This product is a comprehensive wall - mounting solution featuring 80 steel anchors (measuring 0.47 x 1.18 in. or 12 x 30millimeters) and 80 screws. Installation is a breeze - simply knock the anchor bolts into the drywall, thread the screw through the fixture and insert it into the metal plug, then tighten the screw, offering a more convenient and rapid process compared to traditional plastic anchors.

The conical tip of the wall screw anchor bolts ensures easy installation with minimal wall surface damage, and the ability to remove the screw and item effortlessly, leaving the anchor in the wall for reuse without any residual holes, thanks to the thorough screw - in design for more logical and straightforward expansion. Moreover, they are compatible with gypsum wallboards of 3/8 in. 1/2 in. or 5/8 in. drywall dimensions, making them ideal for hanging a wide range of items at home, including picture frames, wall sconces, curtains, clocks, plants, and cabinets.
