Foundation bolts, also known as anchor bolts, are strategically placed during the initial stages of construction to securely connect structural elements to their respective foundations. They act as the bridge between the concrete foundation and the superstructure, transferring loads from the structure to the ground. Their design varies, from J-bolts to U-bolts, each tailored to suit specific engineering requirements and soil conditions.

Structural bolts are made from high-strength materials such as grade 5 or grade 8 steel, making them resistant to corrosion and wear. They are heat-treated to achieve the necessary tensile strength, which can range from 120,000 to 180,000 pounds per square inch (psi). This high-strength capacity is crucial for withstanding the dynamic forces and stresses that structures face over time, including wind, seismic activity, and the weight of the structure itself.

Expansion anchors are designed to expand when the resin cures, providing a strong hold in soft or friable substrates such as concrete or masonry. Plug anchors, on the other hand, rely on friction to hold the blockwork in place and are suitable for harder substrates such as brick or stone. Screw anchors are similar to plug anchors but have a threaded shank that allows them to be tightened to provide a more secure hold Screw anchors are similar to plug anchors but have a threaded shank that allows them to be tightened to provide a more secure hold Screw anchors are similar to plug anchors but have a threaded shank that allows them to be tightened to provide a more secure hold Screw anchors are similar to plug anchors but have a threaded shank that allows them to be tightened to provide a more secure holdresin anchors for blockwork.
