Drywall anchors kits can support objects with the maximum weight of 66 pounds, and can be used to connect gypsum wallboard with the size of 3/8 inch, 1/2 inch or 5/8 inch drywall, which is very suitable for hanging various items on the walls at home, such as photo frames, wall lamps, curtains, clocks, plants, televisions and cabinets. Drywall anchors are made of Upgraded Zinc Plated Steel, and the surface of the product is plated with yellow zinc which is not easy to oxidize, which is firm, wear-resistant and aging-resistant. The screws are made of heavy-duty steel, which is more sturdy and rust-proof. Through-wall screw fasteners are easy to use, do not need pre-drilling and will not damage the wall. First, knock the expansion nail into the wall, then screw the fixed objects together, and finally tighten the screws. When you tighten the screws, the cracks of the ribbed anchor nail expand on the opposite sides, which increases the fixing force. The deep thread design can firmly fix the items on the wallboard, which provides a firm fixation and pull-out resistance for the wall anchor and screw kit. Reusable, easily remove screws and objects, leave the anchor on the wall for reuse, and leave no holes in the wall.
