Chrome Button Head Screws

The DIN 7991 Hex Socket Button Head Screw (Functionally identical to ISO 7380) is a German-engineered low-profile fastener characterized by its semi-spherical head with deep internal hex drive. Designed for space-critical and high-shear applications, it delivers exceptional clamping force with ultra-low head height (30-40% reduction vs. standard cap screws).
