The CNW is designed to connect threaded rods to one another and to anchor bolts. These coupler nuts are designed to exceed the specified minimum tensile capacity of the corresponding bolts and threaded rod. All CNW coupler nuts feature a positive stop to help ensure even threading into each end of the nut and a Witness® hole as a means to verify when rods are properly installed.

Key Features

  • Couplers use a Witness hole to ensure proper installation
  • Positive stop feature that helps ensure proper thread engagement into each end of the nut on straight-through models

Finish

  • Zinc plated or uncoated

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.
  • For transition couplers, thread the coupler onto the larger rod first, and then thread the smaller rod into the coupler.
  • Standard CNW or HSCNW models for use with non-hot-dip galvanized all-thread rod only.

Options

  • Available in standard strength and high strength depending on corresponding rod in use
  • Couplers available with oversized threads on one end for installation on hot-dip galvanized bolts (add –OST to model for ordering)
  • OST couplers are typically oversized on one end of the coupler nut only and will be marked with an “O” on oversized side
