Work fine for minor structural or framing repairs.
Would RecommendFairly stout although not the shear strength of a nail. However they are better than deck screws for framing and construction--those would be silly to use for framing or structural purposes. I thought they would be a bit stouter. They feel in between the bendability and strength of a nail and a deck screw.
