Overview

Dykem® Cross Check™ Torque Seal Tamper-Proof Indicator Paste, part number 83317, is a viscous, oil-based yellow paste applied as a thin bead across a fastener and adjoining surface. Once cured, the mark will crack or break if vibratory loosening or tampering occurs, providing immediate visual evidence. The formulation adheres well to metal and other substrates, is visible in ambient light and fluoresces under UV, and is used for inspection, quality control and warranty protection in high-vibration assemblies.
