ZYAMY 50pcs KF301-2P/3P PCB Panel Mount Screw Terminal Block Connector(30pcs 2-Pin+20pcs 3-Pin)

Great Quality - Works as needed.

No issues - they PERFECTLY FIT the 0.1" pitch Project Boards I have (with tinned, copper pads on BOTH SIDES). The fit is "just" snug enough in the board holes to hold the terminals while you solder ONE PIN to "lock it down" before soldering the rest of the pins.The screws are on the "small" size, requiring a "0" size Phillips to properly tighten/loosen them.The terminal holes themselves aren't "high quality", but if you ensure the wire end is in a FERRULE (up to #16 size, I think?) or TINNED or CRIMPED/SOLDERED to a connector pin, tightening the screw makes a Very Secure Connection.A BIG PLUS: the terminals can be "joined" to make LONGER terminal "chains". Just make sure your board is Long Enough to handle the chain. :)Finally, the PIN SPACING between terminals is ** 0.200" ** (i.e., TWO (2) HOLES), so ensure you factor that "real estate" need when you design your board layouts.For the "average" DIY-er, these are great. I WOULD NOT recommend them for "Mission-Critical" or similar "production" uses - $pend the $$$ on Higher-Quality terminals designed for "Mission-Critical, etc." needs.Otherwise, I ** DO RECOMMEND ** these terminals, with the noted "caveats, etc." above... :)

Good item

These are good parts, except that its pins do not fit in the holes in the prototype board I have. They do fit well in a breadboard, but they are of little use unless I can enlarge the holes in my board. The spacing of the pins takes two "columns" on a board, but the terminals are large enough to be useful.

Liked that they fit snugly onto a solderless breadboard. Like that they align next to each other without jamming.Don’t like that the pins are spaced every two slots in the board so takes up unused space.
