Bolt Lock High Strength for Large-Sized Threads (Red, 50g) is a threadlocker adhesive designed for securing large-diameter bolts, studs, and fasteners. The red formula provides a strong, permanent bond, preventing loosening from vibration, shock, or high stress. It is ideal for heavy-duty applications in industries such as automotive, construction, and machinery, where large fasteners are subject to significant forces and need a secure, long-lasting hold. The 50g size offers enough adhesive for multiple large-scale applications. Due to its high-strength nature, removal typically requires heat or specialized tools.
