Fasteners are mechanical parts used for connecting and fixing components, which are indispensable in industrial production and daily life.
Common Types:
Threaded types: Bolts, nuts, screws, which achieve fastening through thread engagement, such as engine cylinder bolts in automobiles.
Pins: Cylindrical pins, conical pins, used for positioning or transmitting loads.
Rivets: Permanent connectors that cannot be disassembled.
Washers: Flat washers prevent scratches, while spring washers prevent loosening.
Application Scenarios:
Covering automotive manufacturing, construction engineering, electronic devices, aerospace, and other fields. Examples include high-strength bolts for steel structures and micro screws for circuit boards.
Purchase Considerations:
Focus on strength grades (e.g., 8.8-grade bolts), environmental adaptability (galvanized for rust prevention), and installation convenience (self-tapping screws eliminate the need for pre-drilling).
