Frequently Asked Questions
How are freight car bolts installed?
Freight car bolts are installed using a torque wrench to ensure that they are tightened to the correct torque specification.
How to avoid failures while using freight car bolts?
Ensure that bolts are installed and maintained correctly.
What is the importance of proper torque when installing freight car bolts?
Proper torque is critical when installing freight car bolts. If a bolt is under-torqued, it may not provide sufficient clamping force, leading to loosening or failure. If a bolt is over-torqued, it can strip the threads or damage the bolt that further leads to failure. Proper torque ensures that the bolt is tightened to the correct specification, providing the necessary clamping force without causing damage.
What is the importance of thread lubrication when installing freight car bolts?
Thread lubrication ensures that the bolt can be tightened to the correct torque specification without damaging the threads. It also prevents corrosion and seizure of the bolt over time.
