Review on 🛠️ Enhance Your T-Slot/V-Slot Aluminum Extrusions with Hammer Drop-in M5 T Nut (Pack of 25) by Paul Opoku

At $0.36 each this is amazing. Almost identical to the OpenBuilds nuts, I've used them for V-slot extrusion with no problems. They are strong and easy to deploy, with lots of threads. You will need 8mm screws for most of the items attached to it. If you're using OpenBuild's V-Slot and need cage nuts, get them here - don't buy them from OpenBuilds for their asking price ($0.75 each). at the time of this writing). I love OpenBuilds, but you can save money by using alternative sources.
