These 1/4-20 threaded steel roll-in T-nuts with ball springs are exactly what I needed. Made from durable 1045 steel with a rust-resistant zinc finish, they work perfectly for my 3D printer and CNC router setup. The ball spring allows for easy vertical positioning, and the nuts slide smoothly into the T-slot extrusions without any issues. They fit perfectly with 1010, 1020, and 2020 aluminum extrusions. Installation is simple and reliable. Overall, it’s a high-quality product that does exactly what it says it will. Very satisfied!

These are excellent for jobs that you decide you want to add an attachment after the profiles are assembled. They are a little fiddly to place and hold while screwing bolt in but work great at a small fraction of the cost of purchased from 80/20.

These sliding t-nuts work perfect. The previous reviewer who gave this a bad review does not understand how these type of fastener are supposed to work. Since they are drop in, they will naturally need to be narrow.

I use 10 series from TNUTZ and these so called roll ins neither roll in, or are tight. They are a fit where they touch deal. Sloppy and do not fit the slot properly. I will not buy again. Total rubbish.
