Review on 🔩 cSeao 120pcs M3 x 3 x 5mm Female Thread Brass Heat Set Inserts Embedment Nuts for 3D Printer, Laptop, and Plastic - Enhanced SEO by Wesley Carreras

i need about eight so my project is good. I bought 80 and less than half of the bag met the specs. In fact, the pitch is not indicated on the bag, only M4. The pitch is said to be 0.7mm and this applies to about 30 of them, with the rest not bolted to M4x.7 screws. Included is a picture of some of the buzzers I received in the bag that did not meet the specs. Note jagged edges and some broken ones. Some expensive spare parts package. I hope to keep the right ones.
