Professional Applications & Engineering Value

This 316 stainless steel square washer is engineered to address critical challenges in demanding environments where corrosion, chemical exposure, and mechanical stress are prevalent. The square shape provides a larger bearing surface compared to round washers, effectively distributing load and preventing embedment into soft materials or surfaces. Made from 316 stainless steel, it offers exceptional resistance to chlorides and acidic conditions, making it ideal for marine, chemical processing, and outdoor industrial applications. The precise 0.285" ID ensures a snug fit on 1/4" screws, reducing vibration-induced loosening and maintaining assembly integrity. With its Rockwell B68 hardness, this washer withstands high clamping forces without deforming, delivering long-term reliability in heavy-duty fastening systems.

Specification Summary & Compliance

This square washer meets precise dimensional requirements with an inner diameter of 0.285", width of 2", and thickness ranging from 0.056" to 0.063". It is designed for use with 1/4" screw sizes in inch-based measurement systems. The manufacturing ensures consistent Rockwell B68 hardness for mechanical reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, including the latest SVHC updates, confirming its safety and environmental responsibility for global industrial use.
