Our ANSI heavy hexagon nut is engineered to pair with ANSI oval neck track head bolts in grooved pipe coupling systems. These robust nuts feature a wider across-flats design and thicker profile for superior wrench grip and torque distribution. When tightened, they securely clamp the grooved coupling housing halves together, exerting uniform pressure on the elastomeric gasket to create a reliable, leak-tight seal.
