Carbon steel self-clinching nuts are high-strength fasteners designed for thin metal sheet applications. Their self-locking embedded structure allows them to excel in fastening, vibration resistance, and tensile strength. To ensure the quality and durability of these fasteners, engineers conduct rigorous torque and tensile strength testing. These tests are critical indicators of their long-term stability and reliability in high-stress environments, ensuring the fasteners' safety and performance in real-world applications.Torque Testing: Ensuring Anti-Loosening and Self-Locking PerformanceImportance of Torque TestingTorque testing is a key step in evaluating the anti-loosening capabilities of carbon steel self-clinching nuts. Since the installation process involves embedding the nut into the metal surface to create a self-locking mechanism, torque testing ensures that the fastener does not loosen due to vibration or repeated loads during normal use. The test simulates the torque load these nuts will experience in actual applications to ensure their self-locking effect remains consistent.Testing ProcessTorque testing typically includes two aspects: installation torque and removal torque. Installation torque refers to the minimum torque required to install the nut, while removal torque refers to the force needed to loosen the nut from the hole. These parameters help ensure that the connection remains stable during both installation and removal, without over-tightening or dam
