Key Features
Integrated Flange
Built-in washer face increases bearing area, distributes clamping force, and protects surface finish. No loose washers needed.
Simplified Assembly
One part replaces screw + washer combination. Faster assembly, fewer parts to manage, reduced inventory.
Soft Material Protection
Larger flange diameter prevents pull-through in soft materials like plastics, composites, and thin sheet metal.
Clean Appearance
Smooth domed top with integrated flange provides professional look. Popular for visible consumer product fastening.
