PREMIUM NYLON MATERIALS PLUS GLASS FIBER - Made of high-quality hard nylon plastic mixed with highly robust glass fibers, these threaded self-tapping wall anchors are super hard, durable, anti-aging and wear resistant. They can hold objects with maximum weight of 50lbs and provide strong and sturdy grip into the wall. 50 premium galvanized Phillips screws ensures reliable installation and mounting. | PRACTICAL DESIGN FOR STABLE INSTALLATION - The threads cut deep into the material, providing a secure hold and pull-out resistant grip of the wall anchor and screw kit. The large threads are intended to hold firmly in drywall and can hold up to 50 pounds of objects. | EASY INSTALLATION WITH SCREWDRIVER - These threaded drywall anchors feature sharp, pointed shanks that can be screwed into the wall without a pre-drilled hole by using a screwdriver or a screw gun, which produces less dust. Once the anchor is in the wall, the screw is inserted, the anchor will wedge tightly against the drywall. | HEAVY DUTY & WIDE APPLICATION - The self-drilling drywall anchors are recommended for medium-duty applications and are very easy to install.
