Are You Hanging Heavy Items Safely?
Whether you are installing a new ceiling fan in your living room or setting up a sturdy clothesline in your backyard, the safety of your installation depends on one thing: the anchor.

In the Kenyan construction and DIY landscape, the Open Hook Eye Bolt Anchor is the “gold standard” for securing medium-to-heavy loads to solid surfaces like concrete or brick. At Technology and Materials, we provide professional-grade fastening solutions that ensure your fixtures stay exactly where you put them.
What is an Open Hook Eye Bolt Anchor? (The Quick Answer)
An open hook eye bolt anchor is a heavy-duty expansion fastener designed for solid materials like concrete or stone. It features a threaded bolt with an open-ended hook and an internal expansion shield. When tightened, the shield expands against the sides of the hole, creating a permanent, high-strength hold for hanging items like fans, lights, or acoustic ceilings.
How Does It Work?
The genius of this hardware lies in its simple yet powerful design:
4 Common Use Cases in Kenyan Homes
Here is how our clients in Nairobi and across Kenya are using these anchors:

In many Kenyan homes, ceiling slabs are solid concrete. Standard screws won’t hold the weight of a heavy orbital fan or a modern chandelier. An eye bolt anchor provides the mechanical strength needed to ensure your fan doesn’t vibrate loose over time.
For commercial spaces or modern homes using acoustic ceiling tiles, these bolts act as the primary hanging points for the galvanized wire systems that support the ceiling grid.
Want to hang a heavy potted plant or a hammock on your balcony? Because these anchors are designed for “medium loads,” they are perfect for creating relaxation spots that can support the weight of an adult or a large, water-saturated flower pot.
Tired of flimsy clothesline hooks pulling out of the wall? Using an M6 or M8 expansion bolt creates a permanent anchor point for high-tension clotheslines that won’t budge, even with a heavy load of wet laundry.
