M16 Stainless Steel Lock Nuts 5pcs 316 Stainless Steel Hex Lock Nylon Insert Nut (5pcs, 316 M16)

What I was looking for and worked great!

It never fails, you don’t have the screw, nut, or bolt you need from your spare bits and bobs bin for that project you’re working on. Or even worse, you have a giant jar of extra bits and have to sort through the mess.Well, here’s your opportunity to get a lifetime supply (for me at least) of M5 nylock nuts. Seriously, I’m not sure the scenario where I will get through all of these nuts.I’m a fan of having things organized by size in containers, so 150 of these M5 bolts scratches that specific itch. The only problem is now you need M3+ and the respective Imperial sizes….As for the product, it came well and simply packaged. Not cheap plastic boxes I’m going to toss anyway. A zip baggie in a box, we’ll taped. Good enough.Quality was good, fit as expected and in spec. Time will tell on durability, but most of these are bolt and forget.Happy collecting!

There is only so much I can say about lock nuts. The threads and all surfaces are well formed so build quality is great. They do appear to be real and good quality stainless steel. The nylon lock piece is well attached to the nut and gives them the friction needed to help them resist loosening due to vibration.I wrench on old VW bugs and busses. These M8 (common threaded) nuts are a pretty common need for me and in certain places I do like to use stainless. These metric sizes are getting hard to find locally and when I do they cost a lot. These are very reasonably priced.

These fit standard M4 bolts and the nylon rings are quite snug so no concerns with these backing off with cyclic loading (I can't screw these on with just my hands, in requires a wrench, that's a tight fit!). For the price, this is a great option for nuts in bulk. Would recommend!

I feel like a squirrel, hoarding my shiny nuts.I've been in dire need for M3 nuts for a while. They are kind of hard to find in brick and mortar stores in my area. You typically have to find a hobby store to find them and when you do, a pack of ten nuts is one quarter the price of a pack of 350 as we have here. The nuts are well made, the threads are clean and thread well onto M3 screws. The nylon insert provides enough resistance to the screw that it will prevent it from becoming loose and backing itself off. Recommended.

Vine review, so keep that in mind.When the family run hardware store near my house closed and was demolished for a new out of town Bank branch, I was forced to look at the big box stores, which have a limited selection, or drive much further to find specialty hardware. I guess the internet is the solution. This is my new go-to vendor and optionmfor this type of specialty hardware. In a pinch, I'll make the longer car trip, but if I can wait 2-3 days, I now order them online. It's kind of sad, but it's my new reality.Boxes are a good value based on number of pieces, though there was some benefit of the old hardware store in being able to buy only the number I need. Oh well. I guess I'll have spares.

Lock nuts seem to be good quality material and function as they should.Mine came is a small case which is nice to keep organized and carry around.Price is a good value.I would purchase again and recommend!

Nuts and bolts are one of those things that should just work, and these do. I didn't experience any issue with the nuts having burrs or other manufacturing defects. The nylon lock was tight and has held the nuts tight on the few pieces I've used them on, although they aren't on high vibrations parts so I can directly speak to their performance there.
