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.
