Loctite 243 Threadlocker

Loctite 243: Reliable Medium Strength
Threadlocker for Secure Fastening

Loctite 243 is a versatile, medium-strength threadlocker designed to prevent nuts, bolts, and other threaded fasteners from loosening due to vibrations or shock. This high-quality adhesive is ideal for applications requiring a secure bond that can still be removed with standard tools, making it a popular choice for maintenance professionals, engineers, and anyone needing dependable threadlocking in various environments.

Key Features and Benefits

• Medium-Strength Formula: Loctite 243 provides a reliable bond strong enough to keep fasteners secure under heavy vibrations but can still be disassembled with standard hand tools, allowing for easy maintenance and repairs.
• Enhanced Performance on Oiled Surfaces: Unlike some threadlockers, Loctite 243 can be applied effectively on surfaces with light oil contamination, such as those commonly found in industrial or mechanical settings, ensuring an optimal bond without extensive pre-cleaning.
• Resistant to Shock and Vibration: Designed to withstand intense vibration and shock, Loctite 243 is ideal for equipment, machinery, and automotive applications where fasteners are exposed to continuous movement or environmental stress.
• Prevents Rust and Corrosion: Loctite 243 forms a protective seal around fasteners, helping prevent rust and corrosion over time. This benefit prolongs the lifespan of your equipment and improves reliability in challenging environments.
• Wide Temperature Range: Loctite 243 operates effectively in temperatures ranging from -55°C to 180°C, making it suitable for applications in both extreme heat and cold, including automotive engines and industrial machinery.

Common Applications

• Automotive Repairs: Ideal for securing bolts, nuts, and studs in vehicles, Loctite 243 ensures they stay tight under vibration from engines or road conditions.
• Industrial Machinery Maintenance: Suitable for keeping fasteners secure in industrial equipment subjected to heavy use, reducing the need for frequent tightening and maintenance.
• Electrical and Mechanical Equipment: Ensures reliable fastening in machinery, tools, and electronic equipment exposed to movement or temperature fluctuations.
• Home Repairs and DIY Projects: Perfect for projects around the house where a dependable yet removable fastening is required, such as on garden equipment, bicycles, or hobby components.
