Reasons and Solutions of Thread Assembly Deviation of Hardware Structure

How to solve misalignment after screw-tube assembly

In the assembly of hardware structural components, some customers have reported issues such as vertical deviation and lateral misalignment during product assembly, which actually stem from the inherent characteristics of threaded connections.

Threads are widely used in hardware component connections due to their advantage of easy rotation. However, threads feature a helical inclined structure, and clearance must be reserved for smooth threading, which makes it difficult to keep components aligned in the same direction during assembly. Additionally, surface coating treatments on components can alter the fit tolerance, further affecting the stability of the assembly position. If threads were not inclined, they would fail to achieve the tightening function, making inclination an inevitable attribute of threaded connections.

To address the aforementioned issues, Yusheng Hardware Technology leverages its deep technical expertise in the industry to propose three major solutions:

1. Ensure mating positions have chamfered holes to guide precise thread alignment.
2. Design reasonable fit clearance based on different surface treatment processes.
3. After assembling components to the specified depth, use adhesive to secure and maintain vertical alignment.

The above insights are shared with friends in the industry. Let’s work together to refine our products and specialize in excellence!
