60pcs 3P 5.08mm Pitch 3Pin PCB Mount Screw Terminal Block Socket Strips for Arduino, Blue

I have read reviews from other products and strength of terminal body and a desire for Phillips capability seemed to be priorities. In a past life I used to build industrial control panels, and terminals had to be tightened to 7in/lbs . I found terminals on various devices could and sometimes would deform when tightened. I have found these terminals to be very strong and show no signs of deformation when a torque of approx 7 in /lbs. I usually use a well fitting flat head screwdriver . Screw assemblies seem to be captured and found no screws falling out from backing them out beyond what appears to be max travel open. A little effort was needed to open up clamp if tightened then loosened but not significant or difficult any more than putting in a small screwdriver to open up . Prongs are large enough to work on a solderless breadboard. I think that covers everything.

I used these on a standard 0.1" pitch perf board. Each terminal block takes up 5 holes and another block can be abutted if more terminals are needed. The pins fit snugly so they wont fall out easily.

I really like these connectors; they fit perfectly according to the mechanical drawing provided, and they very securely grasp the connecting wire when the screw is tightened.The price is good, the performance exactly what is needed.Highly recommended.

I have been using these from Samldea for some time now. Reason good product and best price.All have been well made and work as expected.

They're built a little cheaper than others, but they work well none the less.
