Professional Applications & Engineering Value

This brass flat washer is engineered to address critical challenges in industrial fastening, where corrosion and material degradation can compromise system reliability. The brass material inherently resists rust and galvanic corrosion, making it perfect for plumbing, electrical, and marine applications. Its 0.26" ID and 0.562" OD provide optimal bearing surface for 1/4" screw size fasteners, distributing load evenly to prevent surface damage and maintain bolt tension. With a controlled thickness range of 0.030-0.050" and Rockwell B60 hardness, it ensures dimensional stability under vibration and thermal cycling, reducing maintenance needs in heavy-duty industrial settings while complying with stringent environmental directives.

Specification Summary & Compliance

This washer meets standard inch system dimensions with an inner diameter of 0.26", outer diameter of 0.562", and thickness ranging from 0.030" to 0.050", designed for use with 1/4" screws. It conforms to typical flat washer manufacturing tolerances and is made from brass with a hardness of Rockwell B60. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of restricted substances and safe for industrial applications requiring environmental responsibility.
