lindapter fasteners: Anti-loosening washers are a type of fastener with a flat circular ring shape. Placed between the bearing surface of a bolt, screw, or nut and the surface of the connected part, they increase the contact surface area of the connected parts, reduce pressure per unit area, and protect the surfaces of the connected parts from damage. Another type, elastic washers, also prevents nuts from loosening. The anti-loosening washer consists of two pieces. Its unique embedded structure changes the traditional method where anti-loosening relies mainly on friction, instead adopting the most advanced international anti-loosening technology, utilizing the tension between the two washers to achieve the dual effect of anti-loosening and locking. It prevents loosening caused by vibration and dynamic loads, is easy to disassemble, and the loosening torque is greater than the tightening torque; the locking effect is not affected by lubrication, and increased lubrication improves the anti-loosening effect; it has the same temperature characteristics as standard bolts/nuts; and can be reused a limited number of times.

lindapter fasteners functions

Anti-loosening washers bring convenience to the mechanical industry, as they can prevent thread loosening. There are many varieties of anti-loosening washers, including butterfly washers, saddle washers, spring washers, wave spring washers, etc., collectively known as anti-loosening washers. These types of anti-loosening washers rely on increasing static friction to achieve anti-loosening effects. Under conditions of low vibration, light load, and uniform speed, the anti-loosening effect can meet enterprise needs. However, under strong vibration, high load, and rapid motion conditions, they cannot achieve complete anti-loosening, only extending the time for nuts and bolts to loosen spontaneously. This breaks away from the previous method of achieving anti-loosening by increasing "preload" and enhancing "friction." The latest anti-loosening principle is applied not only in washers but also in nuts and bolts, thereby solving the problem of fastener loosening in heavy industry enterprises and eliminating the cumbersome installation process that previously required referencing input and output torques.

lindapter fasteners installation requirements

Anti-loosening washers are characterized by simple installation. Simply place the two washers with their inner inclined tooth surfaces facing each other between the nut and the connected material. After the nut is tightened, the outer radial cambered surface of the anti-loosening washer bites into the contact surfaces at both ends, and the angle of the inner inclined tooth surface is greater than the thread angle of the bolt. When the bolt is elongated due to mechanical vibration, the nut will rotate and loosen. Since the friction on the outer radial cambered surface of the anti-loosening washer is greater than the friction between the inner inclined tooth surfaces, in this state, only relative sliding between the inner inclined tooth surfaces is allowed, generating a certain lifting tension. When the bolt contracts, the inclined tooth surfaces of the washer return the nut to its original position. Thus achieving 106% anti-loosening and locking effects. The washers are suitable for relatively flat and smooth surfaces. If the connected material is non-metallic, a metal plate can be fixed to the connected material to allow the use of anti-loosening washers.

lindapter fasteners applications

Due to different environments, the material requirements for anti-loosening washers vary. They are characterized by a wide variety of specifications, diverse performance and uses, and a high degree of standardization, serialization, and generalization. Some people refer to anti-loosening washers that already have national standards as standard fasteners or simply standard parts. Stainless steel anti-loosening washers have inherent corrosion resistance; when the surface is damaged, a thin oxide layer forms on the metal surface to prevent further rusting. Typically, this series of actions—blocking, shearing, adhesion, and locking—occurs within just a few seconds, so correct understanding and use of these fasteners is necessary to prevent this phenomenon. Anti-loosening washers are suitable for equipment subject to frequent vibration, such as: automotive industry, compressors, construction, wind power generation equipment, agricultural machinery, casting industry, drilling equipment, shipbuilding industry, mining equipment, oil drilling rigs (onshore or offshore), public utilities, rail transit, transmission systems, and metallurgical equipment.
