Typical application areas of hexagonal flange bolts
1. Automotive industry (the largest application)
-Engine compartment: water pump, generator, manifold fixed, selected 8.8/10.9 grade, serrated flange, surface Dacromet/zinc nickel alloy, temperature resistant and corrosion-resistant.
-Chassis/Suspension: Steering and suspension connection, choose level 10.9, enlarged flange, optional fine teeth, impact and loosening resistance.
-Specification: Mainly M6-M12, commonly used in small series (GB/T 16674.1).
2. Construction Machinery and Agricultural Machinery
-Excavator bucket and boom: Grade 10.9/12.9, thickened flange (5-8mm), made of chromium molybdenum alloy steel, resistant to heavy load impact.
-Tractor/harvester gearbox: 10.9 speed, serrated flange, suitable for field bumps.
-Specification: M10-M20, enlarged series (GB 5789/GB 5790).
3. Chemical and Ocean Engineering
-Reactor and valve: 316 stainless steel (A4-70) or duplex steel, flange with sealing gasket, resistant to strong corrosion and low-pressure sealing.
-Seawater desalination/ship: 316L/super duplex steel, or Dacromet-coated carbon steel, salt spray resistance ≥ 1000 hours.
4. General Machinery and Steel Structures
-Machine tool and motor: 8.8 grade, smooth flange, surface oxidation/galvanizing, suitable for general loads.
-Lightweight steel structure/guardrail: 4.8/6.8 grade, galvanized carbon steel, cost-compatible.
5. High-end equipment and special scenarios
-Aerospace/wind power: titanium alloy (TC4) or nickel-based alloy (GH4169), lightweight, high temperature resistant, and creep resistant.
-Medical equipment: Titanium alloy (TA2), biocompatible, can be repeatedly disinfected.
