Frequently Asked Questions
-
Q: What is the intended application of this nylon insert?
A: It is designed for use in rail fastening systems to secure bolts and prevent loosening under dynamic loads. Typical applications include mainline railways, metros, and industrial tracks. -
Q: Can the insert be used with bolts of different thread pitches?
A: This specific model has a 1.5mm thread pitch. For other pitches, we can produce custom inserts upon request. -
Q: Is the 1000-cycle fatigue test conducted under simulated real-world conditions?
A: Yes, the test simulates the repeated loading and unloading forces experienced by rail fasteners during train passage. The insert maintained structural integrity throughout the test. -
Q: What is the typical lead time for bulk orders?
A: For standard sizes, lead time is 15–20 days after order confirmation. Custom orders may require additional time depending on complexity. -
Q: Do you provide samples for quality evaluation?
A: Yes, we offer free samples for freight collect. Please contact our sales team to arrange. -
