ITW Dykem Cross-Check Tamper Proof Torque Seal
When you use Dymon® Cross-Check™ tamper proof torque marks, you'll immediately know if there's been some funny business going on with your assemblies, fasteners, nuts and bolts. This is true whether it's due to innocent aircraft vibration or something more sinister such as tampering.
Cross-Check is a highly visible fluorescent paste that dries to a hard brittle film that is easily broken if parts become loose or are tampered with. The product adheres well to metal and other materials and provides warranty protection against tampering.
* Drying time may vary depending on film thickness. Due to the nature of florescent pigment, colors are not lightfast, and eventually will fade away with UV exposure.
** Color might turn dark; however paint marks remains legible.
