Twin-lock is a unique structural rivet. The double sealing head that forms after application makes the fastening extremely intact and reliable. The particular bulb-shaped head of the stem deforms creating a counter-head that prevents its extraction, possible only with the appropriate equipment. Twin-lock is ideal for application on all types of metals, plastics and composite materials and offers high tensile strength and ample clamping thickness, and its locking mechanism protects the application from corrosion.
- Bulb open counterhead
- Water tightness between the body and mandrel
