FAQ on screws and anchors
What are hardware fasteners used for?
Hardware fasteners include all the components used to join, secure, or support materials — such as anchors, screws, bolts, and nuts. They’re essential for construction, renovation, and DIY projects of all sizes.
What are the most common types of mounting hardware?
Mounting hardware includes wall anchors, brackets, hooks, and screws. These items are used to install shelves, mirrors, cabinets, or any object that needs secure support on a wall or structure.
How do I choose the right anchor and screw combination?
Choose your anchor and screw based on the weight and surface type. For drywall, use plastic or toggle anchors; for concrete, use masonry anchors; and for wood, a standard wood screw may be enough without an anchor.
