🔩 Premium 250-Pack WoodPro Fasteners ST516X518B Exterior Review

Great heavy duty screw at a good price. Went to every major hardware and specialty hardware store and couldn't find a better screw at a great price.

This is my favorite fastener for high strength wood fasteners. Low installation torque, high holding power due to large thread and wide top flange. Five stars.

These screws have some great features. First they are marked at the point where they are just beginning to penetrate a four inch (3 1/2 inch) piece of wood. I use them to butt a 2x4 over a thicker board size to another piece of wood and they're great for that. Like all screws, they try to "walk" along the grain, so you need to make sure they're screwed in the right direction/angle or you could end up with a point protruding from your wood. They are long enough that even a slightly wrong angle…
