Tension Indicating Bolts

Tension Indicating Bolts provide a clear indication of proper tension during installation, ensuring the structural integrity of connections. They are commonly used in steel construction, bridges, pressure vessels, wind turbines, and heavy machinery, where precise preload is essential to prevent joint failure. These bolts often incorporate Direct Tension Indicators (DTIs) (washers with compressible protrusions or visual media) that provide immediate feedback during tightening, making inspection and maintenance more efficient and reliable.
