my table (separate nuts, locking washers, and regular washers). These went on easy enough (would've been easier with a deep socket instead of a wrench, but you work with what you've got). All 10 parts were in the package and nothing appeared to be damaged in shipping.

I bought these as part of a refurbishment of a garden bench. I wanted all stainless steel hardware to avoid issues with rust. These nuts were just right for my application, and the nylon insert will keep them from loosening up over time.

Revising my original review because I found the missing (2) nuts - my bad ;-)(20) Nice Quality Nuts, well finished, packaged in a box that I can store them in.The nylon "locker" holds well to bolts/studs.Would purchase again!

Great for applications on Japanese cars that use these everywhere.And much cheaper when you price them at a dealer.

These are very well machined, high quality fasteners. Will buy again.

Very high quality, perfect fit on a wrench, cut exactly right

I ordered a 20 pack... it came with 16.... seriously!? im sure you can count my money just fine... how come you can not count out the product quantity. i got ripped off... beware!
