Review on SML C250B 50 Blue Kote Pocket Washer Head - High-Quality 50 Count for Superior Performance by Adolfo Goins

These screws are of acceptable quality but not up to the task. I wanted them to assemble a 2x4 PT handrail on a small stair case (4 steps). They are too thin and too easy to remove. I'm showing a picture to compare with the DeckMate screws I usually use. I wanted to use pocket holes for easier assembly. But in the end I had to go back to a more powerful propeller which I'm sure will stand the test of time.
