S-91525A319 0.172" ID x 0.625" OD Oversized Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments due to 316 stainless steel construction, ideal for chemical exposure and marine applications.
• Enhanced load distribution with precise 0.172" ID and 0.625" OD dimensions, preventing surface damage and loosening under vibration.
• Exceptional durability and wear resistance from Rockwell B68 hardness, ensuring long service life in high-stress assemblies.
• Reliable fit for No. 8 screws, providing secure fastening and reducing installation errors in inch-system applications.
• Consistent thickness control between 0.050" and 0.080", maintaining uniform pressure and gap filling in varied setups.
• Compliance with strict environmental regulations including RoHS 3 and REACH, ensuring safe use in regulated industries.
• Versatile industrial suitability for demanding sectors like chemical processing, marine, and food equipment where corrosion resistance is critical.

Professional Applications & Engineering Value

Engineered for demanding industrial environments, these 316 stainless steel flat washers address common failure points like rust and chemical degradation. The high molybdenum content in 316 grade provides excellent resistance to chlorides and acidic conditions, making them ideal for marine hardware, chemical processing equipment, and food industry machinery. With a Rockwell B68 hardness, they maintain structural integrity under repeated loads, while the precise inch-system dimensions (0.172" ID x 0.625" OD) ensure perfect alignment with No. 8 screws, reducing assembly time and preventing galvanic corrosion in mixed-material joints. This combination delivers long-term reliability in applications where maintenance access is limited.

Specification Summary & Compliance

These flat washers conform to standard inch measurement tolerances with an inner diameter of 0.172", outer diameter of 0.625", and thickness ranging from 0.050" to 0.080". Manufactured from 316 stainless steel with a hardness of Rockwell B68, they are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards for hazardous substance restrictions.
