FAQ

Q: What materials are nuts made of? 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 maintain
regularly.
 
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.
