Колпачок Jinggong 7x8.5 M4 черный

The hexagonal nut protective cap by Jinggong is designed to provide reliable coverage for fasteners. It effectively protects the threads and nut faces from dust, debris, and moisture, preventing corrosion and premature wear.

Made from high-quality polyethylene (PE) plastic, this cover offers excellent resistance to chemical exposure and mechanical damage. The material ensures durability and shape retention even under heavy use.

In addition to its protective functions, these caps serve as a decorative cover, hiding rough fastener edges and giving the finished product a cleaner, more professional appearance. They are easy to install and fit securely.
