Learn how to choose the right washers for assemblies exposed to constant vibration. Horizon Inc explains washer types and their roles in keeping fastened joints secure.
How to Select Washers for Vibration-Prone Applications
In many industries — from machine tools, and automotive assemblies to renewable energy projects — constant vibration is a reality. Without proper fastening hardware, vibration can cause joints to loosen, parts to shift, and structures to fail prematurely. And one of the simplest, yet most critical components to counter this problem is the washer.
At Horizon Inc, we supply a variety of washers specially designed for vibration-prone applications. In this post, we’ll guide you on how to select the right washer type to secure your fastened joints against dynamic loads.
📌 Why Washers Matter in Vibration-Prone Installations
✔ Prevent fastener loosening under repeated vibration
✔ Distribute load and protect against material deformation
✔ Compensate for thermal expansion and movement
✔ Seal joints from dust, moisture, or liquids (in case of bonded washers)
✔ Extend the lifespan of assemblies by preventing hardware loss or damage
📌 Types of Washers for Vibration Resistance
🔹 Nord-Lock Wedge-Locking Washers
One of the most advanced vibration-resistant solutions. Nord-Lock washers use a pair of cam-faced washers that interlock under tension. The cams have a greater angle than the thread pitch, ensuring that any loosening movement is countered by the wedge effect of the cams, effectively locking the fastener in place even under extreme vibration and dynamic loads. Widely used in critical applications like wind turbines, heavy machinery, automotive suspension, railways, and structural steel joints.
🔹 Spring Washers (Split Lock Washers)
Provide constant tension against the fastener, reducing loosening in dynamic conditions. Common in machine tool assemblies and transport equipment.
🔹 Star Washers (Internal & External Tooth)
Create additional friction between the fastener and surface, ideal for electrical panels and assemblies prone to moderate vibration.
🔹 Conical (Belleville) Washers
Suitable for high-load and limited-space applications where joint flexibility and preload retention are essential.
🔹 Wave Washers
Provide light tension and absorb minor shocks — used in delicate assemblies like electronics and instrument housings.
🔹 EPDM Bonded Washers
Used with self-drilling screws in roofing, solar structures, and outdoor telecom cabinets — seal and cushion joints while absorbing vibration.
🔹 Nylon/Insulating Washers
Reduce vibration transmission and electrically isolate fasteners in sensitive electronic or electrical assemblies.
📌 Factors to Consider When Selecting a Washer
✔ Load and Vibration Intensity:
Heavier vibrations require springs or Belleville washers. Wedge locking washers like Nord-Lock provide efficient bolt locking.
✔ Material Compatibility:
Use stainless steel or plated washers in corrosive or outdoor environments.
✔ Joint Type:
For sealed joints, bonded washers work best; for electrical applications, star washers are preferred.
✔ Space Constraints:
Wave and Belleville washers suit limited-clearance situations.
✔ Fastener Type:
Always match washer size and material to the fastener being used.
