Iron precision equipment type 0, type 3 + B-tight screw, trivalent chromate black.
FBP-0000EB-03
Iron precision machinery type 0, grade 3 + B-tight screw, trivalent chromate black.
Specifications: This product conforms to the Japan Camera Industry Association standard (JCIS10-70) and has a smaller screw head compared to JIS standard screws with a cross slot. It can be tightened while forming a female thread in the counterpart material, eliminating the need for female thread processing or nuts. The cross-section of the screw part is shaped like a rice ball (triangular), allowing for fastening with a smaller torque compared to tapping screws. It can be used with both metal plates and plastic materials. It enables standardization and integration of screws during assembly manufacturing. It is compliant with EU-RoHS regulations.

Applications/Examples of results
Steel is widely used as a steel material for screws due to its easy availability, strength, and toughness. Based on carbon steel, which primarily consists of iron (Fe) and carbon (C), alloy steels that have undergone heat treatment or have additives such as chromium and molybdenum are used according to applications such as shape, strength, and corrosion resistance. Trivalent chromate is a surface treatment that serves as an alternative to chromate plating, providing corrosion resistance equal to or greater than traditional chromate treatment without containing harmful hexavalent chromium. Additionally, it can control the decrease in corrosion resistance that occurs during heating, which is a drawback of chromate treatment. In recent years, there has been a growing global awareness of environmental measures, and many industries, including automotive and semiconductors, are considering alternative treatments to hexavalent chromium, with trivalent chromate being used as a substitute for chromate plating. On the other hand, compared to chromate treatment, managing the stirring state of the plating material, immersion time, temperature, and pH can be challenging, which may lead to uneven finishes in appearance and color. Furthermore, in general chromate treatment, the color may change as corrosion begins.
