Product Description
DIN 985 Steel Cap Nuts Hex Base Dome Top Bolts For Protection Aesthetics
Product Overview

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.

Core Design & Functions
Structural Advantages
  • 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
Aesthetics & Protection Unity

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.

Material & Performance
  • 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)
Typical Applications
Mechanical Equipment

Protect surface bolts and reduce thread damage during maintenance operations

Furniture Assembly

Enhance the appearance of exposed connections on tables, chairs, and cabinets

Automotive/Motorcycle

Shield chassis and exterior bolts from mud, dirt, and rust

Decorative Projects

Provide polished appearance for exposed fasteners on railings and display racks

Advantage Summary

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.
