How Do Different LOCTITE® Strengths Compare and Which One Is Right for Your Application?
LOCTITE® Threadlockers
When it comes to preventing threaded fasteners from loosening under vibration, heat, pressure, or repeated use, LOCTITE® threadlockers remain one of the most trusted solutions in manufacturing and industrial assembly. But, choosing the right product can make a major difference in assembly consistency, production efficiency, and long-term reliability.
The Coating House (TCH) is the only Henkel LOCTITE® Authorized Pre-Applied Service Center on the East Coast. Our team combines decades of specialized coating fastener expertise with the ability to source, coat, and deliver ready-to-install fasteners tailored to customer applications.
Whether customers need low, medium, or high-strength LOCTITE products, TCH will partner with you to ensure you select the right coating for your specific operating conditions, reducing assembly errors, improving vibration resistance, and streamlining production.
What Does “Strength” Mean in LOCTITE® Threadlockers?
When it comes to threadlockers, “strength” is defined as the amount of force required to remove a fastener after the adhesive has cured. This removal force is commonly called breakaway torque.
Simply put:
- Higher-strength products require greater torque for removal
- Medium-strength products balance holding power with maintainability
- Lower-strength products allow easier disassembly
Choosing the correct LOCTITE® strength depends on several application factors, including:
- Vibration exposure
- Fastener size
- Maintenance requirements
- Temperature conditions
- Material compatibility
- Chemical exposure
Because every application is different, our knowledgeable team works directly with you to evaluate your performance requirements and recommend the appropriate LOCTITE® adhesive solution for long-term reliability.
Which LOCTITE® Strength Fastener Is Right for My Application?
LOCTITE® threadlockers fall into three primary categories: low, medium, and high strength. Use the comparison chart below to determine which level of LOCTITE® strength fastener you need based on your application.
| LOCTITE® Strength Level | Best For | Common Applications | LOCTITE® Color | LOCTITE® Products Available from The Coating House |
| Low Strength |
Smaller fasteners and assemblies requiring frequent adjustment and maintenance
|
|
Purple | LOCTITE® DRI 203 ECO™ |
| Medium Strength | Versatile fastening where vibration resistance and future serviceability are both important |
|
Blue | LOCTITE® DRI 202 ECO™ |
| High Strength |
Critical fastening applications where maximum resistance to loosening is required |
|
Red | LOCTITE® DRI 201 ECO™ |
TCH supports customers in various highly regulated industries including aerospace, automotive, electronics, emergency services, government and military, industrial, and medical devices, providing ideal fasteners for unique applications.
What Is the Benefit of LOCTITE® Pre-Applied Fasteners?
You are probably familiar with liquid LOCTITE® products applied manually during assembly. However, pre-applied LOCTITE® coatings offer significant advantages in production environments.
LOCTITE® pre-applied coatings are machine-applied to fasteners before shipment, creating ready-to-use “PAAC’D®” (Pre-Applied Adhesive-Coated) fasteners that eliminate the need for manual adhesive application during assembly. Unlike field-applied threadlockers, pre-applied coatings provide uniform coverage and controlled application every time. TCH specializes in pre-applied fasteners and our proprietary PAAC’D® process improves:
- Assembly consistency
- Production speed
- Torque repeatability
- Vibration resistance
- Operator efficiency
TCH is more than just a standard fastener supplier. Our fastener capabilities simplify your procurement process by providing coated, PACC’D® fasteners from a single trusted supplier. We also provide comprehensive fastener product services including:
- Product consulting
- Lot traceability
- Kitting services
- Plating services
- Engineering collaboration
- Documentation support

To ensure quality and compliance at each step of the process, The Coating House proudly maintains our:
- AS9100 certification
- ISO 9001 certification
- ITAR registration
- NIST 800-171 Rev 2 compliance
Because our team understands both fastening performance and coating processes, we can help you determine whether low, medium, or high-strength LOCTITE® products are best for specific applications.
