S-90068A029 0.305" ID x 0.781" OD Finishing Washers

Key Features & Benefits at a Glance

• Flush surface installation with an 82° countersink angle for seamless integration and reduced snagging in industrial assemblies
• Enhanced corrosion resistance from nickel-plated steel construction, extending service life in harsh or humid environments
• Precise fit for 1/4" screws with a 0.305" inner diameter, ensuring secure fastening and minimizing loosening risks
• Optimal load distribution due to the 0.781" outer diameter, reducing surface stress and preventing material damage
• Durable steel core providing reliable strength and stability for repetitive use in mechanical and structural applications
• Consistent dimensional accuracy in inch measurements, facilitating easy replacement and interchangeability in existing systems

Professional Applications & Engineering Value

This 82° countersunk washer is engineered to address common challenges in industrial fastening, such as achieving a smooth, flush finish while maintaining structural integrity. Made from nickel-plated steel, it combats corrosion in demanding settings like outdoor machinery, marine equipment, or chemical processing plants. The precise 0.305" ID and 0.781" OD ensure a snug fit with 1/4" screws, preventing misalignment and distributing loads evenly to avoid surface indentation. Ideal for applications in automotive, aerospace, and construction, these washers support flush mounting in panels, frames, and assemblies where protrusion is not acceptable, enhancing both safety and aesthetics.
