It’s an easy mistake to make: when applying threadlocker, many DIYers and even industrial users follow the “more is better” logic. You want to make absolutely sure the screw won’t move, so you drench the threads. The result? A sticky,gooey overflow that creates a massive mess, interferes with adjacent moving parts, and may even lead to the threadlocker failing to cure properly in the first place.

This is a classic threadlocker mistake. Threadlocking adhesives like the Incure Re-Lok™ series are highly effective, but only when used precisely. We’ll show you why excess adhesive is a problem and how to master the “less is more” application technique.

Why Excess Threadlocker Is a Major Problem

Applying too much threadlocker creates two primary issues that hurt your assembly and your component:

1. External Non-Cure (The Gooey Mess)

Threadlockers are anaerobic—they cure only in the absence of oxygen (when sealed between the threads) and in the presence of metal ions.

• The Problem: Any excess adhesive that squeezes out of the assembly and remains exposed to the air will never fully cure. It will remain a liquid or a tacky, messy goo indefinitely, attracting dirt, dust, and metal shavings.
  
• The Risk: This gunk can interfere with nearby components, clog lubrication channels, or simply make the assembly look unprofessional and difficult to handle.

2. Internal Over-Cure Interference

While rare, applying a vast excess can sometimes displace air unevenly, leading to an overly thick layer of cured material deep in the joint.

• The Problem: The volume of cured material may exert unnecessary stress on the assembly or, in worst-case scenarios, push out into areas where it can interfere with internal moving parts (like shafts, bearings, or internal mechanisms).

The Incure Re-Lok™ Application Masterclass: Precision, Not Volume

The goal is simple: apply just enough product to fill the void between the engaged threads. You do not need to cover every thread before assembly.

The Standard Application Technique (For Bolts up to 3/4″ / 20mm)

For most general-purpose applications using products like Incure Re-Lok™ B43 Blue (Standard Duty) or B22 Purple (Light Duty), follow this simple guide:

1. Clean First: As always, ensure both the screw and the mating threads are thoroughly cleaned and degreased.
   
2. Apply a Small Bead: Apply a continuous, thin bead of threadlocker only to the threads that will be fully engagedwhen tightened. A good rule of thumb is to apply the bead around the leading thread and the third thread up from the end of the bolt.
   
3. Assemble: As you thread the bolt into the hole or nut, the turning action will force the liquid to spread along the entire engaged thread length, ensuring full coverage without excess.
   
4. Wipe the Ooze: If a tiny bit of material squeezes out, wipe it off immediately with a clean cloth before it can cure.

Deep Hole Application (Blind Holes)

For blind holes (holes that don’t go all the way through), the air trapped at the bottom can be compressed, preventing the threadlocker from reaching the threads.

• The Technique: Apply a few drops of threadlocker down into the female (internal) threads at the bottom of the hole, before inserting the bolt. As the bolt is driven in, it will push the adhesive up and along the threads, ensuring complete coverage and a secure anaerobic seal.

Recommendation for Precision: Incure Re-Lok™ B90 Wicking Grade (Green)

If you are working with small components, pre-assembled parts, or applications where precision and cleanliness are paramount, consider the Incure Re-Lok™ B90 Green Threadlocking Adhesive (Wicking Grade):

By adopting these precision application methods, especially using the right tool like a controlled-flow bottle or the wicking-grade Incure Re-Lok™ B90, you can eliminate the problem of messy overflow and achieve a perfectly secured,clean assembly every time.
