Nylon rimless plugs are designed to suit screw sizes ranging from 2.6 to 12.0mm and feature a grey nylon finish. Suitable for medium to heavy-duty applications, larger sizes are ideal for use with coach screws. These plugs are commonly used when fixing satellite dishes and can be inserted to depths below the base material. The two-way expansion allows for use in close-to-edge applications, while sprung spin fins provide a two-way lock, preventing spinning and loosening in overhead applications.
