Purchase Wedge Anchors

Wedge-All® Stainless Steel

The stainless steel Wedge-All® wedge anchor sold by Simpson Strong-Tie’s, Inc. is the brand name for their wedge anchor made from stainless steel. The stainless steel Wedge-All® wedge anchor can be purchased in two grades of stainless steel: 304 and 316 stainless steel. The stainless steel Wedge-All® wedge anchor should not be installed in brick or block because it is designed for use in solid concrete only. The 304 stainless steel Wedge-All® wedge anchors provide excellent rust resistance and the 316 stainless steel Wedge-All® provides the best rust resistance.

Wedge-All® Diameters and Lengths

Both the 304 and 316 stainless steel Wedge-All® wedge anchor come in eight different diameters from 1/4” to 1-1/4”. Each diameter is available in different lengths for use in different applications requiring deeper embedment or for thicker fixtures being fastened. The stainless steel Wedge-All® wedge anchor is set by turning the nut clockwise until the recommended torque values are reached.

Codes and Federal Specifications

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

Wedge-All® Testing Criteria

The stainless steel 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 and from an unsupported edge under ICC-ES’s criteria for expansion anchors (ACO1).

Hole and Bit Size Stainless Steel

Wedge-All® wedge anchors that are stainless steel require a hole to be drilled into the concrete the same diameter as the Wedge-All® being installed. Anchor size is hole size. The bit to be used must be a carbide bit must be the same diameter as the diameter of the stainless steel 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 needs to be drilled using a hammer type drill to achieve rated holding values. (See Chart 1)

Hole in Fixture for Stainless Steel Wedge-All®

The hole in the fixture should be larger than the diameter of the stainless steel Wedge-All® anchor being installed if the hole is drilled with the fixture in place or if the stainless steel Wedge-All® will be inserted through the fixture. For the mechanically stainless steel 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 stainless steel Wedge-All® wedge anchor will not fit through a hole in a fixture the same size diameter as the stainless steel Wedge-All® wedge anchor being used. (See Chart 1)

Wedge-All® - Wrench Size Stainless Steel

The size of the wrench needed to tighten the nut and to set the stainless steel Wedge-All® wedge anchor is determined by the diameter of the Wedge-All® being used. (See Chart 1)

Wedge-All® - Length Identification Stainless Steel

Each stainless steel 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 would allow inspection of the stainless steel Wedge-All® wedge anchor as to the depth the anchor is installed in the concrete by subtracting the length of the stainless steel Wedge-All® above the surface of the concrete from the designation of 6-1/2” up to, but not including, 7”.

Wedge-All® Installation – Stainless Steel

Remember, if the stainless steel 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 stainless steel Wedge-All® wedge anchor being installed (See Chart 1). Impact wrenches should not be used for installing the stainless steel 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.

Stainless Steel Wedge-All®

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 stainless steel 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, this will 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 stainless steel 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, striking 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 in order to reach the recommended torque values for the diameter. Place the nut on the threaded end of the stainless steel Wedge-All® wedge anchor being installed.
