Galvanized Steel Self-Drilling Expansion Bolts: Durable and extremely strong. Self-drilling drywall expansion bolt and screw sets simplify the installation process, allowing items to be directly fixed to drywall without pre-drilling. Material: The screws are made of galvanized carbon steel, ensuring a robust and durable structure. Compared to traditional plastic expansion bolts, no drilling is required in the wall, avoiding damage to the wall surface and leaving no holes after use. Removing the expansion bolts is as simple as pulling them out of the wall by 1-2 mm without causing any damage. Easy Installation: 1. Tap the expansion bolt into the drywall; 2. Pass the screw through the fastening mechanism and screw it into the metal expansion bolt; 3. Tighten the screw. More convenient and faster than traditional plastic expansion bolts. Wide Range of Applications: The deep thread design can connect various materials such as concrete, drywall, insulation board, and hollow bricks. Suitable for hanging or fixing paintings, garden decorations, garden sculptures, wall lamps, curtains, televisions, blackboards, cabinets, pergolas, awnings, etc. Heavy-duty drywall anchors: Featuring an expandable design, these anchors have ribbed protrusions and tapered tips. When tightened, the sides expand, enhancing the grip. These drywall anchors are ideal for securing umbrellas, garden furniture, swing stands, and garden scarecrows.
