S-91525A339 0.625" ID x 1.375" OD Oversized Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance from 316 stainless steel material, ideal for harsh chemical and marine environments
• Precise dimensional fit with 0.625" ID and 1.375" OD ensuring proper alignment and load distribution for 9/16" screws
• Enhanced durability with Rockwell B68 hardness providing excellent wear resistance and long service life
• Consistent thickness control (0.110-0.140") for uniform pressure distribution and reliable joint integrity
• Environmental compliance with RoHS 3 and REACH standards for safe use in regulated industries
• Heavy-duty performance capable of withstanding high mechanical stress in demanding industrial applications
• Broad compatibility with inch-system fasteners and equipment for seamless integration into existing assemblies

Professional Applications & Engineering Value

These 316 stainless steel flat washers deliver exceptional value in applications where corrosion resistance and chemical stability are paramount. The marine-grade composition provides reliable performance in saltwater environments, chemical processing plants, and food processing equipment where ordinary washers would rapidly deteriorate. The precise 0.625" inner diameter ensures perfect fitment with 9/16" screw sizes, preventing misalignment while the generous 1.375" outer diameter distributes clamping force effectively across wider surfaces. This combination addresses common engineering challenges including galvanic corrosion, joint loosening due to vibration, and surface damage to expensive components. The Rockwell B68 hardness maintains dimensional stability under heavy loads, making these industrial washers suitable for structural applications, machinery assembly, and heavy equipment maintenance where reliability cannot be compromised.
