Thread lock adhesive refers to a product that is designed to secure and seal threaded fasteners, such as bolts, screws, and nuts. Thread lockers are used to prevent loosening or unintentional disassembly of threaded connections due to vibration, thermal expansion, or other external forces. They work by creating a strong bond between the threads of the fastener and the mating surface, effectively locking them in place.

There are different types and strengths of thread lockers available ranging from low-strength products that allow for easy disassembly with hand tools to high-strength ones that require the application of heat or special tools for removal. Thread lock adhesive typically comes in liquid form and is applied to the threaded portion of the fastener before assembly. Once the fastener is tightened, the thread locker cures to create a strong, durable bond that helps prevent loosening over time. Discover more in our in depth guide here.

What are the types of thread lock adhesive?

There are three main types of thread lockers

Low-strength thread lockers: These are typically used for applications where disassembly is required but resistance to vibration-induced loosening is still desired. They provide a medium-strength bond and can be removed using standard hand tools.
Medium-strength thread lockers: These thread lockers offer a slightly higher strength compared to the low-strength ones. They are suitable for applications that require a stronger bond but still need to be disassembled using hand tools.
High-strength thread lockers: These are designed for applications where maximum strength and resistance to vibration are required. They provide a secure, permanent bond that can withstand harsh conditions. Removing high-strength thread lockers often requires the application of heat or special tools.

What are the benefits of thread lock adhesives?

Prevention of loosening: The primary benefit of using thread lockers is the prevention of loosening of threaded fasteners. Thread lockers create a strong bond between the threads of the fastener and the mating surface, minimizing the effects of vibration, thermal expansion, and other external forces that can cause fasteners to come loose.
Increased reliability: By securing threaded connections, thread lockers enhance the reliability of assemblies and systems.
Vibration resistance: Thread lockers are particularly effective in applications exposed to vibrations.
Sealing and leakage prevention: Certain thread lockers, such as anaerobic pipe sealants, provide sealing properties.
Corrosion prevention: Thread lockers can also offer corrosion resistance.
Easy application: Thread lockers are typically easy to apply and require minimal preparation.
Versatility: Thread lockers can be used on a wide range of fasteners, including bolts, screws, studs, and nuts.
