T-Nut For 3030 Extrusion | T-Slot-Nut All Plastic

This T-nut for 3030 extrusions doesn't require a hex nut or brass insert, as the bolt is screwed directly into the plastic.
T-nuts for classic hex nuts often have the problem that they are weakened by the thinner plastic or one often pushes the nut out the back when screwing in.

For simple applications, the plastic thread is totally fine.
