DESCRIPTION
A captive isolator cap screw is a type of fastener used in truck components. Part number 3990876 specifically refers to the size and thread pattern of the screw. The term "captive" means that the screw is designed to be permanently attached to a specific component, preventing it from getting lost or misplaced during assembly or disassembly. The "isolator" part of the name refers to a rubber or plastic insert located between the screw and its mating surface. This insert helps dampen vibrations and reduce noise transmission between components, improving overall ride quality and comfort for drivers and passengers. The cap on top of the screw head provides a finished appearance while also protecting against dirt, debris, and moisture from entering the threads.
