What is a foundation bolt?
A foundation bolt is an anchor embedded in a concrete foundation so that a structure, base plate or piece of equipment can be fixed to it. One end is cast into or grouted within the concrete; the other end projects above the finished level and is threaded to receive a washer and nut.
The embedded end is shaped — bent, hooked or fitted with a plate — so that load applied to the projecting end is transferred into the concrete rather than pulling the bolt out.
Where are foundation bolts used?
Foundation bolts appear wherever a steel structure or machine meets concrete.
- Structural steel column base plates in industrial buildings
- Solar module mounting structures and tracker foundations
- Transmission towers, gantries and substation equipment
- Pre-engineered buildings, warehouses and sheds
- Machinery, pumps, compressors and process equipment
What information is needed to order them?
A drawing or sketch is the fastest route to an accurate quotation. Where a drawing is unavailable, share the diameter, total length, bend or plate detail, thread length, projection above concrete, material or grade preference, surface finish, quantity and delivery location.
