Anchor Bolt

• General Info

  An anchor bolt is a type of fastener used to attach objects or structures to concrete. They are typically made from heavy-duty metal, like stainless steel, and are commonly used in construction, manufacturing, and various engineering applications to secure structural elements such as beams, walls, or heavy machinery.

• Specification

  Material Composition
  Carbon steel: commonly used due to its strength and affordability.
  Stainless steel offers excellent corrosion resistance, ideal for outdoor or corrosive environments.
  High-Strength Alloys: Used in applications where greater strength is needed, such as high-load or seismic applications.
  
  Grade and Strength
  Anchor bolts are typically graded by their yield and tensile strength:
  ASTM A307: Standard grade for general construction; low carbon steel bolts.
  ASTM F1554 Grade 36, 55, and 105: Specifies the minimum yield strength in ksi (e.g., Grade 36 has 36 ksi).
  ASTM A325 and A490: High-strength grades often used in structural steel connections.
  AISI 304/316 Stainless Steel: Used for corrosion resistance, particularly in marine environments.
  
  Bolt Dimensions
  Diameter: The diameter varies from 1/4" up to several inches, depending on the application.
  Length: Length depends on the thickness of the material being fastened and the depth of the concrete; commonly ranges from 3" to 36" or longer.
  Thread Length: Specifies the length of the threaded portion, which allows for nuts and washers to be attached.
  
  Type of Head and End Configuration
  L-shaped anchor bolts: common for cast-in-place applications in concrete foundations.
  Straight Anchor Bolts: often used with adhesive anchors.
  Headed Anchor Bolts: Include a nut head, hex head, or welded washer head to resist pull-out forces.
  
  Coatings and Finishes
  Plain/Uncoated: Suitable for indoor or non-corrosive environments.
  Hot-Dip Galvanized: Adds corrosion resistance; suitable for outdoor environments.
  Zinc Plated: Offers limited corrosion resistance, mostly used for indoor applications.
  Epoxy-coated or fluoropolymer coatings provide excellent corrosion resistance, particularly in harsh industrial or marine environments.
