Vibra-Tite Viz-Torque® 202

Viz-Torque 202 Tamper Detection Marker is an inspection paste used to visually detect torque movement due to vibratory loosening or tampering of fittings, assemblies, nuts, bolts and studs. This quick-drying tamper proof torque marker identifies whether a part has been moved from its original position. Once dried in place, Viz-Torque 202 Tamper Detection Marker creates a seal for torque movement detection, which allows the dry and brittle material stripe to break, providing proof of fastener tampering or loosening. Viz-Torque 202 has good adhesion to most metals when applied to a clean, dry surface and is available in a selection of highly visible colors.

Why use Viz-Torque?

Once dried in place, Viz-Torque is resistant to environmental elements, but brittle and fragile enough to consistently break in the case of tampering or loss of torque. Early detection of a loose fastener helps prevent collateral damage and limits time and cost associated with repairs.
