S-94051A232 0.812" ID x 1.5" OD ASME B18.21.1 General Purpose Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance thanks to titanium construction, ideal for harsh industrial environments and chemical exposure
• Enhanced durability and load distribution with a Rockwell B80 hardness rating, reducing surface damage and extending assembly life
• Precise fit for 3/4" screws with a 0.812" inner diameter, ensuring secure fastening and minimizing loosening under vibration
• Optimal surface coverage and stability from the 1.5" outer diameter, providing excellent support for larger bolt heads and nuts
• Reliable dimensional consistency with a thickness range of 0.108-0.160", meeting stringent ASME B18.21.1 specifications for flat washers
• Environmental and workplace safety compliance with RoHS 3 and REACH regulations, ensuring no hazardous substances are used
• Long-term cost efficiency due to titanium's excellent strength-to-weight ratio and resistance to wear and galling

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these titanium flat washers address critical challenges like galvanic corrosion in marine, aerospace, and chemical processing equipment. The titanium material provides an exceptional strength-to-weight ratio while resisting pitting and crevice corrosion, which is vital for assemblies exposed to saltwater, acids, or high humidity. With a Rockwell B80 hardness, the washer maintains its form under high clamp loads, preventing embedding into softer materials and ensuring consistent preload in bolted connections. The compliance with ASME B18.21.1 guarantees that dimensions and tolerances are controlled for reliable performance in heavy-duty machinery, pressure vessels, and structural frameworks, reducing maintenance downtime and replacement costs.
