Hot-Dipped Galvanized Anchor Bolts from Concrete Fastening Systems

While the hot-hipped galvanized wedge anchor should never be installed into soft, hollow base materials, their hot-dipped galvanized coating is excellent for use in moist atmospheres. Environments where more rust resistance is required than the standard zinc plated wedge anchors can provide need an application that uses this type of protective coating. Although it is important to keep in mind that the hot-dipped galvanized wedge anchor bolts offer more rust resistance than the mechanically galvanized wedge anchor bolts, but not more than a stainless steel wedge anchor.

• The hot-dipped galvanized wedge anchor bolts come in diameters ranging from 3/8" to 1-1/4."
• Each diameter of hot-dipped galvanized wedge anchor bolt comes in a number of different lengths to allow for a wide range of material thickness that might need to be fastened. The 3/8" diameter comes in a shorter length of 2-1/4" while the longest length of 12" is available in diameters of 1/2", 5/8", 3/4", 7/8", 1" and 1-1/4".
• The holding values of a hot-dipped galvanized wedge anchor bolts.     
      The larger the diameter of hot-dipped galvanized wedge anchor bolt that is installed then the better the holding values will be. A 1/2" diameter hot-dipped galvanized wedge anchor bolt has more holding strength than a 3/8" hot-dipped galvanized wedge anchor bolt.
      Each diameter of hot-dipped galvanized wedge anchor bolt must be installed to a minimum depth to ensure minimum holding values in the concrete. The deeper a hot-dipped galvanized wedge anchor bolt is embedded into the concrete then the better the holding values.
      The harder the concrete is that the hot-dipped galvanized wedge anchor bolt is installed, then the better the holding values will be. Concrete hardness is measured in psi (pounds per square inch). For comparison purposes, it shows up in charts as 2000 psi, 3000 psi or 4000psi.
  
  
• A hole must be drilled into the concrete for the hot-dipped galvanized wedge anchor bolt to be installed.
• The hole should be drilled deeper into the concrete than the embedment depth of the hot-dipped galvanized wedge anchor bolt. A minimum of 1/2" deeper is required to ensure that the wedge anchor bolt will not bottom out in the hole and to allow space for any debris to fall that is created during the installation process.
• The hole that is drilled into the concrete for the hot-dipped galvanized wedge anchor bolt must be drilled using a hammer drill in the hammer mode and using a carbide tipped bit that meets ANSI standards. It is critically important that the drill bit meet ANSI standards because this will ensure proper tolerance between anchor diameter and hole diameter.
