Conical Spring Washers (Belleville Load Washers)

Conical spring washers DIN 6796, also known as Belleville washers or conical washers, are designed to maintain tension in bolted joints where vibration, thermal expansion or settling could otherwise reduce clamp load over time. Their cone-shaped profile creates a spring effect under compression, helping to maintain preload and improve joint reliability in demanding applications.

Fixabolt supplies stainless steel conical washers for trade and industrial use across fabrication, machinery, maintenance, plant equipment, structural assemblies and general engineering applications.

Why Choose Conical Spring Washers from Fixabolt

DIN 6796 conical spring washers are designed specifically for high-load bolted connections where maintaining clamp force is important.

Key benefits include:

  • Helps reduce loosening caused by vibration and movement
  • Maintains preload in bolted joints
  • Suitable for high-load applications
  • Compact design with high load capacity
  • Stainless steel construction for corrosion resistance
  • Available in common metric sizes to suit standard fasteners

Our stainless steel conical washers are suited to both indoor and outdoor environments where corrosion resistance and long-term reliability are required.

What Conical Washers Are Used For

Belleville washers are commonly used where a bolted joint is exposed to vibration, fluctuating temperatures or heavy static loads.

Typical applications include:

  • Structural steel assemblies
  • Mechanical plant and machinery
  • Pipe supports and flange connections
  • HVAC installations
  • Pumps and motors
  • Rail and transport equipment
  • Maintenance and repair work
  • Outdoor environments when stainless steel is required

Unlike plain washers, conical spring washers apply an axial spring force when compressed. This helps compensate for small movements, relaxation or settlement within the joint.
