Conical Lock Washer Performance
Elastic Preload
The conical profile generates elastic restoring force when compressed, providing controlled preload within the bolted joint.
Load Retention
The spring action compensates for minor joint movement and compression changes, helping maintain more consistent clamping force.
Vibration Resistance
Elastic deflection helps accommodate dynamic movement in bolted assemblies and reduces the effect of preload loss caused by joint movement.
Controlled Deflection
The washer provides a defined load-deflection response, allowing the required spring load and working deflection to be considered during joint design.
Thermal Compensation
The elastic structure can accommodate dimensional changes caused by thermal expansion and contraction within the specified working range.
Stable Spring Characteristics
Controlled material properties, heat treatment and conical forming help maintain consistent load and deflection characteristics across production batches.
Conical Washers are produced from spring-capable materials selected according to the required load, deflection and service environment. Material and surface treatment are controlled to maintain the washer's spring characteristics while providing the required level of corrosion protection.
- Spring Steel
Used for applications requiring defined elastic deformation and stable spring load under compression.
- Alloy Steel
Suitable for applications requiring higher strength and controlled spring performance under demanding mechanical loads.
- Stainless Steel
Selected for assemblies exposed to moisture, corrosive environments or where higher corrosion resistance is required.
- Surface Treatment
Available finishes include phosphating, zinc-aluminum coating and other specified treatments. The selected finish can be matched to the required corrosion resistance, operating environment and customer specifications.
Conical Lock Washer Applications
Conical Lock Washers are used in bolted assemblies where elastic spring action is required to accommodate changes in joint compression and maintain the specified clamping condition.
- Industrial Machinery
Used in mechanical equipment and machine assemblies where bolted joints are exposed to operating loads and movement.
- Automotive Components
Applied to selected bolted connections requiring controlled spring characteristics and dimensional consistency.
- Industrial Equipment
Suitable for equipment assemblies where changes in load, temperature or joint compression need to be accommodated within the washer's working range.
- Mechanical Structures
Applicable to structural and mechanical assemblies requiring a defined spring load and controlled deflection from the washer.

FAQ
How is a conical washer installed?
It is installed under the bolt head or nut, with the washer positioned according to the specified assembly direction. The contact surfaces should be clean and properly aligned before tightening.
Can these washers be used in high-temperature assemblies?
The suitability depends on the material, heat treatment and actual operating temperature. For elevated-temperature applications, material selection should be confirmed based on the working conditions.
Can I order samples before placing a bulk order?
Yes. Samples can be arranged for dimensional verification and assembly testing before proceeding with larger production quantities.
