Qrity 20 PCS Threaded Sleeves, Threaded Repair Insert Nut, M6 x 6mm Male to M3 x 6mm Thread Female Thread Inserts, Thread Reducing Nuts

Very good quality product works great and is highly recommend

The media could not be loaded. I ordered these in the wrong size and cannot use them as is. i will probably end up drilling and tapping for another size instead of replacing them. That said they look fine for non-critical applications, which is why I ordered these.These do not have driver slots, so you can use a screw jam nutted on the insert side and to the screw head side and drive with a wrench; I will sacrifice one and slot cutter grooves with a Dremel so that I can use one as a tap in wood or soft materials.
