What is a Foundation Bolt?
A foundation bolt is a structural bolt used in construction. It comprises three parts: the foundation bolt, a square washer plate and a waxed cardboard cone.
Also known as
Square square holding down bolts, construction bolts, or anchor bolts.
Why use Foundation Bolts or Holding Down Bolts?
Foundation bolts are essential for building solid foundations, particularly in steel fabrication and industrial or agricultural building projects.
Unlike drilling, which can put stress on the concrete, foundation bolts are cast into the concrete at the foundation stage, so everything is secure before construction begins.
This way, when your contractors arrive on site, they can immediately start work with the foundations already set.
Foundation Bolts: How they work
First, you excavate the site, mark out the footing, position the bolts and pour the concrete around them. You then bolt down steel uprights with usually four foundation bolts, creating a template that matches the baseplate.
