Professional Applications & Engineering Value
This heavy-duty square washer is engineered to address common industrial challenges such as vibration-induced loosening and surface indentation. Made from 18-8 Stainless Steel, it offers excellent resistance to rust and corrosion, making it suitable for outdoor, marine, and chemical processing applications. The square design provides a larger bearing surface compared to round washers, effectively distributing load and preventing pull-through in soft materials. With a Rockwell B83 hardness and precise 1.063" ID, it ensures long-term reliability in structural assemblies, machinery, and construction projects where inch-system fasteners are standard. Its robust build minimizes maintenance needs and downtime, delivering consistent performance in high-stress environments.
Specification Summary & Compliance
This square washer features an inner diameter of 1.063", width of 2", and thickness range of 0.235" to 0.265", designed for use with 1" screw sizes in inch measurement systems. It is manufactured from 18-8 Stainless Steel with a hardness of Rockwell B83 to meet industrial strength requirements. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for various applications.
