DESCRIPTION
The screw cap provides a protective closure for fastener heads or threaded ports, guarding against dust, moisture, and accidental contact that could compromise threads or contamination sensitive interfaces. This small component contributes to longer service life for screws and threaded fittings by reducing corrosion and debris ingress. Selecting the correct cap involves matching inner diameter and external geometry to the mating component, as well as considering material compatibility with surrounding fluids and environmental exposure. Routine checks ensure the cap remains seated and intact, preventing contamination pathways and protecting top‑side hardware during maintenance or operation. Source One Parts Center.
