💡 How does drive geometry and thread pitch impact load ratings on exterior fasteners?
To get the job done right, you need proper alignment and steady speed when tightening. - Deep star recesses channel rotational force directly into the substrate - Coarse thread spacing grabs softwood fibers faster to reduce spin out - Electrolytic plating layers create thicker barriers against salt air exposure
