Simpson Strong-Tie Anchor Systems page for Titen HD.
The Titen HD® anchor is a patented, high-strength screw anchor for concrete and masonry. It is designed for optimum performance in both cracked and uncracked concrete; a requirement that the 2006 IBC places on post-installed anchors. The high-strength, easy-to-install Titen HD anchor has been tested and shown to provide outstanding performance in cracked and uncracked concrete under both static and seismic loading conditions. The self-undercutting, non-expansion characteristics of the Titen HD anchor make it ideal for structural applications, even at reduced edge distances and spacings. Recommended for permanent dry, interior, non-corrosive environments or temporary outdoor applications.
INSTALLATION
Holes in metal fixtures to be mounted should be 1/8" oversized for material thicker than 171 mil (7 ga). Use 1/16" oversized holes for material 171 mil (7 ga) and thinner.
Caution: Oversized holes in the base material will reduce or eliminate the mechanical interlock of the threads with the base material and will reduce the anchor's load capacity. Use a Titen HD screw anchor one time only. Installing the anchor multiple times may result in excessive thread wear and reduced load capacity.
- Drill a hole in the base material using a carbide drill bit the same diameter as the nominal diameter of the anchor to be installed. Drill the hole to the specified embedment depth plus 1/2" minimum 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 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.
- If the anchor will not install completely, remove the anchor and assure that all dust has been evacuated or drill the hole deeper. Begin re-installation of the anchor by hand to prevent cross-threading.
- Do not use impact wrenches to install into hollow CMU.

SUGGESTED SPECIFICATIONS
Screw anchors shall have 360-degree contact with the base material and shall not require oversized holes for installation. Fasteners shall be manufactured from carbon steel and are heat-treated. Anchors shall be zinc-plated in accordance with ASTM B633 or mechanically galvanized in accordance with ASTM B695. Anchors are not to be reused after initial installation. Screw anchors shall be Titen HD® anchors from Simpson Strong-Tie, Pleasanton, CA. Anchors shall be installed per the Simpson Strong-Tie instructions for the Titen HD anchor.
*Some jurisdictions require an additional square-plate washer for sill-plate applications.

Shear and Tension Loads Attaching Cold-Formed Steel To Normal-Weight Concrete
SEISMIC VALUES: IBC Section 1908.1.16 requires that concrete anchors in Seismic Design Categories C through F be governed by the strength of a ductile steel anchor. Alternately, for anchor solutions limited by the concrete capacity, the IBC requires that either the attachment to the structure shall undergo ductile yielding at a load level less than the anchor design capacity, or the anchor strength shall be at least 2.5 times the demand force.
- Seismic tabulated values are for cracked concrete; an adjustment factor of 0.75 is assumed per ACI 318 Section D.3.3.3 for SDC C through F. See note above regarding SEISMIC VALUES.
- Converting LRFD to ASD assume LRFD values divided by 1.4 and 1.6 for seismic and wind respectively.
- Shear load is applied parallel to the edge of concrete. Anchor is considered as an individual anchor without influence from other anchors
- Concrete shall have a minimum f’c of 2,500 psi. Reference ICC-ES ESR-2713 (PDF) for further information.
- CFS values are based on 2001 AISI NAS, Eq. E3.3.1-1 for shear (mf = 0.75, Ω = 2.5) and Eq. E4.4.2-1 for tension (Ω = 3.0, dw = 0.5”). Reference General Notes for CFS properties.
- Governing load is the lesser of Concrete and CFS.
- For conditions not covered by this table use Simpson Strong-Tie Anchor Selector™ Software for ACI 318.
- Wind tabulated values are for uncracked concrete without supplemental reinforcement. Wind design includes SDC A and B.
