Low-profile design with small interference area: 10 mm outer diameter and 3 mm thickness minimize obstruction when mounted on plates or rigs. Strong locking and easy installation: 3.0 mm side hex groove provides reinforced grip and secure locking; can be tightened from the bottom with a screwdriver for convenient, tool-friendly installation. Fits most quick-release plates and camera cages: 4.4 mm screw-shank diameter is compatible with the typical waist-round holes used in fast-release plates, camera cages and similar accessories.
