This is a special captive-style nut designed specifically for securing floor screws in Land Rover Defender and Discovery 1 vehicles. It functions as a threaded receiver for floor panel fixing screws, holding them in position against the chassis or floor structure without requiring access from beneath. Using the correct nut type is important as incorrect replacements can strip threads, cause floor panels to work loose, or create rattles under load. Key Features Specialist nut profile matched to Land Rover floor screw fixing system Designed for direct replacement without modification to surrounding floor structure Meets OEM fitment specification for Defender and Discovery 1 floor assemblies Floor fixings should be inspected for corrosion during any floor panel removal; replace in sets where multiple nuts show thread wear Vehicle Fitment Fits Discovery 1 (1989–1998), Defender 90, 110, and 130 (1983–2006), and Defender 90, 110, and 130 (2007 onwards), all in the floor screws fixings application.
