Loctite 577 is a high-strength, general-purpose threadlocker designed to prevent loosening of threaded fasteners due to vibration, shock, and temperature extremes. It is an anaerobic adhesive that cures in the absence of air, forming a strong bond between metal surfaces.
Loctite 577 is an anaerobic adhesive, meaning it cures in the absence of air. When applied to the threads of a fastener, it fills the gaps between the metal surfaces. As the adhesive cures, it forms a tough, rigid bond that prevents the fastener from loosening.
Loctite 577 is suitable for a wide range of applications, including:

Story 1: In a manufacturing plant, bolts on a critical assembly kept loosening due to vibration, resulting in frequent downtime for repairs. The use of Loctite 577 on the bolts solved the problem, eliminating downtime and saving the company thousands of dollars in maintenance costs.
Lesson learned: Loctite 577 can effectively prevent fastener loosening and reduce maintenance expenses.
Story 2: A construction worker was having trouble installing bolts in an overhead application. The bolts kept falling out due to gravity. Loctite 577 was applied to the bolts, enabling them to be securely installed and preventing them from loosening.
Lesson learned: Loctite 577 is a versatile solution for difficult-to-reach or overhead applications.
Story 3: An electronics manufacturer was experiencing issues with circuit boards loosening due to thermal expansion and contraction. By applying Loctite 577 to the fasteners, the issue was resolved, improving product reliability and reducing warranty claims.
Lesson learned: Loctite 577 is an ideal choice for applications where thermal cycling can cause fastener loosening.
