Custom Precision Washers

Custom Washers

for Precision Applications

In precision assembly applications, washers are more than a basic ring. Etchit manufactures custom precision washers using photochemical etching, allowing us to produce flat, burr-free components with tight tolerances, complex geometries, and ultra-thin profiles that traditional stamping cannot achieve.

For industry applications where quality and precision matter, we can build washers engineered specifically for performance, stack-up control, conductivity, retention, or limited space constraints.

Our Capabilities

We offer full print-to-production custom manufactured washers for our customers, backed with comprehensive secondary services, including passivation, plating, and controlled packaging, to streamline project timelines.

In aerospace, medical, electronics, and high-reliability systems industries, washers are often critical functional components, not just commodity hardware. Let Etchit manufacture your custom washer geometries, optimized for application performance, manufacturability, and cost efficiency.

Our custom washers can include:

Tight concentricity between ID and OD
Micro-thin shim thicknesses
Anti-rotation tabs
Internal flats or keyways
Multiple inside diameters
Notches, slots, or retention features
Precision spacing geometries
Conductive or plated surfaces

We are committed to producing high quality washers and proudly maintain our ISO 9001:2015 Certification and are ITAR Registered, ensuring strict adherence to industry standards throughout each step of our process.

Material Selection

We commonly work with a variety of different materials to ensure the best conductivity, performance, and requirements for your custom washer including:

300 Series Stainless Steel
Copper
Beryllium Copper
Phosphor Bronze
Brass
Kovar
Nickel Alloys
Cold Rolled Steel

Don’t see your alloy listed? Contact us! It may still be a good fit for the photochemical milling process.

Thickness & Tolerance Capabilities

Material Thickness Range:

.0005” to .032” (depending on alloy)

Material type, thickness, and part geometry all impact tolerance capability. Our team can review your specific application and provide guidance on achievable tolerances to ensure performance and manufacturability.

Secondary Services

Your custom washer may require additional secondary services to meet your application and performance requirements.

We utilize trusted, third-party providers to produce high quality secondary services including:

Passivation
Plating
Forming

Our Photochemical Etching Washer Process

At Etchit, we use photochemical etching to create tight tolerance washers. Etched washers are:

Burr-free on both sides
Free of mechanical stress and distortion
Ideal for thin materials (.0005”–.032”)
Highly repeatable with excellent concentricity
Cost-effective for prototypes and short-to-medium production runs
Easily modified without hard tooling changes
Well-suited for complex geometric designs

Able to work with a variety of metal alloys and thickness, photochemical etching often produces cleaner results than traditional punch-and-die methods. This process also allows intricate features to be produced without material stress, rollover burrs, or tool wear distortion.
