Questions about this product
- What walls are these anchors meant for?
- They're built for hollow materials where normal anchors pull out, like drywall, ceramic tile, and hollow-core walls. The expansion pipe spreads pressure behind the surface for a firm, flush hold. Good for shelves, mirrors, grilles, and light fixtures.
- How do I install these anchors?
- You drill a hole sized to the anchor's outer diameter, push the expansion pipe in, then drive the self-tapping screw. The screw cuts its own thread and expands the pipe for a tight grip. A drill is required, so this isn't a tap-in anchor.
- What size screws and anchors are in the kit?
- Anchor pipes run roughly 8 to 12mm across and 40 to 60mm long, with screws around 4 to 5mm by 35 to 55mm. You can buy it in 10-set or 500-set packs. The bulk option suits big jobs or keeping spares on hand.
