Key Features & Benefits at a Glance

  • Corrosion-resistant brass construction ensures long-lasting performance in harsh or humid environments, reducing maintenance costs.
  • Excellent electrical conductivity makes it ideal for electrical assemblies where grounding or current flow is critical.
  • Rockwell B60 hardness provides reliable durability and resistance to deformation under load.
  • Precise inch-system dimensions (0.099" ID x 0.188" OD) guarantee a secure fit for No. 2 screws, minimizing loosening and vibration issues.
  • RoHS 3 and REACH compliance assures adherence to strict environmental and safety regulations for industrial use.
  • Consistent thickness range (0.013-0.027") offers uniform load distribution and spacing in precision applications.
  • Non-magnetic properties of brass prevent interference in sensitive electronic or instrumentation setups.

Professional Applications & Engineering Value

This No. 2 brass flat washer is engineered to address common industrial challenges such as galvanic corrosion, electrical isolation, and fastener integrity. Its brass material naturally resists rust and oxidation, making it suitable for marine, plumbing, and outdoor applications where moisture is prevalent. The Rockwell B60 hardness ensures the washer maintains its shape under torque, preventing failure in high-vibration machinery or electrical enclosures. Additionally, the precise inner and outer diameters (0.099" ID and 0.188" OD) provide exact alignment with No. 2 screws, reducing the risk of assembly errors and enhancing the longevity of connected components in industrial washers and precision flat washers systems.

Specification Summary & Compliance

This washer adheres to standard inch-system measurements with an inner diameter of 0.099", outer diameter of 0.188", and thickness ranging from 0.013" to 0.027", designed for screw size No. 2. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and safe for various industrial applications.
