I decided to buy these for heavier items that I needed to hang on the wall. It would be overkill for using this to hang family photos on the wall so make sure you know what you are getting but great wall anchors nonetheless, very durable and very well made. I also recommend that users only use installation tools (guns). ) to secure those molly tools (wall anchors). It's much easier, faster and easy to make a mistake - never try to screw these screws into a wall, it will often fail. I've included two pictures showing the two types of installation tools I use with these screws. . I prefer the "Red" but the "Blue" has more of a ratchet mechanism which should be easier for those with little strength to grab the red tuning tool with their hands (Hulk Power!) with a full squeeze. I love the different sizes that come with this set. They make most tasks and wall thickness easier considering these molybdenum screws are for heavier items.
