It's just a screw. Nothing magical.
Would RecommendVery good structural screw. I used these to secure attic door frame to the house joists. The shear rating for these screw was highly recommended by Gemini AI, so I went with it. They are pricier than other brands, so you can choose based on your application, and risk vs cost.

Great wood screws
Would RecommendNeeded quality screws for a project I was doing. Love the fact that these don’t strip out when installing them like other cheap wood screws. Worked as they were intended.

GRK Only
Would RecommendGRK is the only screw brand I used these days for any projects, indoor or outdoor depending on which one you buy. Easy to install, but also easy to remove with vs a Phillips which can strip the screw head. These screws hold up nicely, used them for the construction of framing for a shed for extra support, and on the T11 to 2x4 connection for a strong hold.

Would RecommendT25 screws are the way to go when working on anything structural, and GRK has never let me down, these screws are no exception. Stronger than nails and stand up to the elements.
