💡 What determines load capacity when bolting heavy duty corner brackets to dense lumber?
Shear strength depends directly on steel gauge thickness and screw thread pitch depth. Standard fourteen gauge iron spreads bending stress away from glued seam weak points faster than cheaper stamped alloys ever could. Clean deburred hole edges reduce cross grain tear out while driving mounting hardware tightly.
