How does material affect selection?A: Common materials are carbon steel, stainless steel, brass, and nylon. Carbon steel offers strength but rusts; stainless steel resists corrosion; brass is non-magnetic and anti-corrosive; nylon prevents loosening and vibration. Q: What's the difference between a nut and a bolt?A: Nuts have internal threads and pair with externally threaded bolts. Bolts pass through parts, and nuts secure them. Q: How to prevent nuts from loosening?A: Use lock nuts, apply thread - locking compounds, or add mechanical lock devices like spring washers. Q: How to prevent nuts from corroding?A: Pick corrosion - resistant materials (stainless steel, galvanized steel), apply anti - corrosion coatings, and maintainregularly. Q: How to choose nut size and specification?A: Match nuts to bolts. Consider bolt thread diameter, pitch, load, and space. Refer to standards or experts. Q: What tools for nut installation and removal?A: Use wrenches, sockets, impact wrenches. Torque wrenches for precise torque. Q: Are there special nuts for specific uses?A: Yes. Wing nuts for easy hand - tightening; flange nuts for high - vibration; hex socket nuts for compact fastening.
