Simpson Titen HD® Screw Anchor

Designed for use in cracked and uncracked concrete and uncracked masonry, the Simpson Titen HD Anchor is a high-strength carbon steel screw that offers low torque during installation. It features a zinc plated or mechanically galvanized finish. It’s ideal for dry, non-corrosive conditions or temporary outdoor applications. It also qualifies for static and seismic loading situations. It is threaded along its length to undercut the base material offering a higher load capability and vibration resistance.

The anchor has been heat-treated to create tip hardness for better cutting. It can be installed using a standard-size ANSI tolerance drill bit and cuts into concrete with 50 percent less torque than other anchors.

The anchor includes a hex-washer head for a cleaner installed appearance. No separate washer is necessary unless it is required by code.

It is easy to remove, so it’s ideal for temporary anchoring of formwork, bracing, or for applications where fixtures may be moved.

The anchor is available in four diameters –- 3/8-inch, 1/2-inch, 58-inch, and 3.4-inch. Each diameter is available in a number of different lengths so that it can be used for different embedment and fixture thickness.

To determine the proper length of anchor to use, add the thickness of the material being fastened to the minimum embedment of the diameter of the anchor being used. The length of the anchor is measured from underneath the head.

There is some information you need to know prior to installation. This includes:

  • Anchor Spacing
  • Minimum Edge Distance
  • Embedment Depth Of The Anchor
  • Drill Bit Requirements
  • Hole Size

Anchor Spacing

Spacing between the anchor and an unsupported edge is less than other types of anchors because the Titen HD anchor is not an expansion anchor and does not apply energy against the base material. As a result, the minimum spacing required for all diameters of the Titen anchor is 3-inches.

Minimum Edge Distance

Considered a post-installed concrete fastener, the Titen HD anchor needs to be located a minimum distance from an unsupported edge. Since this is not an expansion anchor, the minimum distance from an unsupported edge is 1-3/4-inches for all diameters.

Embedment Depth Of The Anchor

Post-installed inspection of the anchor can be performed in a snap because the length is stamped on the anchor’s head. Embedment depth of any particular anchor has to be calculated. To determine the depth, simply subtract the length of the anchor above the surface of the base material from the total length of the anchor.

Drill Bit Requirements

The drill bit used to drill the hole for the anchor must meet ANSI standards. Hole size is equal to anchor size. The diameter of the anchor being installed is equal to the hold diameter that is drilled into the base material. For example, if the Titen HD anchor is 3/8-inch, then the hole must be 3/8-inch.

Hole Size

Cutting the proper hole size is essential. With the Titen HD anchor, an oversized hole will cause the holding ability to be reduced or non-existent because the interlock between the threads and the base material is reduced. This anchor should be used only one time because the threads could wear and the holding ability could be reduced.

The hole drilled must be larger in diameter than the diameter of the Titen HD anchor. It is necessary to determine whether the anchor will fit properly through the fixture hole before the hole is drilled into the base material.

Refer to a chart that provides the diameter of the anchor, the recommended fixture, the hole diameter, and the wrench size before installation.

Installation

Items you will need for the installation include:

  • Titen HD heavy-duty screw anchor with the proper hole diameter
  • The proper wrench that is recommended for the hole diameter of the anchor being used.
  • Hammer Drill
  • Carbide Drill Bit that meets ANSI standards and is the same diameter as the anchor being used.
  • Compressed Air

The installation of the Titen HD Anchor is relatively simple and can be achieved in five steps.

  1. Use the hammer drill and carbide bit to drill a hole into the base material. The hole should be about a 1/2-inch longer than the length of the anchor.
  2. Use compressed air to clean the hole of dust and debris after cutting it.
  3. Align the hole in the fixture with the hole in the base material and then insert the Titen HD anchor through the fixture hole and into the hole in the base material.
  4. Use the wrench to turn the head of the anchor clockwise until it is secure against the fixture. If you are inserting the anchor into hollow CMU, don’t use an impact wrench to perform this step of the installation.
  5. If the anchor doesn’t install completely, remove it from the hole, make certain that all the dust is removed from the hole or drill the hole deeper so that the dust can settle below the anchor.  Re-install the anchor by hand to avoid cross threading from occurring.
