Steelman Security Seal is the ideal way to protect yourself from both intentionally tampered fasteners and ones that have worked themselves loose due to vibration and normal operation. Mark a properly torqued fastener by creating either a seal along the base or a line that runs across the fastener head and onto the surrounding surface. If the fastener loosens, you will be able to tell with a quick glance that the seal is broken. The premixed formula is ready to go straight from the tube and dries quickly. Even when vehicle components are not spotlessly clean, the seal will have no problem sticking to both metal and plastic surfaces. To ensure that broken seals are easy to spot, the bright blue color stands out and will not fade in the sun or wash off in the rain. This pack includes ten 1-ounce tubes with extended plastic tips that allow for easy and precise application. STEELMAN is an industry leader in automotive and industrial specialty tools and equipment.
