Simpson Strong-Tie CNW3/4-3/4-OST CNW 3/4 in. to 3/4 in. Oversized Thread Coupler Nut with Witness® Hole

The Simpson Strong-Tie® CNW coupler nut is designed to connect threaded rods to one another and to anchor bolts. These 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.

This Simpson product is designed for construction, connector, fastening, anchoring, and structural applications where dependable performance, durability, and jobsite-ready installation matter.
