What Is Holding Down Bolt?

A holding down bolt, also known as anchor bolt or foundation bolt, is a large, heavy-duty fastener used to anchor a structure, such as a steel frame or machinery, to its concrete foundation. It is installed before the concrete is poured and provides a secure connection that resists forces like wind and seismic activity, ensuring the structure's stability and integrity.  

There are many types of holding down bolts, consisting of designs that are mostly proprietary to the manufacturing companies. All consist of a threaded end, to which a nut and washer can be attached for the external load.

Where Are Holding Down Bolts Used?

Holding down bolts are used to securely anchor structural elements and heavy machinery to concrete foundations. They are essential for structures like steel columns, equipment bases, generators, and tanks, and are also used for infrastructure such as streetlights and traffic signals. 

Common applications

  • Structural steel: Securing structural steel columns and other elements to concrete bases in buildings and pre-engineered structures.

  • Machinery and equipment: Anchoring heavy machinery that produces vibrations, such as generators, pumps, and compressors, to prevent movement.

  • Infrastructure: Fastening outdoor elements like streetlights, traffic signals, and signboards to their foundations.

  • Industrial tanks: Securing large tanks and other industrial vessels to the ground.

  • Crane systems: Fastening and anchoring components in rail systems, including overhead and gantry cranes. 

different types of Holding Down Bolts

Square Plate Washer for Holding Down Bolt

Square plate washers are used in a variety of applications but are most commonly used with a holding down bolt, straight rod, anchor bolt or sometimes loose. The use of plate washers with holding down bolts can provide a larger surface area to the base of the fixing. This means it would require substantially more force to pull the holding down bolt out of its embedment.
