DIN 985 Steel Cap Nuts Hex Base Dome Top Bolts For Protection Aesthetics
Cap nuts are fasteners that integrate protective functionality and decorative appeal. Featuring an integrated "hexagonal base + dome-shaped top" design, they provide comprehensive coverage and protection for bolt ends.
- The hexagonal base works with standard tools (wrenches, sockets), enabling quick and easy installation
- The dome-shaped top fully covers exposed bolt threads, hiding burrs and preventing impact damage
- Protects against dust and moisture to prevent thread rust
The smooth dome surface gives assembly areas a neat, polished look. Perfect for situations where exposed bolts need both function and beauty, eliminating the roughness of visible threads.
- Base Material: High-strength carbon steel (stainless steel available as custom option)
- Surface Treatment: Standard galvanization (nickel plating, Dacromet, etc. available as options) for enhanced corrosion resistance
- Compatibility: Internal threads match standard bolts (GB, ISO, etc.) with customizable sizes (M4 to M24)
Protect surface bolts and reduce thread damage during maintenance operations
Enhance the appearance of exposed connections on tables, chairs, and cabinets
Shield chassis and exterior bolts from mud, dirt, and rust
Provide polished appearance for exposed fasteners on railings and display racks
Cap nuts combine protection (corrosion resistance, impact protection), aesthetics (thread hiding), and ease of use (hex-based installation) — making them the top choice for functional decorative fasteners.
