Q1. What is the thread locking process for screws?
The so-called “Thread locking process for screws” refers to the addition of anaerobic glue, nylon glue and sealant that provides thread locking function to “general screws” with the feature of using general screws without special design or process.
Q2. How does the thread locking process for screws work?
All screw fasteners contain the “Torque moment of possible loosening”. Simply put, a loosening strength is generated at the same time when tightening the screw into a work piece, according to “action and equal and opposite reaction” in the laws of physics. The screw itself is not expensive, yet the time consumed to assemble parts with screws can possibly take more than half of the total production hours. More hours will be consumed if single or several screws are loose and entail rework. If such loosening interferes with normal production, the cost from rework, repair, damaged creditability and even litigation in regard to product liability is beyond imagination. Therefore, the thread locking process on general screws serves as insurance that the screws will be kept at a fixed position and designed torque right from beginning, which is the safest and reliable approach, as well as the most cost-saving approach.
Q3. Which industry needs the thread locking process for screws?
Any industry that uses screws to secure objects (or for positioning adjustment) and may face loss due to loosening screws, needs such process. In particular, the labor-orientated products at lower-level in the past have now moved overseas and the remaining products need to compete with manufacturers in the USA, Japan and Europe; thus the importance of the “tiny screw” that ensures 100% performance of the products should not to be overlooked.
Q4. How many types of thread locking process for screws are available?
A：Fixed (chemical tightening): This method applies anaerobic glue onto the threads of general screws for achieving oxygen deficiency when tightening the screws, which further secures the screws.
B：Repetitive (physical tightening): This method applies nylon glue or sealant onto the threads of general screws for achieving the effect of friction when tightening the screws, which prevents the screws from loosening.
