S-93762A100 0.26" ID x 0.562" OD Reinforcing Sleeve Washers

Key Features & Benefits at a Glance

• Enhanced corrosion resistance through black-oxide steel coating, extending service life in humid or harsh industrial environments.
• Superior load distribution with precise 0.26" ID and 0.562" OD dimensions, preventing surface damage and loosening under vibration.
• Optimized sleeve design (0.317" OD, 0.225" height) provides secure alignment for 1/4" screws, reducing installation errors.
• Exceptional mechanical durability from Rockwell C35 hardness, resisting deformation under high clamping forces.
• Reliable thickness and height (0.090" thickness, 0.315" overall) ensure consistent spacing and fastener stability in repetitive assemblies.
• Heavy-duty performance in inch-system applications, compatible with standard 1/4" fasteners for seamless integration.

Professional Applications & Engineering Value

This black-oxide steel sleeve washer is engineered to address critical challenges in industrial assembly, such as galvanic corrosion and misalignment. The black-oxide surface treatment forms a protective layer that significantly reduces oxidation, making it ideal for automotive, machinery, and outdoor equipment exposed to moisture. Its sleeve design acts as a precise guide for 1/4" screws, minimizing cross-threading and ensuring accurate placement in tight-tolerance applications. With a Rockwell C35 hardness, the washer maintains structural integrity under dynamic loads, preventing fatigue in high-stress environments like construction and heavy equipment. By combining corrosion resistance with dimensional accuracy, this component enhances the longevity and reliability of bolted joints, reducing maintenance costs and downtime.
