Simpson Strong-Tie CNW3/8 3/8" Coupler Nut w/ Witness Hole (3/8-16 UNC)
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.
