Cast-In Ferrules & Threaded Concrete Inserts
Cast-in ferrules are threaded concrete inserts designed to be installed into precast concrete before pouring, creating a permanent anchor point once the concrete has cured. Commonly used in precast and structural concrete applications, cast-in ferrules allow bolts or threaded rods to be installed after placement, simplifying construction and improving fixing accuracy.
These concrete ferrules are widely used in precast panels, beams, columns and other reinforced concrete elements where reliable post-installed fixings are required. Many designs incorporate anchorage features such as enlarged or square bases and reo bar cross holes to improve load transfer and resistance to pull-out forces.
Our range of cast-in ferrules includes solutions suitable for general construction as well as corrosive or marine environments, with options available in galvanised steel and stainless steel.

FAQs
Q1. What is a cast-in ferrule?
A cast-in ferrule is a threaded insert installed into precast concrete formwork before the concrete is poured, creating a permanent anchor point for bolts or temporary attachment of braces and strongbacks.
Q2. What are cast-in ferrules commonly used for?
Cast-in ferrules are commonly used in precast panels, beams, columns, and structural concrete elements where fixings are required after installation.
Q3. What is the difference between a cast-in ferrule and a threaded insert?
A cast-in ferrule is a type of threaded insert specifically designed to be embedded into concrete prior to pouring, often incorporating anchorage features such as feet or reo bar holes.
Q4. Why do some cast-in ferrules have a square or enlarged base?
An enlarged or square base increases anchorage within the concrete, helping resist pull-out forces and improving load performance.
Q5. What materials are cast-in ferrules available in?
Cast-in ferrules are commonly available in galvanised steel and stainless steel, depending on environmental exposure and corrosion requirements.
