Product Description

Black - plated wave washers feature a unique, wavy profile that sets them apart from other types of washers. 

Structural Design and Function

Black Plating Benefits

Material and Specification Range

Black - plated wave washers feature a unique, wavy profile that sets them apart from other types of washers. These washers are circular in shape with a series of evenly - spaced waves or undulations running along their circumference. When installed between two components, such as a bolt head and a workpiece or between two machine parts, the wave - like structure allows the washer to compress and expand under load. This compression generates a spring - like force. For example, in a motor assembly, the black - plated wave washer provides a continuous pre - load on the bearing, ensuring that the components remain firmly in place while also compensating for any minor movements or vibrations during operation. This not only helps in maintaining the proper alignment of the parts but also extends the service life of the overall assembly.

The black plating on these wave washers offers several significant advantages. Firstly, it serves as an effective corrosion - resistant barrier. The plating process deposits a thin, yet durable, layer of material on the surface of the washer. This layer protects the underlying metal from exposure to moisture, oxygen, and other environmental elements that could cause rust and corrosion. In outdoor applications, such as in the construction of bridges or outdoor machinery, where the washers are constantly exposed to rain, humidity, and temperature fluctuations, the black plating ensures that the washers do not corrode easily, thus maintaining their functionality over an extended period. Secondly, the black finish provides an aesthetically pleasing appearance. It gives the washer a sleek, uniform look, which can be particularly appealing in applications where the fasteners are visible, like in high - end furniture or decorative metalwork. Additionally, in some cases, the black plating can also enhance the surface hardness of the washer, improving its wear - resistance and overall durability.

Black - plated wave washers are commonly made from a variety of materials, with spring steel being a popular choice for general - purpose applications. Spring steel, such as 65Mn, offers excellent elastic properties, allowing the washer to withstand repeated compression and relaxation cycles without losing its spring force. In more demanding environments where corrosion resistance is crucial, stainless steel variants like 304 or 316 are used. These stainless - steel materials, combined with the black plating, provide enhanced protection against rust and chemical corrosion. In terms of specifications, these washers come in a wide range of sizes. They are available in both metric and imperial dimensions. Metric sizes typically range from M3 to M30 or even larger in some specialized applications. The inner diameter of the washer is designed to fit snugly around the bolt or shaft it is being used with, while the outer diameter and the height of the waves are proportionally sized to provide the right amount of spring force and load - bearing capacity. For example, a smaller M3 washer will have a more delicate wave structure compared to a larger M20 washer, which is designed to handle higher loads. In the imperial system, sizes range from #2 up to 1 - 1/2 inches, with similar considerations for dimensional compatibility.

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.
