Washers for Strong & Reliable Load Distribution
Washers are essential fastening components that distribute load, prevent damage, and improve stability in bolted assemblies. Horizon Inc. offers a full range of washers — flat washers, lock / spring washers, structural washers, and specialty types — in stainless steel, carbon steel, and other materials. Whether for construction, industrial machinery, electronics, or fabrication, we deliver precision washers that last.
What is a Washer and Why it Matters?
A washer is a thin plate (usually disk-shaped) with a hole, placed under a nut or bolt to spread the tightening force and reduce surface stress. In high-performance joints, hardened washers help prevent brinelling and maintain preload.
Washers also serve as spacers, locking devices, or vibration dampeners depending on the type (flat, spring, Belleville, etc.).
Materials & Finishes
- Stainless steel (A2/304, A4/316) for corrosion resistance
- Carbon steel (plain, zinc plated, black oxide) for cost-effectiveness
- Brass, copper, nylon / plastic variants for electrical insulation or non-metallic use
Finishes: zinc plated, galvanized, black oxide, passivation, etc.
Types of Washers
Here’s an overview of the different types of washers we offer, designed for specific purposes across multiple industries:
Plain Washers
Standard washers providing a smooth surface between the fastener and the surface, helping to evenly distribute the load and prevent surface damage.
Spring Washers
Designed to provide resistance against loosening caused by vibration, ensuring a secure connection for critical applications that experience constant movement.
Conical Washers
Also known as belleville washers, these provide additional load-bearing capacity by compressing under load, making them ideal for high-pressure applications.
Star Washers
These washers have teeth that dig into the surface, providing a better grip and preventing the fastener from turning or loosening under vibration.
Push Lock Washers
Ideal for quick assembly, these washers are used for fastening without the need for a nut, providing a locking feature that prevents disassembly.
Multitooth Washers
With multiple teeth around the edge, these washers provide a higher degree of grip and resistance to rotational loosening, perfect for demanding applications.
Wave Washers
These washers are used in applications where spring-like action is required, typically in situations where flexibility and load compression are necessary.
Shim Washers
Used for precise thickness adjustments, shim washers are perfect for fine-tuning alignment and ensuring uniform pressure in mechanical assemblies.
Taper Washers
Used in applications that require the washer to fit into a tapered or angled surface, these washers maintain proper alignment under pressure.
Cup Washers
With a cup-like shape, these washers are commonly used in securing fasteners against vibrations and offering added protection to the surface.
Nylon Washers
These non-metallic washers are ideal for insulating, preventing galvanic corrosion, and providing vibration damping properties in delicate assemblies.
How to Choose the Right Washer
- Match inner hole to bolt size (e.g. M8 bolt → M8 washer)
- Choose outer diameter / thickness for load distribution
- Select material & finish per environment (corrosion, temperature)
- For high vibration, use lock washers or spring types
- Use specialty washers (Belleville, fender) when needed for spacing or load control
Applications and Use Cases of Washers
