- THDSS stainless-steel screw anchor available in 1/4", 5/8" and 3/4" diameters, in addition to the 3/8" and 1/2" sizes
- Ideal for exterior or corrosive environments
- Less carbon steel, less expansion
- Installs with an impact wrench or by hand tool
- Code listed in IAPMO UES ER-493 (concrete) and ICC-ES ESR-1056 (masonry)
- Tested per ACI355.2 and AC193
- U.S. Patents: 8,747,042 and 9,517,519
- Type 316 and Type 304 stainless steel with carbon-steel lead threads
- Drill a hole in the base material using a carbide drill bit (complying with ANSI B212.15) with the same diameter as the nominal diameter of the anchor to be installed. Drill the hole to the specified minimum hole depth overdrill (see table below) to allow the thread tapping dust to settle, and blow it clean using compressed air. (Overhead installations need not be blown clean.) Alternatively, drill the hole deep enough to accommodate embedment depth and the dust from drilling and tapping.
- Insert the anchor through the fixture and into the hole.
- Tighten the anchor into the base material until the hex-washer head contacts the fixture.
|Titen HD Diameter (in.)||Wrench Size (in.)||Recommended Steel Fixture Hole Size (in.)||Min. Hole Depth Overdrill (in.)|
|Suggested fixture hole sizes are for structural steel thicker than 12 gauge only. Larger holes are not required for wood or thinner cold-formed steel members.|
|1/4||3/8||3/8 to 7/16||1/8|
|3/8||9/16||1/2 to 9/16||1/4|
|1/2||3/4||5/8 to 11/16||1/2|
|5/8||15/16||3/4 to 13/16||1/2|
|3/4||1 1/8||7/8 to 15/16||1/2|
- Holes in steel fixtures to be mounted should match the diameter specified in the table below if steel is thicker than 12 gauge.
- Use a Titen HD screw anchor one time only — installing the anchor multiple times may result in excessive thread wear and reduce load capacity.
- Do not use impact wrenches to install into hollow CMU.
- Oversized holes in base material will reduce or eliminate the mechanical interlock of the threads with the base material and reduce the anchor’s load capacity.
