ISO 7380 Button Head Socket Screws

FULLERKREG supplies ISO 7380 button head socket screws in both standard round head (ISO 7380-1) and flanged head (ISO 7380-2) variants, across all major material grades and surface treatments. The low-profile domed head provides a clean, attractive appearance with a wide bearing surface — ideal for applications where a standard socket cap head is too tall. Select your series below:
