Our Hexagon flange nut is designed for secure and vibration-resistant fastening in grooved pipe coupling systems. From one side, they resemble a standard hex nut for easy wrenching, while the bottom features a wide, integrated circular flange with a distinctive bell-like profile. The serrated underside bites firmly into the coupling housing, providing superior grip, preventing loosening, and ensuring even load distribution without the need for separate lock washers.
