• Optimal Load Distribution: The 1.156" outer diameter provides a larger bearing surface to effectively distribute load and prevent surface damage.
• Versatile Thickness Range: With a thickness of 0.074-0.121", it offers flexibility for fine-tuning assembly gaps and tension.
• SAE Standard Compliance: Manufactured to SAE standards, ensuring reliable interchangeability and performance in inch-based systems.
• Environmentally Responsible Sourcing: Compliant with RoHS 3 and REACH regulations, making it suitable for global supply chains with strict environmental standards.
• Broad Industrial Application: Ideal as a general-purpose, non-hardened washer for applications where high hardness is not a critical requirement.

Professional Applications & Engineering Value

This SAE flat washer is engineered to solve common industrial challenges such as surface marring, loosening due to vibration, and galvanic corrosion. Its aluminum construction makes it an excellent choice for lightweight assemblies in the automotive and aerospace sectors, where every ounce matters. The precise 0.594" ID ensures a snug fit on 9/16" screws, maintaining bolt alignment and clamping force. The 1.156" OD effectively spreads the load over a wider area, protecting soft or finished surfaces from damage. This combination of a corrosion-resistant material and a compliant flat washer design provides long-term reliability in environments exposed to moisture and chemicals, reducing maintenance needs and replacement costs.
