More info
This item is a Hook Bolt Expansion Anchor (commonly referred to as a Wall Plug with Hook). It is a high-strength mechanical fastener designed for creating secure, semi-permanent hanging points in solid base materials such as concrete, solid brick, or stone.
Product Specifications & Features
-
Material: Heavy-duty Carbon Steel with a Yellow Zinc Plated finish. This coating offers reliable protection against rust and oxidation, making it suitable for damp or outdoor environments.
-
Expansion Design: The assembly includes a threaded hook, a hex nut, a flat washer, and a heavy-gauge expansion sleeve. As the nut is tightened, the internal wedge pulls into the sleeve, causing it to expand and "lock" into the substrate.
-
Open Hook Head: Features a sturdy open-style hook, allowing for the easy attachment and removal of items like chains, cables, or eyes without needing to dismantle the hardware.
-
Industrial Strength: Provides significantly higher load-bearing capacity than plastic anchors, specifically designed to withstand constant tension.

Technical Installation Guide
-
Drill: Use a masonry bit that matches the outer diameter of the expansion sleeve.
-
Clear: Blow out any dust from the hole to ensure the sleeve can grip the surface effectively.
-
Insert: Tap the anchor into the hole until the washer and nut are flush against the wall or ceiling.
-
Secure: Use a wrench to tighten the nut. Note: Do not over-tighten, as this can stress the base material; tighten just until the anchor feels completely immobile.
Important Selection Notes
-
Base Compatibility: Only for use in solid materials. Do not use in hollow blocks, drywall, or mortar joints, as the expansion force could cause the material to crack or the anchor to pull out.
-
Orientation: When installing in a ceiling, ensure the load does not exceed the "pull-out" rating for that specific bolt size (typically available in M6 to M12).
-
Removability: While the hook can be unscrewed, the expansion sleeve is designed to remain permanently in the wall once expanded.
Commonly used for: Heavy-duty hanging requirements where a standard screw-in hook is insufficient.
