Simpson Strong-Tie® coupler nuts are a tested and load rated method to join threaded rod and anchor bolts. "Witness" holes in the nut provide a means to verify when rods are properly installed. The positive stop feature helps ensure even threading into each end of the nut. CNW's meet and exceed the tensile capacity of corresponding ASTM A36 bolts and threaded rod. HSCNW's meet and exceed the 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.

For 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).
