What are Other Washers?
Other Washers are special washers designed to meet specific fastening, spacing, locking, sealing, positioning, insulation, or load distribution requirements. Unlike standard washers with fixed dimensions and common structures, these products may have special shapes, hole types, profiles, thicknesses, or functional structures. Custom washers are typically used when standard washers cannot meet the installation space, mechanical requirements, or design specifications of a particular component.

Types of Other Washers We Manufacture
Custom Flat Washers
In addition to standard round designs, we can produce washers with customized inner diameters, outer diameters, thicknesses, and profiles according to customer requirements.
Sealing Washers
Depending on the application, they can use metal, rubber, or composite structures. They are commonly used in automotive components, industrial equipment, hydraulic systems, and other assemblies requiring sealing around a fastener.
Lock Washers
Depending on the application, options can include tooth lock washers, internal tooth washers, external tooth washers, and other specialized locking designs.
Wave Washers
Wave washers have a wave-shaped profile that provides axial spring action when compressed. They can help compensate for dimensional variation and maintain contact pressure within an assembly.
Shoulder Washers
Shoulder washers have an extended shoulder around the inner hole and can be used for spacing, positioning, or electrical insulation. They are commonly used in electronics, electrical equipment, precision machinery, and applications where the fastener needs to be isolated from the surrounding component.
Special-Shaped Washers
For applications requiring a specific installation profile, Zeyao can manufacture square, rectangular, tab, oversized, and other special-shaped washers. These products are normally produced according to customer drawings or samples to ensure the dimensions and geometry match the final assembly.
Other Washer Materials
Material selection directly affects washer strength, corrosion resistance, weight, machinability, and cost. Zeyao provides different material options according to product requirements.

Applications of Other Washers
Sealing Washers
Sealing washers can be used for a variety of purposes, including:
Automobile industry
Sealing washers play a vital role in automotive systems by preventing fluid leakage and ensuring safety and performance across engine, brake, fuel, and transmission components.
Aerospace
Sealing washers and O-rings are indispensable in aerospace applications, safeguarding hydraulic, fuel, and pneumatic systems to uphold flight precision, safety, and operational reliability.
Plumbing and HVAC
Sealing washers and O-rings are essential components in plumbing and HVAC systems, ensuring watertight seals and efficient operation for fluid flow and climate control, respectively.
Construction industry
Rubber sealing washers are used in roofing and cladding systems to provide weatherproof seals around fasteners, preventing water ingress and maintaining building integrity.
Electrical Installations
Nylon washers and rubber grommets are employed in electrical enclosures and conduit fittings to seal out moisture and contaminants, ensuring electrical safety and reliability.


Serrated Conical Washer
Serrated conical washer can be used for a variety of purposes, including:
Anti-Vibration Applications
One of the most common uses of serrated washers is to prevent vibrations in assemblies. The serrations on the washer’s surface provide additional resistance against loosening caused by vibrational forces. This makes them particularly useful in machinery, automotive, and aerospace industries, where stability and integrity are crucial.
Electrical Connections
Serrated washer are often utilized in electrical connections to maintain proper grounding and enhance conductivity. By ensuring a secure connection, they minimize the risk of electrical faults or failures due to loose fasteners. Their serrated design aids in maintaining a consistent electrical contact over time, even in dynamic or high-vibration environments.
Locking Mechanism
The serrated teeth on the washer’s surface create a locking effect when combined with a compatible fastener, such as a bolt or a nut. This locking mechanism helps prevent the fastener from loosening under various conditions, including cyclic loads, thermal expansion, or vibrations. Serrated washer are frequently employed in heavy machinery, construction, and infrastructure projects.
Shoulder Washer
Shoulder washers can be used for a variety of purposes, including:
Electronics
Ensure stable connections in electronic devices by using shoulder washers between circuit boards and securing screws or bolts.
Automotive Sector
Improve stability and strength in various automotive components by incorporating shoulder washers.
Construction Projects
Enhance stability and security in construction projects by utilising shoulder washers for connecting different building materials.
Machinery
Shoulder washers are a trusted choice in machinery, ensuring even load distribution and safeguarding equipment against wear and tear.
