FLANGE NUTS SUPPLIER EXPORTER IN CHINA
Ningbo Teng Qi Fasteners Co., Ltd is a professional flange nuts supplier in China. A flange nut, also known as a serrated flange nut or a spin lock nut, is a type of nut that features a wide, flat circular base or flange integrated into its design. This flange serves a specific purpose in various applications. Flange nuts are commonly used in situations where secure fastening is required, especially in applications with vibration or movement. The combination of a wide flange and serrations gives flange nuts their unique advantages in specific applications, providing a more secure and reliable fastening solution compared to standard nuts.

| Inspect Item | Detail |
|---|---|
| Dimensional Inspection | Critical dimensions such as bolt diameter, head width, head height, bolt length and thread length are checked using calibrated measuring equipment. Inspection is carried out according to the applicable dimensional standard or customer drawings to ensure consistent fit and interchangeability. |
| Thread Inspection | External threads are inspected using calibrated GO and NO-GO thread gauges to verify thread profile, pitch and dimensional conformity. Additional measurements can be performed when tighter thread tolerances or specific customer requirements apply. |
| Mechanical Testing | Mechanical properties are verified according to the specified material and strength grade. Depending on the applicable standard, testing may include tensile strength, yield strength, hardness and other required mechanical tests, with test results documented in the relevant inspection or material reports. |
| Surface & Coating Inspection | Bolt surfaces are inspected for appearance, defects, coating uniformity and other specified requirements. For coated fasteners, coating thickness and adhesion or other applicable coating characteristics can be checked according to the specified surface treatment standard. |
| Final Inspection & Testing | Before shipment, finished hex bolts undergo final inspection to confirm dimensions, thread quality, mechanical requirements, surface condition, marking and packaging. Inspection records and test reports can be provided according to the order specification and customer requirements. |
