Product Details

Our Stainless Steel DIN 1587 Cap Nuts are engineered for a perfect blend of form and function.

• Dual-Function Design: Protection and Aesthetics:
  • Aesthetic Finish: The smooth, polished dome provides a decorative, high-end look, concealing the unsightly end of a bolt or stud. This creates a professional and finished appearance on any assembly.
  • Safety and Thread Protection: The cap encloses the threaded end, protecting it from environmental factors like dust, moisture, and physical impact. This extends the life of the fastener and the joint. It also creates a smooth, snag-free surface, preventing injury to people and damage to materials that might come into contact with it.
• Premium Stainless Steel Grades for Every Environment: We offer a range of stainless steel options to match the specific demands of your application:
  • SS201: A cost-effective stainless steel option suitable for indoor, dry, and decorative applications where high corrosion resistance is not the primary concern.
  • SS304 (A2): The most popular and versatile grade, offering excellent corrosion resistance for general-purpose indoor and outdoor use. It is the standard for most architectural, automotive, and machinery applications.
  • SS316 (A4): Known as “marine grade,” this steel contains molybdenum, providing superior resistance to chlorides, acids, and saltwater. It is essential for marine, coastal, chemical, and food-grade applications.
• DIN 1587 Standard for a Flawless Fit: Manufactured in strict compliance with the DIN 1587 standard, these nuts guarantee uniform dimensions, including the hex size, dome height, and thread profile. This ensures a consistent and professional fit every time.
