The following is a description of the double layered self-locking washer:
Structural design: Crafted with precision, the Double Stack Self-Locking Washer showcases a sophisticated dual-layer system, where each metal washer is ingeniously engineered with a wedge-shaped or cam-shaped large tooth surface on one side and meticulously crafted radial fine teeth on the opposite. These formidable large tooth surfaces face each other, meticulously paired to ensure seamless interaction and superior performance.
Working principle: Ingeniously designed, when the bolt or nut is methodically tightened, the radial fine teeth on the washer dramatically boost the friction coefficient of the contact surface. In instances where the bolt shows a tendency to loosen, the strategic slip between the wedge-shaped teeth comes into play. Thanks to the wedge-shaped teeth's angle being greater than the thread lift angle, the washer thickens axially more than the thread's axial climb, thereby amplifying the bolt's axial preload. This ingenious mechanism effectively prevents loosening caused by vibration, ensuring optimal stability.
Material characteristics: Our washers are crafted from top-tier materials such as stainless steel, carbon steel, and other robust alloys. For stainless steel, we employ the superior EN1.4404 alloy, while EN1.7182 alloy is chosen for carbon steel gaskets. Additional premium-grade materials like S60c and 35CrMo high-quality special grade steel are also utilized, boasting exceptional resistance to high temperatures, moisture, and corrosion, ensuring longevity and reliability.
Product advantages: Our washers offer unparalleled safety performance, making them a top choice for preventing loosening due to vibrations and power loads. Their locking effect remains steadfast, impervious to lubrication influences, delivering a consistent and reliable performance regardless of the pre-tightening force applied. With temperature characteristics matching standard bolts/nuts, these washers are not only reusable but also provide remarkable control over pre-tightening force.
Application areas: The versatility of our washers makes them indispensable across a multitude of industries, including automotive, 3C, equipment, medical, aviation, and rail. They are crucial components in key fastening applications such as aircraft engines and fuselage structures, automotive chassis, engines, and other critical components. These washers are also pivotal in the connection and fastening of heavy machinery, electrical equipment, and the robust construction of bridges and ships, setting a gold standard in engineering excellence.
