<p>STURDY: Using drywall anchors on a regular basis, you always worry that they will pull out or fail because they are not strong. Our anchors are made of durable reinforced nylon construction with 50 lbs. of holding strength, making them extremely strong.CARBON STEEL SCREWS: Our drywall anchors come with screws made of carbon steel, which are more resistant to rust than regular screws, so you won't have to worry about your wall anchor's screws getting rusty and weak.ANCHOR BOLTS MADE FROM FIBERGLASS REINFORCED NILON: While most gypsum board anchor bolts are made from regular plastic, our anchor bolts use tough fiberglass reinforced nylon. With our drywall screw kits, the cracked design allows you to install fasteners without the frustration of breaking or falling off.EASY TO USE: Our wall screw fasteners are very easy to use. They are self-tapping screws that do not require pre-drilling or pilot holes. Because only one drill bit is needed, you can install as many as you want on sheetrock and drywall. They are great for hanging bathroom and kitchen accessories, shelves, light fixtures, mirrors, picture frames, curtain rods, and small decorative shelves, but be aware that they are not suitable for concrete and brick walls.NEW DESIGN: DEEP THREAD DESIGN: Self-drilling drywall anchors with a deep thread design are safe to use on drywall!</p>
