Needed these strong bolts and nuts to handle the pressure on snowplow.

I have what feels like an endless project to build a superstrut channel hoist in my attic. These lock nuts were used to ensure I had a safe and secure "lock" on the channel between the superstrut and hanger. So far it has worked great and nothing has backed off which was the intent. The only pro-tip I can offer here is that you definitely want to ensure that if you purchase these you have the proper pitch and size. The thread pitch can result in disaster if it is not the same as the bolt you are using. A matching set of nuts and bolts may be easier for some to avoid this potential issue. 5/5 stars.

Yeah, the nuts eagerly broke out of the plastic clam shell and were looses in the Amazon packaging. But, they were all there and are well made. Great threads and from all visual appearances are well made. Good value. I have a million uses for them On my race car.

We have a fleet of trucks and equipment we're constantly maintaining. When you need a specific nut, or bolt, you'd gladly pay double to have it immediately. We always keep stock for just those occasions. These have been used a few times and have performed just as well as ones coming from our national distributor.

These Grade 8 Coarse Lock Nuts are made from high-strength steel with a yellow zinc finish for corrosion resistance and durability.

These lock nuts offer excellent quality and reliability for anyone needing secure fastening solutions in demanding environments. A great choice for both professional and DIY use!

These are very nice and work great. I have lawn mower deck where the nuts were vibrating off the bolts and these resolved that problem very nicely. The packaging is not good, as the plastic had broken and the nuts were rattling freely inside the box, but at least none were missing.

These nuts are a good fit, easy to spin on and wrench fits well. Finish is great too.
