  • Excellent for setting immediately
  • Can be loaded immediately
  • Simple to install. It can be set in a bottomless hole.

Simpson Wedge-All Wedge Anchor

This variation of Wedge Anchor is non-bottom-bearing and features a wedge-style expansion mechanism for use in solid concrete or grout-filled masonry. It is available in carbon steel with zinc or mechanically galvanized coating as well as Types 303/304 and 316 stainless steel.

It also includes:

  • One-piece, wrap-around clip that assures uniform holding capacity.
  • A chamfered threaded end to ensure easy starting of nut.
  • Availability in a variety of diameters and lengths.

Simpson Strong Bolt 2 Wedge Anchor – ICC Approved for cracked & uncracked Concrete

A wedge-type expansion anchor designed for optimal performance in cracked and uncracked concrete as well as uncracked masonry. The Strong-Bolt 2 is available in carbon steel, Type 304 and Type 316 stainless steel

This anchor is qualified for static and seismic loading conditions and is ideal for horizontal, vertical and overhead application. It can be used in minimum concrete thickness of 3-1/4-inches and has a lightweight concrete-over-metal deck thickness of 2-1/2-inches and 3-1/4-inches.  It fits standard fixtures and installs with a common drill bit and tools.

When first manufactured, all wedge anchors had a precise thread length for each different length anchor. However, the manufacturing process changed. As a result, wedge anchors now are made using different machines that allows longer thread lengths without increased costs.  Moreover, the bullnose on the wedge anchor has also been added in recent years.

Despite the fact that wedge anchors are now made using different machines, all wedge anchors are essentially the same. They are made of the same basic materials and have threads and a clip that wedges the anchor into concrete. While each manufacturers’ clip is slightly different, they all work similarly to offer the same results.

How to Install Wedge Anchors

The installation can be achieved in five easy steps.

  1. Use a hammer drill and carbide bit to drill a hole into the concrete. The diameter of the bit is the same as the diameter of the anchor being used. The carbide bit should meet ANSI standards to ensure that the hole size for the anchor is properly drilled. The hole should be drilled to a minimum of one anchor deeper or ½-inch deeper than a wedge anchor will penetrate. This permits space for debris to fall into the hole during installation.  The fixture can be used as a template. However, make sure that the holes in the fixture are large enough for the drill bit to fit through.
  2. Clean debris out of the hole using a wire brush, vacuum or compressed air.
  3. Place the washer on the wedge anchor, and then thread the nut on. It is essential that the nut is threaded so that the top of it is level with the top of the wedge anchor. This helps protect the threads from any damage that can occur when hammering the anchor into the hole.
  4. Insert the wedge anchor with the clip end first through the fixture and into the hole in the concrete. Use a hammer to hit the wedge anchor and nut until the washer and nut are snug against the base material or fixture. Make certain that there is a minimum of six threads below the surface of the concrete or fixture because the threads are required to set the wedge anchor in place.
  5. Tighten the nut with your finger securely and then use a wrench and turn the nut 3 to 5 times to the proper torque. This pulls the wedge anchor up, wedging the clop between the steel stud and the wall of the hole.
