Currently, one of the challenges with sourcing M heads is that it can be difficult to find high-quality ones on Taobao. This is especially true for premium M heads... unless you go to Digikey or Mouser and buy AMP or TE heads for several hundred yuan each. However, Taobao offers a large selection of inexpensive N heads with specifications and certifications.
The images above show some recent purchases, but I wasn't entirely satisfied with them. The two heads on the far left are particularly problematic; the manufacturer has made the connection wall extremely thin in order to save on copper (one is a 50-1.5 head, and the other is a 50-5 head).
Furthermore, both of the connectors had the same problem: the screw holes were very deep. If used on a device with a short pitch (e.g., video), feeding the cable directly into them would be difficult because I frequently assemble and disassemble them... And soldering is also quite complicated, so I currently prefer to use crimp connectors.

The two bottommost pieces are welded and pressed together, and both heads are very light. The connection between the welding head is a peculiar white color, and I'm not sure what material it is made of.
The sleeves provided with the compression fittings are very large; after compressing, you can easily pull them out.
