Anchor Bolts
Anchor bolts are specialized fasteners used to attach objects or structures to concrete or masonry surfaces. They provide a secure and stable connection, ensuring that the attached item remains in place, even under significant loads or forces.
-
Design: Anchor bolts typically consist of a threaded end and a non-threaded (Single End) end, two threaded ends (Double End), or Headed. On Single end threaded anchors the threaded end is embedded into the concrete or masonry substrate. The non-threaded end may have a variety of shapes, such as a hook, a square bend, or a flat plate, depending on the specific application requirements. Double End anchor bolts with thread on both ends are typically used for anchoring machinary and equipment. Headed Anchor Bolts can be manufactured with the head or often times a tack welded nut is an acceptably option for the head.
-
Materials: Anchor bolts are commonly made from materials such as carbon steel, stainless steel, or galvanized steel, depending on factors such as corrosion resistance, strength, and environmental conditions. Stainless steel and galvanized steel are often preferred for outdoor or corrosive environments due to their resistance to rust and corrosion.
-
Applications: Anchor bolts are used in a wide range of applications across various industries, including construction, infrastructure, and manufacturing. Common uses include securing structural steel columns, attaching equipment and machinery to concrete floors, anchoring outdoor structures such as fences and signs, and installing handrails and guardrails.
-
Load Capacity: The load capacity of anchor bolts depends on factors such as the type of anchor, the diameter and length of the bolt, the depth and quality of the concrete or masonry substrate, and the installation method. Engineers typically specify anchor bolts based on the anticipated loads and structural requirements of the application. Standard grades include ASTM F1554 GR 36, GR 55 and GR 105. ASTM A36 / GR 2 Anchor bolts are also common.
In summary, anchor bolts are essential fasteners used to secure objects or structures to concrete or masonry surfaces. With a variety of types, materials, and installation methods available, anchor bolts provide a reliable and effective solution for a wide range of construction and industrial applications.
