S-91844A360 0.33" ID x 1" OD Curved Washers

Key Features & Benefits at a Glance

• Superior vibration resistance through curved design that maintains consistent pressure under dynamic loads
• Enhanced load distribution across 7/8" tube surfaces to prevent material deformation and connection failure
• Corrosion protection with zinc-plated steel construction for extended service life in harsh environments
• Durable performance backed by Rockwell B40 hardness rating for repeated use without deformation
• Precision compatibility with 5/16" screws and 0.33" ID for secure, reliable fastening applications
• Regulatory compliance meeting RoHS 3 and REACH standards for global industrial applications
• Optimal thickness range (0.050-0.070") providing flexibility for various compression requirements

Professional Applications & Engineering Value

This curved washer delivers critical engineering solutions for industrial applications where vibration-induced loosening and uneven load distribution compromise system integrity. The specifically engineered curvature creates spring-like tension that maintains consistent clamping force on 7/8" tubing systems, effectively preventing fastener back-off in high-vibration environments. Manufactured from zinc-plated steel with Rockwell B40 hardness, these washers withstand repeated compression cycles without permanent deformation, making them ideal for heavy machinery, automotive assemblies, and structural frameworks. The precise 5/16" screw compatibility ensures proper alignment while the curved profile compensates for surface irregularities, distributing loads evenly across the entire contact surface to prevent stress concentration and material fatigue.

Specification Summary & Compliance

This inch-system curved washer features precise dimensional specifications including 0.33" inner diameter, 1" outer diameter, and thickness ranging 0.050-0.070" to accommodate standard 5/16" screw applications. Manufactured to industrial standards with zinc-plated steel construction and Rockwell B40 hardness certification. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability for global industrial supply chains.
