100PCS 2 Pin 3 Pin 4 Pin PCB Mount Screw Terminal Block Connector, KWOKWEI Blue Socket Strips 5mm Pitch for Arduino and Home Electronics Projects (80 x 2 Pin, 15 x 3 Pin, 5 x 4 Pin)

These little things are a must-have for many of my electronic projects. The quality was good and they work as expected. I would definitely buy more of them.

The media could not be loaded. They are great quality and seem stronger than my normal green ones, but they are much larger and take up a lot of holes for just a 4-pin block.Will buy more though because these can fit more wires if needed

It was bought as a gift and they liked it

When I am prototyping circuit boards or building breakout boards for testing single board computers I need an easy and convenient way to switch wires or supply power to the boards instead of permanently soldering wires to the prototype boards. The KWOKWEI kit comes with lots of 2pin, 3 pin and 4 pin screw terminal block connectors which I solder to the circuit board. They are useful for the final PCB to allow for easy connect/disconnect of the power supply or signal leads.

some of these blocks were unuseable due to the screws being molded right into the block you could not even turn them.

These are awful. The metal seems too be way too soft. The pressure pad that moves up and down is not smooth. The screw will lock up and then the it strips way too easily. Of the first five I pulled from the box, at least one of the terminal screws did not work. I tossed the whole box in the trash. Where they belong.

Yep. You guessed it.These are the ubiquitous, old-fashioned terminal blocks for through-hole mounting on circuit boards.A good assortment in good quantities.

I needed two and for the price it is much more economical to purchase this pack then go to Home Depot. Easy to install. Happy to have extras for later use.
