S-92916A427 0.625" ID x 1.5" OD General Purpose Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance thanks to brass construction, ideal for humid or chemically aggressive environments
• Excellent load distribution with a 1.5" outer diameter, protecting surfaces and preventing fastener embedment
• Precise fit for 9/16" screws ensured by the 0.625" inner diameter, reducing installation errors and improving assembly reliability
• Enhanced durability and deformation resistance from Rockwell B60 hardness, maintaining performance under repeated stress
• Consistent thickness control (0.081-0.101") for uniform clamping force and vibration resistance in industrial assemblies
• Global compliance assurance with RoHS 3 and REACH standards, ensuring safe use in regulated markets and applications
• Long-term reliability in inch-system machinery, providing dependable performance without galvanic corrosion risks when paired with compatible metals

Professional Applications & Engineering Value

This brass flat washer is engineered to address critical challenges in industrial and mechanical assemblies where corrosion resistance and electrical conductivity are paramount. Its non-magnetic properties make it ideal for electronic and marine applications, while the Rockwell B60 hardness ensures it withstands vibrational forces and maintains clamp load without deforming. The precise 0.625" ID and 1.5" OD provide optimal load distribution, preventing surface damage to softer materials and extending the life of 9/16" screw fastenings. Commonly used in plumbing, electrical enclosures, and machinery requiring inch system components, this washer eliminates galvanic corrosion issues when used with stainless or steel fasteners, reducing maintenance costs and downtime.
