How to Install Screw Anchors
Light products are often sold with the screws and plastic sleeves already in the pack. Medium-heavy objects, such as mirrors and or shelving, should be hung using toggle bolts.
If the object being hung is especially fragile or valuable, consider purchasing heavy-duty wall screws, such as Toggler SnapSkrus. These self-piloting sleeves come with their own screws and hold up to 65 pounds each in drywall.
While fairly expensive, SnapSkrus provide a more stable anchor than the push-in plastic sleeve anchors that are provided for free with some products.
But if the item is fairly light and isn't especially valuable, the plastic sleeve anchor screws work fine because they still have a good degree of shear strength.
