DIN961 EN ISO8676 Full/Half Thread Carbon Steel Hexagon Head Bolts With Fine Pitch Thread Grade 4.8,6.8,8.8 Plain

Advantages:

1. Fine pitch bolts are commonly used in situations requiring high-strength connections. The fine pitch design enables the bolt to disperse the force over a smaller contact area, thereby increasing the strength per unit area. This makes the bolt capable of withstanding higher stress and having higher bearing capacity when subjected to the same load.
2. The design of fine pitch threads allows for a tighter fit between the bolt and nut, reducing clearances and looseness during the assembly process, improving assembly precision, and ensuring the stability and reliability of the connection.
3. The fine pitch design reduces the clearance in the tight fit, enhances sealing capability, and is suitable for applications requiring sealing.
4. The hexagonal head design offers superior grip and torque transmission efficiency, making it easier to manipulate the bolt with tools like wrenches or screwdrivers during installation and disassembly processes.

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.
