Ensuring the verticality (perpendicular alignment) of long screws is critical in the following situations:
Precision Assembly
When the screw passes through multiple aligned components or holes, especially in mechanical or structural assemblies, poor verticality can lead to misalignment, stress concentration, or even assembly failure.
Structural Stability
In construction or steel structures, if a long screw is not vertically aligned, it may not bear the load evenly, affecting the overall stability and safety of the connection.
Aesthetic Requirements
In visible or decorative installations (such as façade systems or exposed panels), tilted screws may look unprofessional or result in uneven surfaces.
Automated Installation
For automatic screwdriving or robotic assembly, vertical deviation can lead to jamming, improper seating, or rejection by quality control.
Thread Engagement Accuracy
When the screw needs to be inserted into a tapped hole or nut, vertical misalignment can cause cross-threading or poor engagement.
