CNW Allows fast visual check for correct all thread rod installation HSCNW High Strength Coupler Nut CNW Transition Coupler Nut Typical CNW Rim Joist Installation All-thread rod is correctly installed when visible through CNWs and HSCNWs witness holes. Standard CNWs and HSCNWs provide a positive stop to allow even bolt threading top and bottom. CNWs and HSCNWs are tested and load-rated coupler nuts. They can be used for extending anchor bolts, for example, through floor framing. CNWs meet and exceed the capacity of corresponding ASTM A36 bolts and threaded rod. HSCNWs meet and exceed the capacity of corresponding ASTM A193 Grade B7 bolts and threaded rods. Contact factory for other coupler nut sizes. FINISH: Zinc Plated. INSTALLATION: Tighten the two rods until each all-thread rod can be fully seen in the witness hole. CODES: See page 12 for Code Listing Key Chart. 1. Allowable loads may be increased as permitted on page 13. 2.Allowable loads shown are based on threaded rod allowable load. Blocking not shown for clarity
