Frequently Asked Questions
- How do I know when the threaded rods are properly installed in this coupler nut?
- The CNW7/8-5/8 features a Witness hole that allows you to visually verify proper installation. Tighten the two rods until each all-thread rod is visible through the Witness hole, confirming that both rods are fully and evenly engaged within the nut.
- What rod sizes does the CNW7/8-5/8 coupler nut accommodate?
- This coupler nut is designed to connect a 7/8 in. diameter threaded rod on one end to a 5/8 in. diameter threaded rod on the other end, making it ideal for transition connections between two different rod sizes.
- Can this coupler nut be used with hot-dip galvanized all-thread rod?
- No. The CNW7/8-5/8 is designed for non-hot-dip galvanized all-thread rod only. For use with hot-dip galvanized bolts, Simpson Strong-Tie offers OST models that feature oversized threads on one end to accommodate the thicker galvanized coating.
- What is the purpose of the positive stop feature on the CNW coupler nut?
- The positive stop is an internal feature built into the coupler nut that helps ensure even threading into each end of the nut. It acts as a centering mechanism so that both threaded rods engage with consistent and balanced thread depth, supporting the nut's ability to meet or exceed the specified minimum tensile capacity of the corresponding bolts and threaded rod.
