About the Thread Lock

Orange Thread Lock – High Strength with Easier Removal

The orange formula (PTK-1579) provides high-strength retention for fasteners exposed to heat, such as applications around motors and engines. It offers a stronger hold than light- or medium-strength options while remaining easier to remove than the red maximum-strength formula. Some applications may require heat to loosen the fastener, making orange a useful choice when additional holding power is needed without committing to the most permanent connection.
