Stainless steel flange nuts, serrated flange nuts, and counter (lock) nuts — precision-made fasteners for reliable, vibration-resistant connections Key benefits - Stable, reliable performance: Precision manufacturing ensures consistent dimensions and mechanical properties for repeatable, dependable fastening. - Vibration resistance: Flange design with an integrated washer spreads load and resists loosening under vibration; serrated flanges bite into mating surfaces to reduce rotation. - Corrosion resistance: Made from stainless steel for long-term durability in indoor and outdoor environments. - Secure locking: Counter/lock nuts provide an additional locking function to prevent back-off where extra security is required. What makes these nuts stand out - Flange nut: Acts as a nut with an integrated washer, distributing clamping force and reducing the need for separate washers; designed to minimize loosening from vibration. - Serrated flange nut: Precision serrations on the flange improve grip on the mating surface, creating a mechanical resistance to rotation without damaging the bolt head. - Counter (lock) nut: Engineered for professional, practical use as a locking element to secure threaded connections where movement or vibration is a concern. - Quality workmanship and reasonable, functional design for stable, practical use in assembly and maintenance. Function, compatibility, and performance - Function: Provide threaded fastening, load distribution, anti-loosening (flange and serrated), and secondary locking (counter nut). - Compatibility: Designed to be used with corresponding bolts and threaded components of the same specification and thread standard. - Material: Stainless steel construction for corrosion resistance and long service life. - Performance: Precision tolerances and robust flange/serration geometry deliver secure clamps, improved torque retention, and consistent assembly outcomes. Typical applications - Automotive and transportation: Securing brackets, panels, and components where vibration and movement occur. - Industrial machinery and equipment: Fastening housings, guards, and assemblies that require reliable clamping and anti-loosening properties. - Construction and installation: Structural connections, HVAC components, and outdoor fixtures where corrosion resistance and vibration resistance are needed. Practical notes - Use the appropriate matching bolt size and thread form for best performance. - Serrated flange nuts are best for metal-to-metal contact; avoid use on finished or plated surfaces where serrations could mar the surface. - For critical or dynamic applications, pair flange or serrated nuts with a counter (lock) nut where additional locking is desired. These stainless steel flange, serrated flange, and counter nuts deliver dependable fastening, improved resistance to vibration, and professional-grade reliability for a wide range of applications.
