Brass SEMS Screws:
Brass SEMS screws are specialized fasteners that combine a screw with an integrated washer, designed for applications where a secure and reliable fastening solution is required. These screws are threaded and made from brass, offering excellent corrosion resistance and electrical conductivity. Below is a detailed overview of Brass SEMS screws, including their sizes, threads, usage, finish, and tolerances. We also manufacture and supply Copper SEMS screws, Stainless Steel SEMS screws and Bronze SEMS screws (Silicon Bronze Screws and Phosphor bronze Screws).
Sizes and Threads:
Brass SEMS screws are available in a variety of sizes and thread types to accommodate different applications. Common sizes range from #2 to 1/4 inch in diameter, with lengths varying from 1/4 inch to 2 inches or more. The threads are typically Unified National Coarse (UNC) or Unified National Fine (UNF), but custom threads can also be manufactured to meet specific requirements.
Usage:
Brass SEMS screws are widely used in industries such as electronics, automotive, and marine due to their corrosion resistance and conductivity. They are ideal for securing components in environments exposed to moisture or requiring electrical grounding. The integrated washer ensures a larger bearing surface, reducing the risk of damage to the material being fastened and providing a more secure hold.
Finish:
The finish on Brass SEMS screws is typically natural brass, which provides a visually appealing look while maintaining the material’s inherent properties. However, additional finishes such as nickel plating or passivation can be applied to enhance corrosion resistance or meet specific aesthetic requirements.
Tolerances:
Brass SEMS screws are manufactured to tight tolerances to ensure consistent performance and compatibility with standard nuts and threaded holes. The tolerances for thread pitch, diameter, and length are typically in accordance with industry standards such as ASME B18.6.3 or ISO 1207. Custom tolerances can also be achieved for specialized applications.
Advantages:
- Corrosion resistance due to brass material.
- Integrated washer eliminates the need for separate washers, saving time during assembly.
- Excellent electrical conductivity, making them suitable for grounding applications.
- Wide range of sizes and thread types available.
Applications:
- Electronics: Circuit boards, connectors, and grounding applications.
- Automotive: Securing components in engines, dashboards, and electrical systems.
- Marine: Fastening in saltwater environments due to corrosion resistance.
- General Manufacturing: Assembly of machinery and equipment requiring reliable fasteners.
In conclusion, Brass SEMS screws are versatile and reliable fasteners suitable for a wide range of applications. Their unique design, combined with the properties of brass, makes them an excellent choice for industries requiring corrosion resistance, electrical conductivity, and secure fastening. For specific sizing, threading, or finish requirements, consult with a manufacturer or supplier to ensure the best fit for your application.
