Product Introduction
Bolts and nuts are fundamental fasteners used to join two or more components securely. A bolt is a cylindrical rod with external threads, often with a head (hexagonal, square, or round) for tightening. A nut is a small, typically hexagonal piece with internal threads that match the bolt’s, designed to screw onto it.
Made from materials like steel (for strength), stainless steel (corrosion resistance), brass (conductivity), or titanium (high strength-to-weight ratio), they suit diverse applications—automotive, construction, machinery, and electronics.
When tightened, the bolt and nut create clamping force, holding parts together. They come in standard sizes (metric or imperial) and thread types (coarse or fine), ensuring compatibility. Reusable and easy to install/remove, they’re indispensable for assemblies needing disassembly or adjustment, balancing reliability and practicality in countless industries.
- What materials are bolts and nuts made of?
Common materials: steel (strength), stainless steel (corrosion resistance), brass (conductivity), titanium (lightweight strength). - How to choose the right bolt-nut size?
Match thread type (metric/imperial) and diameter (e.g., M8 bolt with M8 nut). Check length for the material thickness being joined. - Why do bolts/nuts loosen?
Vibration, thermal expansion, or insufficient tightening. Use lock washers or thread-locking adhesives to prevent it. - What’s the difference between coarse and fine threads?
Coarse: faster to install, better for soft materials. Fine: higher clamping force, ideal for tight spaces. - Can bolts/nuts be reused?
Yes, if undamaged (no stripped threads or deformation). Replace if worn to ensure safety.
