DIN961 EN ISO8676 Zinc Plated Hexagon Head Bolts Grade 4.8 / 6.8 / 8.8 With Fine Pitch Thread

DIN961 EN ISO8676 Carbon Steel Hexagon Head Bolts With Fine Pitch Thread Grade4.8,6.8,8.8 Color-Plated Zinc

Advantages:

1. High Strength: Due to the fine pitch design, the bolt can disperse the force over a smaller contact area, thus increasing the strength per unit area.
2. High Precision: The fine pitch thread allows for a tighter fit between the bolt and nut, providing higher assembly precision.
3. Excellent Sealing Performance: The close fit of the fine pitch thread reduces gaps, resulting in superior sealing capabilities, especially suitable for sealing applications.
4. Easy Assembly: The hexagon head design makes the bolt easier to manipulate with tools such as wrenches or screwdrivers during assembly and disassembly.

Characteristics:

1. Fine Pitch Design: As mentioned, the fine pitch thread is the primary characteristic of this bolt, providing the aforementioned advantages.
2. Hexagon Head: The hexagon head design ensures stability during operation and easy rotation with tools.
3. Good Interchangeability: Following unified international standards, these bolts have good interchangeability, making it convenient for users to select and replace them.

Applications:

1. High-Precision Equipment: Due to the high precision and excellent sealing performance of fine pitch bolts, they are often used in equipment requiring precise connections, such as precision instruments and aerospace equipment.
2. Vibration Environments: Fine pitch bolts' high strength and superior locking performance make them suitable for applications subject to vibration and impact, such as automobiles, motorcycles, and ships.
3. Sealing Applications: The tight fit of fine pitch bolts makes them particularly suitable for sealing applications, such as pipelines and fuel tanks.

In summary, Hexagon head bolts with fine pitch thread, with their high strength, high precision, excellent sealing performance, and ease of assembly, have found widespread applications in various scenarios requiring precise connections and sealing.
