Professional Applications & Engineering Value

This brass flat washer delivers critical engineering solutions where corrosion resistance and electrical conductivity are paramount. The copper alloy construction prevents rust in humid, marine, or chemical-exposed environments, while the flat washer design evenly distributes clamping force to prevent damage to soft materials or painted surfaces. With a 0.406" ID precisely matching 3/8" screw size requirements, it eliminates loosening from vibration in machinery, automotive, and electrical enclosures. The Rockwell B60 hardness ensures the washer maintains its form under torque, making it ideal for industrial applications requiring repeated disassembly and reassembly without deformation.

Specification Summary & Compliance

Manufactured to standard inch system dimensions with 0.406" inner diameter, 0.875" outer diameter, and thickness ranging 0.105-0.130". The brass flat washer conforms to standard thread fit requirements for 3/8" screws with consistent dimensional accuracy. Compliant with RoHS 3 (2015/863/EU) under exemption 6(c) for lead in copper alloy and REACH (EC 1907/2006) regulations as of 01/17/2023, ensuring adherence to environmental and safety protocols for industrial components.
