Stainless Steel Flat Washer
A stainless steel flat washer is a thin, disc-shaped component typically used in mechanical assemblies to distribute the load of a fastener, such as a bolt or screw. It is characterized by its material composition – various grades of stainless steel – and its flat, circular design.
Material:
Stainless steel alloys are utilized for their corrosion resistance, strength, and durability. Common grades include:
- 304 Stainless Steel: The most common grade, offering good corrosion resistance and formability. Suitable for general-purpose applications.
- 316 Stainless Steel: Contains molybdenum, enhancing corrosion resistance, particularly against chlorides. Ideal for marine environments or applications with harsh chemicals.
- 410 Stainless Steel: A martensitic grade, offering higher strength but lower corrosion resistance than 304 or 316. Often used in applications requiring higher mechanical properties.
- Other Grades: Depending on specific requirements, other grades like 316L (lower carbon content for improved weldability) or duplex stainless steels may be used.
Purpose & Function:
- Load Distribution: Spreads the load of the fastener over a larger area, reducing stress on the connected materials.
- Preventing Damage: Protects the surface of the connected materials from being damaged by the fastener.
- Corrosion Resistance: Stainless steel provides inherent resistance to rust and corrosion, extending the lifespan of the assembly.
- Tightening & Sealing: Can help maintain a consistent tightening force and prevent loosening due to vibration.
- Even Pressure Distribution: Ensures uniform pressure distribution, especially when dealing with softer materials.
Usage Scenarios:
- Construction: Used in structural connections, roofing, and siding.
- Automotive: Employed in various automotive assemblies, including engine components and body panels.
- Marine: Ideal for applications exposed to saltwater environments, such as boat building and dock construction.
- Plumbing: Used in plumbing systems to seal connections and prevent leaks.
- Electronics: Utilized in electronic enclosures and components requiring corrosion resistance.
- General Manufacturing: Found in a wide range of industrial applications.
Common Types:
- Standard Flat Washers: Basic, circular washers with a hole in the center.
- USS Flat Washers: A common standard with specific dimensional requirements.
- SAE Flat Washers: Another standard with slightly different dimensions than USS washers.
- Heavy Series Washers: Thicker washers designed for higher load applications.
- Fender Washers: Larger outer diameter for increased surface area and load distribution.
- Lock Washers (often used in conjunction): Split or serrated washers designed to prevent loosening. (e.g., split lock washers, tooth lock washers)
- Beveled Washers: Angled inner edge for use with countersunk fasteners.
- Nylon Washers: Used to reduce friction and noise. (Though not stainless steel, often used alongside stainless steel fasteners)
Stainless steel flat washers fall under several potential classifications based on the provided information. Here's a breakdown of relevant HS codes:
- 7318220000: This code covers screws, bolts, nuts, coach screws, screw hooks, rivets, cotters, cotter pins, washers (including spring washers) and similar articles, of iron or steel: Non-threaded articles: Other washers. Given that flat washers are generally non-threaded, this is a primary consideration. The tax rate details indicate a base tariff of 0.0%, an additional tariff of 25.0%, and a 30.0% additional tariff after April 2, 2025, with a 25% additional tariff for steel and aluminum products, resulting in a total tariff of 80.0%.
- 7318152091: This code covers screws, bolts, nuts, coach screws, screw hooks, rivets, cotters, cotter pins, washers (including spring washers) and similar articles, of iron or steel: Threaded articles: Other screws and bolts, whether or not with their nuts or washers: Bolts and bolts and their nuts or washers entered or exported in the same shipment Having shanks or threads with a diameter of <6 mm or more: Other: Other: Of stainless steel. While typically washers aren't threaded, if they are supplied with threaded bolts/nuts in the same shipment, this code becomes relevant. The tax rate details are identical to 7318220000, resulting in a total tariff of 80.0%.
- 8301600000: This code covers Parts. It is possible that stainless steel flat washers could be classified as parts, depending on their specific application. The tax rate details indicate a base tariff of 2.8%, an additional tariff of 7.5%, and a 30.0% additional tariff after April 2, 2025, resulting in a total tariff of 40.3%.
