Our galvanized metal assorted‑head hollow wall anchor (anti‑slip hollow wall anchor) is made of high‑strength carbon steel (Grade 4.8/8.8) with a bright blue‑white zinc / eco‑friendly galvanized finish for corrosion resistance. The flange with anti‑rotation spikes increases friction to prevent spinning during installation; the extended expansion sleeve with long slots ensures full expansion in hollow bricks and drywall for superior grip. The assorted head/hook compatibility – the same anchor accepts cross recess, external hex, internal hex, or hook attachments – offers flexibility for various installation needs. Sizes M4‑M10, lengths 60‑150mm custom. Ideal for indoor drywall heavy loads, hollow brick reinforcement, ceiling suspension, and pipe/panel mounting. Installation: drill → insert anchor → tighten with the appropriate tool – the built‑in pull‑tight locking mechanism expands automatically in one step.

Flange Anti-Slip Spikes – No Spinning During Installation
The flange bottom features dense anti-slip spikes that bite into drywall or surface layers during tightening, effectively preventing the anchor from spinning freely with the screw. Even under resistance or vibration, the spikes firmly grip the substrate, ensuring all torque converts into locking force rather than wasted on slipping – significantly improving installation success rates and efficiency, ideal for solo overhead work.
01
Extended Expansion Sleeve + Long Slots – Stronger Grip in Hollow Substrates
The extended expansion sleeve with long slots expands fully in hollow bricks, drywall, or aerated blocks, offering far greater contact area than ordinary short anchors – significantly increased holding power. Long slots ensure uniform expansion, avoiding localized stress concentration that could crack the substrate. The built-in pull-and-lock mechanism automatically triggers expansion during tightening – no extra steps, reliable anchoring that stays secure even under heavy loads or long-term vibration.

Assorted Heads/Hooks – One Anchor, Multiple Uses
One anchor compatible with multiple head types – Phillips, external hex, internal hex, and hook styles – matching different tools and installation preferences. No need to stock multiple models for various scenarios – simpler inventory management. Hook styles are perfect for hanging pictures, lamps, and tool racks without extra accessories. Whether for wall fixing or hanging, just one anchor handles all – greatly reducing part costs and selection time.
