301 Stainless Steel Belleville Washers

Belleville washers are unique, conical shaped washers recommended for use in problematic or critical bolting applications. Their conical shape affords a high spring rate over a short deflection to retain the proper bolting stress in a variety of conditions. The loss of a sound bolted connection can lead to fugitive emissions, cause equipment failure, or catastrophic events. Belleville washers can eliminate bolted joint failures due to a variety of causes:

• High-temperature bolt yield
• Differential thermal expansion
• Packing or gasket relaxation or creep
• Vibration
• Thermal cycling
• High cycle applications

301 Stainless Steel Belleville Washers are a common, economical solution to maintain the integrity of bolted connections in a variety of applications.
