S-93762A600 0.51" ID x 0.875" OD Reinforcing Sleeve Washers

Key Features & Benefits at a Glance

• Enhanced Corrosion Resistance: Black-oxide steel finish provides reliable protection against rust and oxidation, extending service life in harsh industrial environments.
• Superior Load Distribution: Sleeve design with 0.875" OD and 0.120" thickness effectively spreads clamping force, preventing surface damage and joint loosening.
• Precision Fit for 1/2" Screws: 0.51" inner diameter ensures accurate alignment and secure fastening, reducing installation errors and rework.
• Exceptional Mechanical Strength: Rockwell C35 hardness offers excellent resistance to deformation under high-stress conditions, maintaining structural integrity.
• Optimized Sleeve Geometry: 0.566" sleeve OD and 0.215" sleeve height provide stable bearing surface and improved vibration resistance in dynamic applications.
• Dimensional Consistency: Manufactured to precise inch-system standards (0.335" overall height) for reliable interchangeability and assembly efficiency.
• Versatile Industrial Compatibility: Suitable for both standard and heavy-duty equipment where corrosion resistance and durability are critical.

Professional Applications & Engineering Value

This black-oxide steel sleeve washer addresses critical challenges in industrial assembly where corrosion and mechanical stress compromise fastener performance. The sleeve design with precise 0.51" ID creates an optimal interface for 1/2" screws, eliminating misalignment issues while the extended bearing surface (0.875" OD) prevents embedment in soft materials. The Rockwell C35 hardness ensures the washer maintains its shape under repeated loading cycles, making it ideal for heavy-duty applications in construction machinery, agricultural equipment, and automotive assemblies. The black-oxide coating provides essential corrosion protection without dimensional changes, solving common galvanic compatibility problems in mixed-material structures. Engineers specify this precision washer for applications requiring reliable vibration resistance and long-term fastener integrity.
