S-91525A124 0.281" ID x 1.25" OD Oversized Washers

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments due to 316 stainless steel construction
• Precise fit for 1/4" screws with 0.281" inner diameter ensuring secure fastening
• Optimal load distribution provided by the large 1.25" outer diameter surface area
• Consistent performance maintained through controlled 0.040-0.060" thickness variation
• Environmental compliance assurance with RoHS 3 and REACH regulatory standards
• Long-term reliability in demanding industrial applications without hardness degradation concerns
• Seamless inch-system compatibility with existing North American equipment and specifications

Professional Applications & Engineering Value

These 316 stainless steel flat washers deliver exceptional value in corrosive environments where standard fasteners fail. The inch-system washers with precise 0.281" ID ensure perfect alignment with 1/4" screws, preventing misalignment and thread damage during assembly. The generous 1.25" OD provides superior load distribution across softer materials or painted surfaces, reducing surface deformation and maintaining structural integrity. Particularly valuable in marine applications, chemical processing equipment, and food processing machinery, these corrosion resistant washers withstand chlorides, acids, and extreme temperatures that compromise ordinary fasteners. The controlled thickness tolerance (0.040-0.060") ensures consistent clamping force in automated assembly processes, making them ideal for industrial washers applications requiring repeatable performance and regulatory compliance.

Specification Summary & Compliance

Manufactured to standard inch-system dimensions with 0.281" inner diameter, 1.25" outer diameter, and 0.040-0.060" thickness range for 1/4" screw applications. These flat washers comply with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations concerning chemical substances. The 316 stainless steel composition provides inherent corrosion resistance without additional surface treatments, ensuring consistent performance across temperature variations and environmental exposures.
