Overview

The ABB - Installation Products Belleville Spring Washer Plus Flat Washer (SKU: 60803B) is a precision-engineered fastening solution designed for industrial applications requiring consistent tension, vibration resistance, and load distribution. This dual-component washer combines a Belleville (conical) spring washer with an outer diameter of 13/16 inch and a flat washer with an outer diameter of 1-1/4 inch, engineered for a 1/2-inch bolt size. The Belleville washer provides dynamic spring force to maintain tension under vibration and thermal cycling, while the flat washer ensures uniform load distribution and surface protection. The conical design on the Belleville side contacts the bolt head or nut, preventing loosening in dynamic environments such as machinery, automotive assemblies, and construction equipment. The 18-8 stainless steel construction (Type 18-8) delivers corrosion resistance and durability in harsh conditions, including exposure to moisture, chemicals, and temperature fluctuations. This washer eliminates the need for additional locking mechanisms in many applications, reducing assembly complexity and cost. Compatible with standard 1/2-inch bolts, it integrates seamlessly into existing fastening systems. Ideal for securing panels, machinery components, and structural connections where reliability and long-term performance are critical. The product is distributed by Gross Automation and carries the UNSPSC code 31161825.
