Markal Security Check+ High Temp.

Safety marking pens contain highly visible paint, which is applied across the screw head and the adjacent surface. Once the marking is in place, it can later be checked to see whether the screw has moved or loosened: a break or shift in the paint indicates a change. The pens are suitable for monitoring fastenings in various machines, electrical equipment, and other structures. They allow for a quick visual inspection without separate measuring devices.
