Titen HD® Rod Coupler Screw Anchor

The Titen HD rod coupler screw anchor is designed to be used in conjunction with a single or multi-story continuous rod tie-down system. This anchor provides a fast and simple way to attach threaded rod to a concrete stem wall or thickened slab footing. Unlike adhesive anchors, the installation requires no special tool, cure time or secondary setting process; just drill a hole and drive the anchor.

Allowable (ASD) Tension Loads for Post-Installed Anchors into Uncracked Concrete for Wind Loads

Allowable (ASD) Tension Loads for Post-Installed Anchors into Uncracked Concrete for Wind Loads
  1. Allowable tension loads are based on the Strength Design provisions of ACI 318-14 and have been converted to Allowable Stress Design (ASD) levels by applying a 0.6 factor for Wind loads.
  2. Tabluated values are applicable to the conditions listed below. Refer to the Simpson Strong-Tie Anchor Designer™ software for other conditions.
    1. Minimum concrete compressive strength = 2,500 psi
    2. Uncracked concrete
    3. Dry concrete
    4. Periodic special inspection
    5. Maximum short-term temperature = 150°F
    6. Maximum long-term temperature = 110°F
  3. Tabulated values apply to design tension loads consisting of 100% wind loads.
