Key Properties of LOCTITE 262
- Color: Red
- Strength: Medium/High
- Temperature Range: -65°F to 300°F (-54°C to 150°C)
- Disassembly: Requires heat and mechanical force or chemicals (Tameson)
Here’s a comparison table illustrating some key attributes:
| Property | LOCTITE 262 |
|---|---|
| Color | Red |
| Strength | Medium/High |
| Temperature Range | -65°F to 300°F (-54°C to 150°C) |
| Disassembly Requirements | Heat, Torque, Chemicals |
To enhance LOCTITE 262’s performance, especially on oily surfaces, using a primer such as 7471 is recommended. This combination ensures optimal adhesion even on “critical” engine parts like cam sprockets and tensioners.

Factors Impacting Effectiveness
Consideration of Thread Size
When selecting between LOCTITE 242 and LOCTITE 262, one crucial factor to consider is the size of the threads. The effectiveness of a threadlocker can be significantly influenced by the dimensions of the threaded components.
High-strength threadlockers, such as LOCTITE 262, may present difficulties during removal when applied to small threads. Conversely, using a low-strength threadlocker like LOCTITE 242 on larger threads may reduce its effectiveness. To ensure optimal performance, it is essential to match the threadlocker strength to the thread size.
Thread Size Recommendations
Below is a table summarizing recommended thread sizes for LOCTITE 242 and LOCTITE 262:
| Threadlocker | Strength | Recommended Thread Size |
|---|---|---|
| LOCTITE 242 | Medium | 1/4″ – 3/4″ (6mm – 20mm) |
| LOCTITE 262 | High | Larger than 3/4″ (20mm) |
Considerations for Different Applications
Choosing the right threadlocker based on thread size also depends on the specific application and conditions. For instances involving vibration and torque, medium or high-strength threadlockers are recommended to provide the highest resistance to vibration, shock, and torque as a permanent solution (Henkel Adhesive Technologies).
- Vibration and Torque: LOCTITE 262 is ideal for applications exposed to high vibration and torque, as it provides maximum resistance.
- Ease of Removal: If future disassembly is a consideration, LOCTITE 242 is preferred for smaller threads due to its medium strength.
Breakaway Torque
To further understand the effectiveness, it’s useful to refer to the breakaway torque, which indicates the strength of the threadlocker alone without additional tightening torque to the parts.

Maintenance and Reliability
Maintaining Torque Over Time
When comparing LOCTITE 242 vs. 262, one critical factor to consider is how well these threadlockers maintain torque over time. Both LOCTITE products are designed to ensure the reliability of threaded assemblies, but their specific characteristics influence their performance in different applications.
LOCTITE threadlockers are known for their ability to prevent threaded assembly failure by maintaining impressive bond strengths and clamp load retention during vibrational cycles (LOCTITE). The bond strength of LOCTITE 242 (medium strength) and LOCTITE 262 (medium/high strength) provides resistance to torque and vibration, securing the fasteners in place.
| Feature | LOCTITE 242 | LOCTITE 262 |
|---|---|---|
| Color | Blue | Red |
| Strength | Medium | Medium/High |
| Viscosity | Medium | Medium/High |
| Torque Resistance | Moderate | High |
Medium or high-strength threadlockers like LOCTITE are recommended for applications involving high risks due to vibration and torque, offering the utmost resistance (Henkel Adhesive Technologies). LOCTITE 242 provides a reliable bond for most general-purpose applications, whereas LOCTITE 262 is more suited for heavy-duty applications where higher torque retention is required.
Proper application is also key to maintaining the effectiveness of these threadlockers. Ensuring that the threads are clean and dry before applying the product, and allowing adequate curing time, will enhance the reliability of the assembly.
LOCTITE threadlockers allow for the easy disassembly of fastener assemblies when needed, using appropriate tools and techniques. This ensures that maintenance and adjustments can be performed without compromising the integrity of the fasteners.
