FAQ
When should this fastening solution be considered?
It is suitable for assemblies where components need to remain securely connected under vibration, movement, or repeated mechanical loads.
Can it be used instead of a solid dowel pin?
It depends on the application requirements. This type of pin is mainly designed for retention and fastening, while solid dowel pins are typically selected when precise alignment and positioning are the primary requirements.
What factors should be evaluated before selecting a pin?
Engineers should consider the application environment, load conditions, hole specifications, assembly requirements, and whether the connection needs permanent or removable fastening.
