| Blue (LOCTITE 243) | Medium | Removable with hand tools | General purpose, primerless |
| Red (LOCTITE 263, 271, 268) | High | Requires heat to remove | Permanent, high-temperature applications |
| Green (LOCTITE 290) | Wicking | Post-installation application | Preassembled fasteners, set screws |
- Purple (LOCTITE 222): A low-strength threadlocker ideal for small fasteners that may need manual adjustments.
- Blue (LOCTITE 243): Medium-strength, designed for general-purpose applications and can be removed with common tools (loctite 221 vs. 222).
- Red (LOCTITE 263, 271, 268): High-strength, meant for permanent bonding, requiring heat (up to 500°F) for removal. Suitable for high-risk vibration or shock scenarios (loctite 263 vs. 272).
- Green (LOCTITE 290): Wicking-grade, perfect for post-installation applications like electrical connectors and set screws.
Appropriate Applications
The appropriate choice of Loctite threadlocker largely depends on the requirements of the assembly, such as the need for disassembly, the operating environment, and the size of the fasteners.
- Low-Strength (Purple): Use LOCTITE 222 for small fasteners or screws that require delicate handling.
- Medium-Strength (Blue): LOCTITE 243 is ideal for general assembly tasks. Its medium strength allows removability with standard tools, making it versatile for most needs (loctite 242 vs. 243).
- High-Strength (Red): For permanent bonding, especially in high-stress environments subject to vibration or high temperatures, products like LOCTITE 263 or LOCTITE 271 are recommended (loctite 262 vs. 263 vs. 271).
- Wicking-Grade (Green): LOCTITE 290 is best for preassembled fasteners where disassembly is not feasible. It seeps into the threads and provides a strong hold after installation.
