The Helical Coil Screw Thread Insert is installed into threaded holes within a water aftercooler cover to restore or reinforce fastening points. It ensures that the proper clamping force is maintained between connected components, supporting tight and stable assembly. It helps maintain correct sealing between mating surfaces, reducing the risk of coolant leakage during operation, and improves fastening reliability by providing consistent thread engagement under repeated tightening and loosening conditions.Attributes:• Supports tight sealing between connected cooling system parts.• Allows reuse of existing mounting holes.• Improves fastening stability during repeated maintenance.Applications: The Helical Coil Screw Thread Insert is located inside threaded mounting holes of a water aftercooler cover, where it restores and reinforces internal threads to ensure secure fastening, proper sealing, and stable attachment.
