Applying Your Threadlocker – It Doesn’t Have to Be Tricky

Applying Your Threadlocker – It Doesn’t Have to Be Tricky

Threadlockers. We’ve taken a swing at answering some of your most asked questions around them, now it’s time to take a look over the woes some of us have when it comes to their application. Before we begin, it is worth setting the scene around their general purpose.

 

Thread-locking fluid is used when you’re looking to prevent the tendency of fastener assemblies, such as screws and bolts, from becoming loose; as a bonus, they also prevent corrosion!

 

For these reasons, thread-locking fluid becomes an indispensable tool in your kit whenever you’re installing an assembly that will not undergo routine maintenance for prolonged periods of time as well as undergoing shock, vibration, and temperature fluctuations as part of its usual operation.

 

Right, that’s enough of a preface – let’s move on to the practical knowledge you can take home - or to work – to avoid pitfalls that can cause issues for you and your assembly over time should you not apply your threadlocker well.

 

1)    Keep That Fastener Clean!

You can’t expect your thread-locking fluid to do all the work. Getting the most out of your product means putting in some preparation beforehand; clean out threads contaminated with oil, dust, and grease, remembering to thoroughly dry them before application. Note that this advice applies to both male and female threads.

 

2)    Stronger Isn’t Always Better

You’ll have a range of strength options available to you when it comes to thread-locking fluid. It can be easy to succumb to the ‘stronger is better’ mentality, but you’d be doing your assembly a disservice in the long run. As a convenient example, let’s take the threadlockers available here at Invertech Canada to demonstrate what we mean; we stock the following ranges:

  • Low Strength (Purple) – surface removable on bolt and screw diameters <0.25”
  • Medium Strength (Blue) – surface removable on bolt and screw diameters >0.25”
  • High Strength (Red) – high strength and temperature resistance that form the strongest bond. Require heat for disassembly.

3)    Frugality Is Your friend

Drawing a parallel to No. 2 on the list, more does not equate to better when it comes down to applying your thread-locking liquid. We recommend the first few threads be given attention, the liquid will take care of the remaining threads once the fastener is tightened. Apply too much and you run the risk of excess locking fluid spilling out into areas it doesn’t belong.

 

4)    Curing Starts with You! No Need to Dawdle.

It may feel counterintuitive, but thread-locking fluids cure when there is an absence of oxygen, making them anaerobic; much unlike humans, relegated to our aerobic ways. A successful cure can only take place when you tighten the fastener – this helps keep the air out. Waiting around for the fluid to dry from atmospheric exposure can lead to contamination, which we already touched upon with point no. 1! We do, however, advise that curing thoroughly occur before putting your assembly to work.

 

Speaking of which…

We’re pretty proud of the range of threadlockers we house here at Invertech Canada, with fixture times ranging from 4 – 30 minutes, we’re sure you can find a product (we’re also happy to help) to meet the bonding requirements you need when securing your nuts and bolts. Put our Superior Adhesive Technologies® (SAT) brand of threadlockers to the test with any competitive brand, we’re confident we’ll match or surpass them!


Informative! Awesome threadlocker tips.
