Green Security Marker Markal Security Check in tube

Markal Security Check Paint Marker is an inspection paint used to visually detect whether torque fasteners have loosened due to vibration or been tampered with. This quick-drying, tamper-proof torque marker shows if a part has moved from its original position. Once dried, the Markal Security Check Paint Marker creates a seal for torque movement detection – the dry and brittle paint line will break, providing clear proof of loosening or tampering.

The marker is durable and suitable for use in extreme heat, helping to ensure workplace safety. Torque seal paints are widely used across many industries, including automotive, aviation and aerospace, railway, as well as amusement ride manufacturing and servicing. Markal Security Check Paint Marker supports quality control by enabling warranty management in the event of tampering.
