The Sleeve Anchor with C-Hook (also known as a “Hook Bolt Expansion Anchor” or “Masonry Hook”) is a heavy-duty fastener designed for suspending loads from solid concrete, brick, and stone walls. Unlike light-duty plastic plugs, the Sleeve Anchor with C-Hook features a full-length steel expansion sleeve that distributes the load evenly within the drilled hole, providing a secure, vibration-resistant hold for clotheslines, hanging baskets, and security chains.
Product Overview: Manufactured from Carbon Steel with a durable Yellow Zinc Plated finish, this anchor resists corrosion in outdoor environments. The unique design features a threaded hook bolt encased in a cylindrical sleeve. A hex nut and washer at the base of the hook allow for torque-controlled expansion without rotating the hook itself.

Engineering Insight: Why use a Sleeve Anchor Hook?
The Sleeve Anchor with C-Hook offers distinct advantages over standard shield anchors:
- Directional Control: Standard screw-hooks must be turned to tighten, meaning the hook might end up facing the wrong way when tight. Our design uses a separate Hex Nut for tightening. You can hold the C-Hook in the perfect position (e.g., opening facing up) while tightening the nut with a wrench to lock it in place.
- Full Expansion: The sleeve expands along its entire length, maximizing contact with the hole. This is crucial for “soft” masonry like red brick, where point-loading anchors might crack the material.
For more details on expansion anchor mechanisms, please refer to the Anchor bolt entry on Wikipedia.
Installation Guide
- Drill: Drill a hole of the same diameter as the anchor sleeve (e.g., 10mm bit for an M8 anchor).
- Insert: Clean the hole and insert the anchor until the washer and nut are flush with the wall.
- Align: Position the C-Hook opening in your desired direction.
- Tighten: Turn the hex nut clockwise with a wrench. This pulls the tapered cone at the bottom of the bolt into the sleeve, forcing it to expand and grip the wall.
Frequently Asked Questions (FAQ)
Q: Can I use this on a ceiling?
A: Yes, provided the base material is solid concrete. However, for overhead lifting safety, verify the load capacity and ensure the C-Hook opening won’t allow the item to slip out. For critical overhead loads, use the Eye (Closed Loop) version.
Q: Is it rust-proof?
A: Yellow Zinc plating offers good resistance for normal outdoor use. For marine or coastal environments, we recommend our Stainless Steel Sleeve Anchors.
