Product Information
Full details
This guide is for anyone using the K2 PROLOK Threadlocker to secure threaded fasteners in automotive, industrial, or other applications. The key benefit is its high-strength formula that prevents loosening due to vibration and shock. A key consideration is that the adhesive requires metal-to-metal contact to cure properly.

FAQs
What is the shelf life of K2 PROLOK?
The shelf life is typically 12-24 months if stored in a cool, dry place with the cap tightly closed.
Can I use K2 PROLOK on plastic parts?
No, K2 PROLOK is designed for use with metal fasteners only.
How do I remove cured K2 PROLOK?
Cured K2 PROLOK can be removed using hand tools. Applying heat can help soften the adhesive. Use a thread restorer or cleaner to remove any remaining threadlocker from the fastener and the receiving threads.
Can I reuse a fastener after using K2 PROLOK?
Yes, but it is recommended to clean the threads and reapply K2 PROLOK for optimal performance.
What is the temperature range of K2 PROLOK?
K2 PROLOK is effective in temperatures ranging from -50°C to 150°C.
How much torque can K2 PROLOK withstand?
The breakaway torque on an M10 bolt is 20-43 N/m.
What is the cure time for K2 PROLOK?
It begins to cure in less than 15 minutes, reaches 60% strength after 1 hour, and full strength after 24 hours.
Troubleshooting
Fastener is loose after application.
Ensure the surfaces were clean, sufficient threadlocker was applied, and the full curing time of 24 hours has passed. Also, verify that the correct torque was applied during assembly.
Difficulty removing a fastener.
Apply localized heat to the fastener (e.g., with a heat gun) to soften the adhesive, then use appropriate tools to remove it. Be careful not to damage the surrounding components.
Pros and Cons
Pros
- Provides a strong, reliable bond for threaded fasteners.
- Resists loosening caused by vibration and shock, enhancing safety and reliability.
- Effective across a wide temperature range, suitable for diverse environments.
- Can be used on slightly oily surfaces, simplifying application.
- Allows for disassembly with standard tools if needed.
Cons
- Requires metal-to-metal contact for proper curing.
- Curing time is required before the full strength is achieved (24 hours).
- May require more force to remove fasteners compared to lower-strength threadlockers.
- Not suitable for use with non-metal fasteners.
Setup, Compatibility & Care
- Surface Preparation: Ensure the metal surfaces are clean and free of loose debris. While K2 PROLOK can tolerate slight oil, cleaning the surfaces enhances adhesion.
- Application: Apply the threadlocker to the threads of the fastener. Use enough to fully cover the threads.
- Assembly: Assemble the components and tighten the fastener to the manufacturer's recommended torque.
- Curing: Allow the threadlocker to cure. It begins to cure in about 15 minutes, reaches 60% strength in 1 hour and full strength in 24 hours.
- Compatibility: K2 PROLOK is compatible with all metal fasteners and is suitable for threads up to M25. It is not designed for use with non-metal fasteners.
- Care: Store the tube in a cool, dry place. Replace the cap immediately after use to prevent the product from drying out.
