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.

External Tooth Washer

 

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.

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.

Sealing Washers
Serrated Conical Washer

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.

FAQ

 

Q: How do sealing washers work?

A: Sealing washers typically feature a rubber or elastomeric sealing surface that compresses when installed, creating a tight seal between two mating surfaces. This compression is crucial for preventing fluid or gas escape, even under varying pressure and temperature conditions.

Q: What is the best material for sealing washers?

A: Rubber washers are appropriate for preventing leaks, protecting surfaces, and dampening vibrations in various applications. They also offer a tighter seal than metal washers due to their durability and flexibility.

Q: What is the difference between a star washer and a serrated washer?

A: Star washers have protruding teeth in a star pattern, providing better grip and resistance to rotation. Serrated washers have teeth along the inner circumference, offering friction to prevent loosening. Both serve similar purposes but differ in design.

Q: What materials are shoulder washers available in?

A: Shoulder washers are available in a variety of materials to suit different applications. Common materials include stainless steel, steel, brass, aluminium, and plastic. The choice of material depends on factors such as strength requirements, corrosion resistance, and environmental conditions.

Q: How can I determine the right size and type of shoulder washer for my project?

A: Determining the correct size and type of shoulder washer depends on factors like the material you’re fastening, load requirements, and environmental conditions.

Q: How do shoulder washers work?

A: A shoulder washer is used to insulate fasteners, wires or shafts from moisture and electricity. It looks like a typical flat washer on one end with an attached sleeve, or bushing, at the other end. The flange created by this design is inserted into a housing to provide a bearing surface for rotary applications.
