Why PAAC’D® Outshines Traditional Nylok Patch Fasteners
Manual application of threadlocking materials and the use of nylon patch fasteners like Nylok have long been prone to inconsistency and assembly delays. In contrast, PAAC’D® (Pre-Applied Adhesive Coated) fasteners come pre-coated using Henkel® Loctite® Dri-Loc® or Dri-Seal®, eliminating human error, mess, and variable coverage.
How It Works
PAAC’D® Fasteners
- Dry-to-the-touch coating with microencapsulated chemistry.
- Activates during installation to form a secure bond or seal.
- Effective across temperatures up to 400°F.
- Shelf life up to 4 years when stored properly.
Nylok Patch Fasteners
- Uses a nylon wedge pre-applied to threads.
- Provides self-locking capability through friction.
- Typically reusable and resistant up to 250°F.
- Long-lasting when stored correctly.
Benefits Comparison
| Feature/System | PAAC’D® (Adhesive-Coated) | Nylok Patch (Nylon-Coated) |
|---|---|---|
| Application Precision | Factory-controlled, consistent | Variable due to patch placement |
| Assembly Speed | Instant use, color-coded for efficiency | Pre-applied but can require rework |
| Cleanliness & Waste | No mess, no bottles, no disposal issues | Nylon debris can shed during use |
| Temperature Range | Up to 400°F | –70°F to 250°F |
| Shelf Life | Up to 4 years | Indefinite with ideal storage |
| Locking Mechanism | Chemical bond/seal | Mechanical wedge |
PAAC’D® Fasteners Use Cases & Real-World Savings
In aerospace, automotive, and military manufacturing, consistency and speed matter. PAAC’D® fasteners eliminate the variability of field-applied threadlocker or nylon patches – cutting labor, reducing errors, and ensuring traceability.
“Quality control is at the top of the list, because we remove the potential for human error.” ~Harley Kata, General Manager.
AS9100D & ITAR Certification & Compliance
PAAC’D® fasteners are produced in an AS9100-certified, ITAR-registered, and Henkel® Authorized Pre-Applied Service Center. This level of certification supports mission-critical industries with demanding regulatory requirements.
Is It Right for You?
Opt for PAAC’D® if you:
- Want a standardized application and assembly.
- Require clean, fast, reliable part handling.
- Need QC traceability and longer shelf life.
Use a Nylok patch if you:
- Prefer a mechanical locking method.
- Need reusability for specific torque profiles.
- Operate within moderate temperature ranges.
