Hollow Wall Drywall Anchor Expansion Bolt Set — 6mm / 8mm Carbon Steel | 10–100 Sets

Reliable fixings for hollow walls, plasterboard, gypsum board, and tile where standard wall plugs fail. These carbon steel expansion bolt sets are engineered for cavity wall applications — the expansion tube collapses and grips the back face of the board as the screw is tightened, distributing the load across a wide area and providing a secure anchor even where there is no solid backing. Each set includes one self-tapping screw and one expansion tube, available in 6mm and 8mm sizes with 10 to 100-set packs for single-job through to trade supply.

How Hollow Wall Anchors Work

  1. Drill: drill a hole in the hollow wall or tile to match the expansion tube diameter (6mm or 8mm).
  2. Insert tube: push the expansion tube fully into the hole until the flange sits flush with the wall surface.
  3. Insert screw: pass the screw through your fixture (shelf bracket, hook, cable clip, etc.) and into the expansion tube.
  4. Tighten: as the screw is tightened, it draws the expansion tube inward, causing it to collapse and spread behind the wall face — creating a mechanical lock that cannot pull through.

Size Selection Guide

Size Drill Bit Max Load (approx.) Best For

Frequently Asked Questions

Q: Will these work in ceramic tile over hollow walls?
A: Yes, with a tile drill bit. Drill through the tile first with a carbide or diamond tile bit, then switch to a standard bit for the plasterboard behind. Insert the expansion tube and proceed as normal.

Q: What is the maximum wall thickness these work in?
A: The 3cm expansion tube accommodates standard 12.5mm and 15mm plasterboard. For thicker boards or double-layer plasterboard, verify the tube length against your wall thickness before ordering.

Q: Can I reuse these anchors?
A: No. Once expanded, the tube is permanently deformed. If you need to remove a fixing, the anchor must be replaced with a new set.
