TITEN® HD HEAVY DUTY SCREW ANCHOR FOR CRACKED AND UNCRACKED CONCRETE

AUTHORIZED SIMPSON STRONG-TIE DISTRIBUTOR

Code Listed for Cracked Concrete

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 2009 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.

FEATURES:
  • Tested per AC193 to ensure outstanding performance in both cracked and uncracked concrete
  • Higher load capacity and vibration resistance: Threads along the length of the anchor undercut the concrete and efficiently transfer the load to the base material.
  • Vibration and shock resistance: The mechanical interlock of the threads and the ratchet teeth on the underside of the head help prevent the anchor from loosening in vibratory conditions. The Titen HD anchor has been tested to 12.6 million vibratory cycles with no performance reductions.
  • Specialized heat treating process: Creates superior surface hardness at the tip to facilitate cutting, while at the same time not compromising ductility within the anchor body.
  • Less spacing and edge distance required: The anchor does not exert expansion forces on the base material.
  • Easy post-installation inspection: The head is stamped with the Simpson Strong-Tie® “≠” sign and the anchor length in inches.
  • Suitable for use in place of code anchor bolts.
  • No special drill bit needed: Designed to install using standard sized ANSI tolerance drill bits
  • Installs with 50% less torque: Testing shows that when compared to competitors, the Titen HD requires 50% less torque to be installed in concrete.
  • Hex-washer head: Requires no separate washer and provides a clean installed appearance.
  • Removable: Ideal for temporary anchoring (e.g. formwork, bracing) or applications where fixtures may need to be moved. Re-use of the anchor to achieve listed load values is not recommended.

Serrated teeth on the tip of the Titen HD® screw anchor facilitate cutting and reduce installation torque. New longer 1/2″ diameter Titen HD® anchors achieve sufficient embedment depth to develop tension loads equal to many Simpson Strong-Tie holdowns that specify a 5/8″ diameter anchor.

  • CARBON STEEL: ZINC PLATED

    Titen HD product data

    1. Zinc plating meets ASTM B633, SC1.
    2. Length is measured from the underside of the head to the tip of the anchor.

    CARBON STEEL: GALVANIZED

    titen hd product data - mechanically galvanized

    1. Mechanical galvanizing meets ASTM B695, Class 65, Type 1. Intended for some pressure-treated wood sill plate applications. Not for use in other corrosive or outdoor environments. See guidelines page for more corrosion information.

  • INSTALLATION:

    Holes in metal fixtures to be mounted should match the diameter specified in the table to the right.

    • 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.
    • Do not use impact wrenches to install into hollow CMU.

    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 reduce load capacity.

  • TEST CRITERIA:

    The Titen HD® anchor has been tested in accordance with ICC-ES AC193, ACI 355.2 and ICC-ES AC106 for the following:

    • Static tension and shear loading in cracked and uncracked concrete
    • Seismic and wind loading in cracked and uncracked concrete
    • Performance in uncracked masonry

    Anchor Fatigue Testing: Tested in accordance with ASTM E 488 for the effects of fatigue. 25% of the average ultimate load was applied to the anchor for 2 million cycles at a frequency of 15 Hz. Subsequent load tests showed no reduction in ultimate tension capacity.

    Vibratory Load Testing: A 150 lb. concrete block was suspended from a 3/8″ diameter anchor embedded at 1 1/2″ and vibrated for 12.6 million cycles at a frequency of 30 Hz and an amplitude of 0.0325 inches. Subsequent load test showed no reduction in ultimate tension capacity.
