Would RecommendNeeded a screw to pull the side of a door casing back in place. Used these screws and they worked great. They pulled the casing up tight against the door framing. Holding tight. Good screw type for solid mounting.

Need a special bit (included) T20
these work great for decking and framing, also good for anchoring heavier items. I use these around our cabin.
