Carbon Steel Spring Washers
Pengenalan produk
Carbon steel spring washers are essential fasteners that achieve anti-loosening through elastic deformation. Manufactured from premium materials like 65Mn and 70# carbon steel, they undergo quenching and tempering to ensure excellent elasticity and fatigue resistance. Their distinctive open-coil structure generates axial tension when the nut is tightened, continuously applying pressure to connected components and effectively counteracting loosening caused by vibrations, impacts, or other external forces. Surface treatments such as galvanization, black oxide coating, or Dacromet significantly enhance rust resistance, making them suitable for indoor and outdoor applications, including mechanical assembly, construction steel structures, and automotive chassis, especially in heavy-duty and high-vibration environments. The anti-loosening principle relies on elastic compensation under dynamic stress, and when combined with flat washers and bolts, it greatly improves the reliability of fastening systems.
Available in a full range of sizes from M3 to M30, these washers are produced in strict compliance with international standards such as GB/T 93 and ISO 7093, ensuring precise matching of parameters like elastic coefficient, free height, and opening size. The cost-effectiveness of carbon steel makes them a top choice in the industrial sector: 65Mn steel washers balance strength and flexibility for most mechanical connections, while Dacromet-coated variants withstand humid and mildly corrosive conditions with superior salt spray resistance. During installation, proper washer sizing and adherence to specified torque values are crucial for optimal anti-loosening performance. As indispensable safety components in mechanical fastening, carbon steel spring washers provide reliable solutions for various engineering projects, combining stable performance with economic efficiency.
