The importance of thread cleaning
There are many factors that determine the quality of a bolted connection. One of the most important factors is friction, which can be influenced in many ways. Overcoming the friction caused by external factors like corrosion, old grease or concrete residue is one of the most time-consuming parts of (de)assembling bolted connections. The amount of friction has great impact on the amount of torque that is needed to achieve the desired bolt load. Professional thread cleaning leads to a more predictable and lower coefficient of friction over the entire length of the thread. That is why cleaning nuts and bolts before re-using them is an important step in any bolting process.
The advantages of using BoltClean thread cleaners
In general, we can diversify four methods for cleaning threads on nuts and bolts.
- Recutting threads
- Manual brushing
We performed laboratory tests to determine the effects of each cleaning method. The outcomes showed that machine-brushing has got many advantages over other methods.
