Our stretch bolts are manufactured from specially selected and heat-treated steel, allowing them to stretch in a controlled manner without losing their mechanical properties. This makes them ideally suited for applications where temperature changes or vibrations are normal - as well as where standard bolts would fail.

 

Thanks to their resilient properties, stretch bolts contribute to:

• Capturing thermal expansion
• Prevention of loose connections under cyclic loading
• A stable and safe assembly over a long period of time

 

Typical applications

Stretch bolts from Archey are used in industries where reliability under dynamic conditions is essential:

• Heat exchangers (heat exchangers) in power plants and process industry
• Turbines and boilers with high thermal loads
• Bridges, pylons and towers subject to movement and temperature variation
• Aerospace and automotive applications with varying forces and vibrations
• Industrial plants with cyclic loads and structural stresses

 

Technical specifications

• Material: High-strength steel, optionally in heat-resistant or creep-resistant alloys
• Tensile behavior:Designed to stretch within controlled tolerances, without loss of clamping force
• Heat resistance: Resistant to high temperatures in thermally stressed installations
• Application:Suitable for flange connections, heat exchangers and other critical structures
• Machining: Available according to drawing, including threaded machining, head shape and size as required
