FAQ

Q: Can a screw with minor paint loss keep working?
A: It may stay in service if threads are intact and no elongation occurs. Replacement is recommended during overhaul to avoid fatigue fracture.

Q: Should thread locker be applied during tightening?
A: Thread locker is recommended for heavily vibrated positions, and fasteners should be tightened diagonally to specified torque.

Q: Can a screw with slightly worn threads be reused repeatedly?
A: Repeated reuse is not advised. Worn threads lose preload capacity and tend to loosen under load.

Q: What failures may be caused by broken screws?
A: Component displacement, misaligned bearing housing and offset sprocket, followed by chain jumping and abnormal noise, even feeding shutdown in serious cases.
