Review on πŸ”© Pack of 50 M3 x 4mm (L) x 5.0mm (OD) Female Thread Brass Embedment Nuts with Knurled Threaded Insert by uxcell by Joshua Paulson

Revainrating 5 out of 5

20% scrap on nut inserts

Good if you only need 40 out of 50. Some of them have mismatched internal thread diameters. The knurling varies for each insert. some are missing completely. The main problem is their concentricity. Not recommended for 3D printing. They are designed for injection molding. The pull force is about a third of the inserts designed for actual 3D printing.
