Product Description

Plastic Protective Cap Decoration Dustproof Round Head Hexagonal Nut Protective Cover DIN 1587





Cover nut "usually refers to the commonly used" cover nut "(also known as" cover nut "or" anti loosening nut ") in the mechanical field. It is a nut with a top closure cover, mainly used for fixing and protection. Here are its main functions:

1. Anti loosening effect
Cap nuts are often used in conjunction with bolts and screws to increase friction through their own structural design (such as nylon inserts, top pressure, etc.), preventing nut loosening due to vibration or external forces and ensuring the stability of the connection.

2. Dust and dirt prevention
The top sealed design can effectively prevent dust, moisture, or other impurities from entering the interior of the thread, protecting the connection from corrosion or blockage and extending its service life.

3. Safety protection
Cover the sharp part at the end of the bolt to prevent personnel or equipment from being scratched due to accidental contact and improve operational safety.

4. Aesthetics
The enclosed appearance makes the connection parts cleaner and is commonly used in occasions with higher appearance requirements, such as furniture and decorative engineering
