A nut is a standardized component used in conjunction with a bolt or screw to fasten and connect mechanical parts. Its core characteristic is its internal thread, which engages with the external thread to achieve connection and locking.
Main characteristics include:
Fastening Function: Securely connects two or more components through threaded engagement, making it one of the most basic "connectors" in mechanical assembly.
Standardized Design: Complies with international standards such as GB, DIN, and ANSI/ASTM, ensuring interchangeability and universality.
Diverse Structural Forms: Common types include hexagonal nuts, square nuts, flange nuts, slotted nuts, wing nuts, and cap nuts, adaptable to different installation spaces and functional requirements.
Various Material Options: Depending on the application environment, materials such as carbon steel, stainless steel (e.g., 304), copper alloys, and aluminum alloys are available, offering varying strengths, corrosion resistance, and electrical conductivity.
Reusable Disassembly and Reassembly: Most nuts support multiple disassembly and reassembly, facilitating maintenance and adjustment.
Anti-loosening design: Some nuts have anti-loosening functions, such as nylon insert nuts, flange toothed nuts, slotted nuts with cotter pins, etc., to prevent loosening in vibration environments.
