These are either mislabeled or an error as I received 5/16-18 instead of 1/4-20. Otherwise they were solid.

I needed these to finish building a hardware attachment portion of a machine I am putting together and these were exactly what I wanted.The quality of them is great, and I have yet to use one that had any issues, which is better than I can say for the last bag I bought from somewhere else. I also used some to replace some flat ones I had on my 3D printer gantry I built last year, and they are so much more solid feeling when everything is put together.Great product, definitely an upgrade from those old flat cheapy versions!

The spring loaded ball allows for easy setup movement. The t-nut fits great in my track. The stability during set up is also good. Perfect for my operation.

Because these have a spring-loaded ball bearing in them they stay nice and snug in the t-track. Well made and a good quantity for the price.
