S-98029A115 0.594" ID x 1.188" OD Oversized Washers

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with black-oxide steel coating for extended service life in harsh industrial environments
• Superior load distribution across the 1.188" OD surface area to prevent joint loosening and material deformation
• Precision dimensional fit with 0.594" ID ensuring secure seating on 9/16" screws without play or misalignment
• Consistent thickness control between 0.177-0.187" for uniform pressure application and reliable assembly performance
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe global industrial applications
• Durable steel construction providing reliable mechanical strength for high-vibration and heavy-load scenarios
• Broad industrial compatibility with standard inch-system fasteners for maintenance, machinery, and structural applications

Professional Applications & Engineering Value

These black-oxide steel flat washers deliver critical engineering solutions where corrosion protection and load distribution are paramount. The black-oxide surface treatment creates a protective barrier against moisture, chemicals, and environmental exposure, significantly extending component life in outdoor equipment, marine applications, and industrial machinery. The precise 0.594" inner diameter ensures perfect alignment with 9/16" screws, eliminating gaps that could compromise joint integrity. With their substantial 1.188" outer diameter, these flat washers effectively distribute clamping force across wider surface areas, preventing surface damage to soft materials and maintaining bolt tension in high-vibration environments. The controlled thickness variation (0.177-0.187") guarantees consistent performance in automated assembly processes while meeting strict RoHS and REACH compliance requirements for international projects.
