Wedge-All® - Mechanically Galvanized

The mechanical galvanized Wedge-All® is Simpson Strong-Tie’s name for their wedge anchor made from carbon steel and mechanical galvanized. The Wedge-All® wedge anchors that are mechanically galvanized are for use in solid concrete and should not be used in brick or block. The mechanical galvanization of the Wedge-All® wedge anchors provides better rust resistant than the zinc plated Wedge-All®, and are deemed acceptable for use with treated lumber.

Wedge-All® - Diameters and Lengths Mechanically Galvanized

The mechanically galvanized Wedge-All® wedge anchor come in eight different diameters from 1/4” to 1-1/4”. Each diameter is available in various lengths for use in different applications requiring deeper embedment or for use when thicker fixtures are being fastened. The mechanically galvanized Wedge-All® wedge anchor is set by turning the nut clockwise until the recommended torque values are reached.

Wedge-All® - Codes and Federal Specifications Mechanically Galvanized

The mechanically galvanized Wedge-All® wedge anchor meets Federal Specifications A-A1923A, Type 4.

Wedge-All® - Testing Criteria for Mechanically Galvanized

The mechanically galvanized Wedge-All® wedge anchors have been tested for tension and shear values under static loads, seismic and wind loading, combination loading and for both critical edge distance as well as from an unsupported edge under ICC-ES’s criteria for expansion anchors (ACO1).

Wedge-All® - Hole and Bit Size for Mechanically Galvanized

Wedge-All® wedge anchors that are mechanically galvanized require a hole to be drilled into the concrete that is the same diameter as the Wedge-All® being installed. Anchor size is equal to the hole size. The bit to be used must be a carbide bit the same diameter as the diameter of the mechanically galvanized Wedge-All® wedge anchor. For example, a hole for a 5/8” galvanized Wedge-All® wedge anchor must be drilled using 5/8” carbide tipped bit that meets ANSI standard B212-15-1994. Hole tolerance is critical. The hole must be drilled using a hammer type drill to achieve rated holding values. (See Chart 1.)

Wedge-All® - Hole in Fixture Mechanically Galvanized

The hole in the fixture needs to be larger than the diameter of the galvanized Wedge-All® anchor being installed when the hole is drilled with the fixture in place or when the galvanized Wedge-All® will be inserted through the fixture. For the mechanically galvanized Wedge-All® wedge anchor diameters from 1/4” to 3/4 ”, the hole in the fixture needs to be 1/16” larger. For Wedge-All® wedge of 7/8” to 1-1/4” in diameter, the hole in the fixture needs to be 1/8” larger. The bit or the galvanized Wedge-All® wedge anchor will not fit through a hole in a fixture that is the same size diameter as the galvanized Wedge-All® wedge anchor being used. (See Chart 1)

Wedge-All® - Wrench Size Mechanically Galvanized

The size of the wrench needed to tighten the nut when setting the mechanically galvanized Wedge-All® wedge anchor is determined by the diameter of the Wedge-All® that is being used. (See Chart 1)

Wedge-All® - Length Identification Mechanically Galvanized

Each galvanized Wedge-All® wedge anchor is stamped with a letter of the alphabet on the threaded end of the anchor to identify the length of the anchor after it has been installed in concrete. Each letter represents the range for every 1/2”, for example, the letter “K “represents a Wedge-All® wedge anchor length from 6-1/2” up to, but not including, 7”. This allows inspection of the mechanically galvanized Wedge-All® wedge anchor for the depth the anchor is installed in the concrete, i.e. by subtracting the length of the galvanized Wedge-All® above the surface of the concrete from the designation of 6-1/2” up to, but not including, 7”.

Wedge-All® Installation – Mechanically Galvanized

Remember, if the mechanically galvanized Wedge-All® wedge anchor is to be inserted through the fixture while the fixture is in place then the holes in the fixture need to be larger than the diameter of the galvanized Wedge-All® wedge anchor being installed (See Chart 1). Impact wrenches should not be used for installing the mechanically galvanized Wedge-All® wedge anchor. Take caution that the hole is not oversized because this will make it difficult to set the anchor and the holding values will be reduced.

1. With a hammer drill, drill a hole in the concrete using a carbide tipped bit that meets ANSI standards and is equal to the diameter of the mechanically galvanized Wedge-All® wedge anchor being installed. Drill the hole deep enough to allow the anchor to be inserted into the concrete the minimum embedment depth that each diameter of anchor requires. Drill the hole slightly deeper than the embedment depth of the anchor to allow any dust or debris from the drilling and installation process to fall.

2. Using compressed air, blow out the hole. Overhead applications do not have to be blown out with compressed air.

3. Place the nut and washer on the threaded end of the mechanically galvanized Wedge-All® wedge anchor so that the nut is flush with the top of the anchor. This protects the threads during installation. Insert anchor through the hole in the fixture and into the hole drilled into the concrete. Strike the anchor and nut with a hammer until the nut and washer are tight against the fixture.

4. With a wrench, turn the nut clockwise until tight to reach the recommended torque values for the diameter. Place the nut on the threaded end of the mechanically galvanized Wedge-All® wedge anchor being installed.
