Hot-Dipped Galvanized Anchor Bolts Now Available 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.

Available Diameters

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 anchors bolts come packaged with the correct size and number of nuts and washers that are hot-dipped galvanized and will match-up with the threads on the anchor. Standard nuts and washer will not work with a hot-dipped galvanized wedge anchor bolt because the threads are manufactured differently to allow for the thick galvanized material.

Available Lengths

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".

Holding Values

The holding values of a hot-dipped galvanized wedge anchor bolts depend on the diameter of wedge anchor bolt being installed, the depth of embedment and the hardness of the concrete base material.

  • 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.

Hole Diameter

A hole must be drilled into the concrete for the hot-dipped galvanized wedge anchor bolt to be installed. The diameter of the hole is equal to the diameter of the hot-dipped galvanized wedge anchor bolt being installed. A 5/8" hot-dipped galvanized wedge anchor bolt requires a 5/8" drilled hole.

Depth of Hole

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.

Drilling Hole

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.
