FAQ
Q: What should be considered for export packaging?
A: Due to its long shaft, sturdy packaging that prevents bending is essential, such as using strapping to secure it or custom-made long wooden crates with dividers. The markings must clearly indicate the thread specifications and length at both ends.
Q: How to ensure its quality?
A: The key is to require the supplier to provide mechanical performance test reports for the plain shaft section. For important projects, physical tensile testing can be requested to verify its overall load-bearing capacity.
Q: Do the threads at both ends have to be the same?
A: Not necessarily. The standard model has equal diameters and the same thread direction (e.g., both ends are M16 right-hand threads). Customization is available for different specifications or thread directions at both ends to achieve specific connection or locking functions.
