Anchors

When put into materials, anchors offer a secure hold. Anchor screws, which feature sharp threads and a robust material construction, are threaded anchors that are used to bore into concrete or drywall and provide a firm hold. Drive-pin anchors, which expand in predrilled holes when hammered in, and drop-in anchors, which are internally threaded and designed to expand when accepting corresponding bolts, are examples of expanding anchors.
