      <h2>WSWH-AB Anchor Bolts</h2>
      <p>WSWH-AB anchor bolts in 1" diameters offer flexibility to meet specific project demands. Inspection is easy; the head is stamped with a No-Equal&reg; symbol for identification, bolt length, bolt diameter, and optional &ldquo;HS&rdquo; for &ldquo;High-Strength&rdquo; if specified.</p>
      <p><strong>Material:</strong>High-Strength (HS) ASTM A193 Grade B7 </p>
      <p>An additional nut for template installation is provided
        with each WSWH-AB.</p>

      <h2>WSWH-HSR Extension Kit</h2>
      <p>WSWH-HSR allows for anchorage in tall stemwall applications where full embedment of a WSWH-AB into the footing is required. The head is stamped for identification like a WSWH-AB. Kit includes ASTM A193 Grade B7 high-strength rod with heavy hex nut fixed in place and high-strength coupler nut.</p>

Anchor templates are available to locate the Strong-Wall at inside face of 2x6 framing. Hot-dip galvanized anchor bolts are available. For coated reinforcing, refer to ACI 318-19 Section 20.5.2. </li>
