Stainless Steel Simpson Titen HD® Screw Anchor

In a previous blog we discussed the carbon steel Simpson Titen HD® Screw Anchor. We noted that the anchor was designed for dry, non-corrosive conditions. This particular anchor should not be used in moist conditions. The carbon steel is vulnerable to rust and can expand as much as ten times its original volume. This would result in the damage of concrete.

If you are looking for a screw anchor to be used on concrete in multiple types of environments including moist, then you should consider the Stainless Steel Simpson Titen HD® Screw Anchor.

So efficient to install and treated to be corrosion resistant, you can simply drill it. Drive it. Forget it.

Although the stainless steel Titen HD® Screw Anchor contains small amounts of carbon steel its presence has been minimized and yet allows the screw to cut clean, precise grooves in concrete or masonry. The actual amount of the carbon steel is too little to damage concrete if it should become corroded.

The stainless steel threads of the screw are serrated on the tip so that they undercut the concrete as the anchor is driven into the hole. This permits the threads to interlock with the concrete for a strong, secure hold.

The corrosion resistant properties of the anchor make it ideal for use in exterior, coastal, or chemical applications. That’s because of the grade of the stainless steel used in these anchors –- Type 316 and Type 304. These grades of stainless steel have the undercutting capability of heat-treated carbon-steel, but won’t rust.

This anchor can be used in a variety of applications for use in seating, catwalks, machinery, piping, railings, and more.

The grades of the stainless steel in the 300 category have different corrosion-resistant properties, making them ideal for an assortment of environments. When matched properly to the environment and the application, screw anchors made with this grade of stainless steel will resist corrosion and preserve their strength and reliability.

Stainless steel categorized as Type 316 is the best choice for applications in corrosive or extreme environments including salt water or when chemical or corrosive solutions appear.

Type 304 stainless steel Titen HD Screw Anchors is appropriate for less extreme conditions where the environment may be wet, moist or damp.

Type 316 Stainless Steel Titen HD® Screw Anchors would serve well in the following applications:

  • Wastewater Treatment Plant
  • Fertilizer Storage Buildings
  • Sill Plates in Coastal Environments
  • Marine and Port Restoration Projects
  • Light Rail Transportation
  • Parking Structures
  • Tunnels
  • Balconies in Coastal Environments
  • Outdoor Railings in Coastal Environments

Type 304 Stainless Steel Titen HD® Screw Anchors are ideal for:

  • Stadium Seating
  • Curtain Walls
  • Clean Rooms
  • Central Utility Plant Facilities
  • Food Processing Plants
  • Ledger Bolt For Decks
  • DOT Signs and Fixtures
  • Agricultural Facilities
  • Cooling Towers
  • Pulp and Paper Mills
  • Scaffolding
  • Parking Structures
  • Tunnels
  • Balconies
  • Refineries
  • Breweries
  • Wineries
  • Fencing
  • Outdoor Railings

You should probably review charts that provide design and construction information as well as charts that will help you in the installation of these anchors.

How To Install A Stainless Steel Titen HD® Screw Anchor

Prior to installing a Stainless Steel Titen HD® Screw Anchor, refer to the chart that supplies information on Titen HD diameters, proper wrench size to use in the installation, and the minimum depth of the hole in which the screw anchor will be installed.

Once you are aware of the proper diameter anchor, and wrench to use as well as the proper hole size and minimum hole depth for the installation, then you are ready to install the anchor.

Material you will need to perform the installation include:

  • Drill
  • Carbide drill bit that complies with ANSI standard B212.15
  • Wrench
  • Compressed air
  • The proper Stainless Steel Titen HD® Screw Anchor

The installation process is simple.

  1. Use the drill and carbide drill bit to drill the proper size hole depth. Over drill to allow the thread tapping dust to settle below the screw far enough down so that it doesn’t affect the screw.  Drill the hole deep enough to accommodate embedment depth and the dust.
  2. Allow the dust to settle and then blow it clean with compressed air.
  3. Insert the anchor through the fixture and into the hole.
  4. Tighten the anchor into the base material until the hex-washer head of the anchor contacts the fixture.

Things to consider when performing the installation:

  • Holes in steel fixtures should match the diameter specified in the chart.
  • Use a Stainless Steel Titen HD® Screw Anchor just one time. Using the anchor in multiple installations can cause severe thread wear and could reduce load capacity of the anchor.
  • Don’t use impact wrenches to install into hollow CMU.
  • Oversized holes in the base material can reduce or eliminate the mechanical interlock of the threads with the base material and could reduce the anchor’s load capability.
