Description

Qualified for static and seismic loading conditions
Thread design undercuts to efficiently transfer the load to the base material
No special drill bit required; designed to install using standard-sized ANSI tolerance drill bits
Hex-washer head requires no separate washer and provides a clean installed appearance
The THDSS has an innovative carbon-steel thread that effectively cuts the concrete while significantly limiting the amount of carbon steel in the anchor; less carbon steel, less expansion
Size: 5/8 in. x 6-1/2 in.
Made from Type 304 stainless steel
Caution: Use a Titen HD screw anchor one time only — installing the anchor multiple times may result in excessive thread wear and reduce load capacity
Quantity: 10

The Titen HD stainless-steel screw anchor for concrete and masonry sets the standard for when the job calls for installation in multiple types of environments. It is the ultimate choice to provide fast and efficient installation, combined with long-lasting corrosion resistance for an unsurpassed peace-of-mind. The THDSS is a state-of-the-art screw anchor solution that combines the corrosion resistance of Type 300 Series stainless steel with the undercutting ability of heat-treated carbon-steel cutting threads. Type 316 is the optimal choice for applications in corrosive or extreme environments such as salt water, or when chemical or corrosive solutions are present. Type 304 is a cost-effective solution for less extreme applications where the environment may be wet, moist or damp.

Installation

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

Caution

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.
Installation of concrete screw generally is influenced by many factors such as but not limited to, concrete compressive strength, type of aggregate, installation location, installation direction and tools used for installation.
