Unmatched Reliability for Your Fasteners: Introducing Loctite 243 Medium Strength Threadlocker

At 3FPARTS.COM, we understand the critical need for secure and reliable fastening solutions. That's why we bring you the Loctite 243 Medium Strength Threadlocking Adhesive (50 ml), the iconic blue threadlocker designed to prevent loosening and leakage from vibration in a wide range of applications.

Loctite 243 is a revolutionary general-purpose anaerobic adhesive that creates a medium-strength bond, perfect for metal nuts and bolts from M6 to M20. Its advanced formulation ensures exceptional performance even on oil-coated, "as-received" fasteners, eliminating the need for pre-cleaning in most cases. This versatile liquid threadlocker works reliably on all metals, including passive substrates like stainless steel, aluminum, and plated surfaces, offering unparalleled flexibility for your projects.

How it Works: This innovative adhesive fills all microscopic gaps between mating threads. Upon curing, it transforms into a tough, thermoset polymer, effectively sealing the threads and reinforcing the entire joint against the detrimental effects of shock and vibration. This ensures your assemblies remain intact, preventing costly downtime and maintenance issues.

Key Features & Benefits You'll Value:

• Medium Strength – Removable with Hand Tools: Enjoy the perfect balance of security and serviceability. Loctite 243 provides reliable retention to prevent accidental loosening, yet allows for easy disassembly using standard hand tools for maintenance or repair, unlike permanent threadlockers.
• Prevents Loosening and Leakage from Vibration: Specifically engineered to combat the challenges of dynamic environments, Loctite 243 secures fasteners against back-out caused by constant vibration and shock, while also forming a reliable seal against leaks.
• Works on All Metals, Including Passive Substrates: Whether you're dealing with active metals like brass and steel or passive materials such as stainless steel, aluminum, and plated surfaces, Loctite 243 delivers consistent, high-performance bonding without the need for a primer.
• Suitable for Oil-Coated Fasteners: A significant advantage for industrial and automotive applications, this adhesive can be applied directly to most oil-coated, "as-received" fasteners, streamlining your workflow and saving valuable time.
• Fast Fixture Times: Get your projects moving swiftly with impressive fixture times, allowing components to be handled sooner:
  • Brass: 5 minutes
  • Steel: 10 minutes
  • Stainless Steel: 10 minutes
