Direct Tension Indicator Washer

Direct Tension indicators(DTI Washers), also known as Auto Torque Indicators, are single-use mechanical load cells designed to indicate the magnitude of preload in the assembly, It shows if the bolt is properly tensioned, it is very useful while tensioning High Strength Structural bolts. Direct tension indicator washers (DTIs) are innovative fasteners designed to provide a visual indication of proper bolt tension. These washers feature protrusions that flatten as the bolt is tightened to the specified tension, ensuring accurate and reliable tensioning in structural and high-stress applications. Ideal for use in construction, bridges, and heavy machinery, DTIs enhance safety and performance by guaranteeing correct tension in critical assemblies. Made from high-quality materials, these washers offer excellent durability and resistance to wear and environmental conditions.
