ForgeFix Rimless Wall Plugs can be inserted to depths below the surface of the base material. Their sprung anti-spin fins provide a two-way lock, preventing spinning and loosening from overhead applications. Due to this precise two-way expansion, the plugs are suitable for close to edge applications. Made from 100% nylon, these plugs are ideal for both lightweight and medium-duty fixing applications, such as wall lights, shelving, and cupboards. They are often used for satellite dish installation and are suitable for most types of threaded screws including multi-purpose, general purpose, and coach screws. Size: M12 x 60mm. Supplied in a bag of 25. Not suitable for machine screw threads.
