Simpson Strong-Tie® coupler nuts are a tested and load-rated method to join threaded rod and anchor bolts. The Witness Hole® in each nut provides a means to verify when rods are properly installed. The positive stop feature helps ensure even threading into each end of the nut. The CNW exceeds the specified minimum tensile capacity of corresponding ASTM A36 bolts and threaded rod. HSCNWs meet and exceed the specified minimum tensile capacity of corresponding ASTM A449 bolts and threaded rod. Contact Simpson Strong-Tie for other coupler nut sizes.

Finish

  • Zinc plated

Installation

  • Tighten the two rods until each all-thread rod is visible in the Witness Hole. Any portion of thread visible in the Witness Hole is a correct installation.
  • Standard CNW for use with non-hot-dip galvanized all-thread rod only.
  • 5/8"- and 7/8"-diameter couplers available with oversized threads for installation to hot-dip galvanized bolts (order CNW5/8-5/8OST and CNW7/8-7/8OST). Note that only one side is oversized to accommodate HDG rods and bolts.
  • Some OST couplers are typically oversized on one end of the coupler nut only and will be marked with an "O" on the oversized side. Couplers may be oversized on both ends. Contact Simpson Strong-Tie to order.
