Review on WoodPro Fasteners ST516X318B Exterior 250 Pack by Edgardo Ennis

These external screws are excellent value for money, spin smoothly and the washer helps to hold items. I install DaVinci Roofscapes products and use them on pitched, ridge and hip shingles. I like the outer shell. I would compare them to GRK RSS screws. The main difference is that GRK can cut cement board better and WoodPro has a better surface. You can't go wrong with these screws.
