Purchased to build my AM8 3d printer. Worked great however I needed to buy additional nuts and bolts, not sure if that is my fault, if I was using more than needed.

These are pretty good for the price. They're not the strongest materials or the highest quality bolts, but the sellers do seem to have corrected the length problem that other buyers reported earlier. I haven't found anything comparable for the price.

Just what I needed

Helped me get my CNC put together. Perfect for putting 80/20 tracks together

All correctly shaped, which I can't say about all profile connectors I've bought. Only problem was I didn't realize that I was lacking an m5 key, however that's my fault. Wish this had a m5 key provided...

Very sturdy corner connections

These are the fittings and screw-downs for the 80/20 Inc. 20-2020 series T-slotted extrusion, so if you buy one, be sure you buy the other.

Excellent buy, saved me money and the quality is great! Recommended!

came fast and packaged well. THEY WORK GREAT! VERY HAPPY, THANKS!
