A bolt is a threaded fastener with an external male thread, designed to be paired with a nut to secure multiple components together. Bolts feature a head (e.g., hex head, socket head, or countersunk) for tool engagement and a shank with partial or full threading. Key characteristics include:
Thread Type: Metric (ISO) or Imperial (UNC/UNF).
Strength Grade: Rated by property classes (e.g., 4.6, 8.8, 10.9, 12.9).
Material: Carbon steel, stainless steel (A2/A4), or alloy steel.
Surface Treatment: Zinc-plated, hot-dip galvanized, or Dacromet-coated for corrosion resistance.
Common applications include structural joints, machinery assembly, and automotive frameworks.
A nut is an internally threaded fastener that mates with a bolt to form a secure, load-bearing connection. Nuts are categorized by design and function:
Hex Nuts: Standard six-sided nuts for general use.
Lock Nuts: Equipped with nylon inserts or deformed threads to prevent loosening.
Flange Nuts: Integrated washer-like base to distribute load.
Wing Nuts: Hand-tightened for quick assembly.
Critical specifications include thread pitch, hardness (matched to bolt grade), and anti-corrosion coatings.
High Tensile Strength: Withstands dynamic loads and vibrations.
Standard Compliance: Manufactured to ISO, DIN, ANSI, or JIS standards.
Versatility: Adaptable to diverse industries (construction, aerospace, marine).
Note: Torque values and installation methods must align with engineering guidelines to ensure joint integrity.
For detailed technical data (dimensions, torque charts, or material certifications), consult the product datasheet or relevant standards (e.g., ISO 898, ASTM A194).
