S-98049A118 1.031" ID x 2" OD Oversized Washers

Key Features & Benefits at a Glance

• Exceptional corrosion resistance from 17-4 PH Stainless Steel, ideal for harsh industrial environments and extending service life.
• Superior strength and durability with a Rockwell C40 hardness rating, ensuring the washer maintains its shape and function under high loads.
li>Precise dimensional fit with a 1.031" inner diameter designed specifically for 1" screw sizes, preventing misalignment and ensuring secure fastening.
• Optimal load distribution due to the 2" outer diameter and consistent 0.170-0.190" thickness, which helps protect surfaces and reduce point stress.
• Guaranteed material safety and compliance, meeting RoHS 3 and REACH standards for use in regulated and sensitive applications.
• Long-term reliability in demanding conditions, thanks to the material's precipitation-hardening properties that resist wear and deformation.
• Seamless integration into inch-system assemblies, providing a reliable and standardized component for maintenance and new builds.

Professional Applications & Engineering Value

This 17-4 PH Stainless Steel flat washer is engineered to solve critical challenges in industrial applications where corrosion, high stress, and long-term reliability are paramount. The precipitation-hardening stainless steel construction provides an excellent balance of high strength and corrosion resistance, outperforming standard stainless grades in aggressive environments like chemical processing, marine equipment, and heavy-duty machinery. The precise 1.031" ID ensures a perfect fit for 1" screw sizes, eliminating play and securing the joint against vibration loosening. Its robust 2" OD and controlled thickness effectively distribute clamping force, preventing surface damage and bolt embedment, which is crucial for maintaining the integrity of expensive components and structures.
