Design and Structure

Material and Its Advantages

Application Scenarios

Stainless steel external serrated lock washers feature a circular shape with sharp, evenly - spaced serrations on their outer edge. These serrations are the key to their anti - loosening function. When installed between a nut or bolt head and the workpiece, as the fastener is tightened, the serrations dig into the contacting surfaces. In machinery that operates under high vibrations, like industrial motors, the serrations bite firmly into the connected parts' surfaces. This creates multiple high - friction contact points, generating a substantial frictional force that resists the rotation of the fastener. The serrations are designed with a specific angle, usually around 45° - 60°, to ensure optimal gripping power. Compared to smooth - surfaced washers, the serrated design of these washers provides a significantly enhanced anti - loosening effect, making them particularly suitable for applications where dynamic loads or vibrations are present.

These washers are made from stainless steel, such as the commonly used 304 or 316 grades. Stainless steel offers excellent corrosion resistance. In environments with moisture, like in marine applications or outdoor equipment, the chromium in the stainless steel forms a passive oxide layer on the surface. This layer prevents rust and corrosion, ensuring the long - term integrity of the washers. Additionally, stainless steel provides good mechanical properties. It has sufficient strength and hardness to withstand the forces during installation and operation. For example, when used in high - torque applications, the stainless - steel washers can endure the stress without deforming or breaking, maintaining their anti - loosening function.

These washers find extensive applications across various industries. In the automotive industry, they are used to secure engine components. For instance, in the engine's intake manifold, where high vibration and temperature changes occur, the anti - loosening property of these washers ensures that the bolts remain tight, preventing air leaks and maintaining engine performance. In the construction of industrial machinery, such as conveyor belts and pumps, they are used to keep fasteners in place. These machines often operate under continuous vibration and heavy loads, and the stainless - steel external serrated lock washers help reduce maintenance frequency and ensure stable operation. In the electronics industry, they are used in the assembly of electronic enclosures to prevent screw loosening due to vibrations during transportation or operation.

Packing & Delivery

Bag Packaging

Carton Packaging

Fasteners can be packaged in durable plastic bags, which are available in various sizes to accommodate different quantities (e.g., small batches of screws, nuts, or bolts). The bags are typically sealed by heat or with a zipper to prevent moisture, dust, and loss of contents. This method is lightweight, cost-effective, and suitable for retail sales, small shipments, or situations where easy access to the fasteners is needed. Additionally, clear plastic bags allow for quick visual identification of the products inside.

For larger quantities or bulk transportation, cartons are commonly used. These are sturdy cardboard boxes, often reinforced with corrugated layers to provide protection against impact during handling and shipping. Fasteners in cartons are usually pre-packed in bags or separated by dividers to avoid friction and damage. Cartons can be labeled with product details (e.g., type, size, quantity) and are stackable, optimizing storage and logistics efficiency. This method is ideal for industrial orders, wholesale distribution, or long-distance transportation where durability is a priority.
