"308型自攻螺套：规格、价格、安装指南与螺套底孔标准
The 308 Type Self-tapping Thread Insert is a new type of fastener designed to reinforce thread strength. As an enhanced version of the 307 Type, it offers increased functionality and easier installation. Widely utilized in various applications requiring reinforced thread strength and extended thread life, particularly in scenarios where enhancing thread strength, repairing damaged internal threads, or creating high-strength internal threads in softer materials is necessary, the 308 Type Self-tapping Thread Insert provides distinct advantages.
Main Functions:
1. Enhancing Parent Material Thread Strength: By embedding into softer materials like copper, aluminum alloys, magnesium-aluminum alloys, and plastics, the self-tapping thread insert creates high-strength internal threads, thus reinforcing the parent material's thread strength.
2. Extending Parent Material Thread Life: Significant extension of the parent material thread's lifespan is achieved through the use of self-tapping thread inserts.
3. Repairing Damaged Internal Threads: With the functionality of self-tapping threads, damaged internal threads can be directly repaired by screwing the self-tapping thread insert into the pre-drilled hole.
Product Features:
1. Self-tapping and Automatic Chip Removal Capability: The self-tapping thread insert features self-tapping and automatic chip removal capabilities, eliminating the need for pre-tapping the parent material, thus facilitating installation.
2. High Tensile Strength: With a large contact area with the finished product, the self-tapping thread insert can withstand significant tensile forces, ensuring connection stability.
3. Excellent Air Tightness and Vibration Resistance: Exceptional air tightness and vibration resistance prevent loosening and enhance connection strength with the parent material.
4. Easy and Quick Installation: The self-tapping thread insert offers simple and rapid installation, requiring only one assembly tool, resulting in low costs and virtually no defect rates.
5. Easy Assembly, High Strength Threads, and Vibration Resistance: As an enhanced version of the 307 Type, the 308 Type Self-tapping Thread Insert features easy assembly, high-strength threads, and vibration resistance, suitable for various applications requiring high-strength thread connections.
Specific Applications of the 308 Type Self-tapping Thread Insert:
1. Applications with Soft Materials: Materials such as copper, aluminum alloys, magnesium-aluminum alloys, and plastics have inherently low thread strength. The 308 Type Self-tapping Thread Insert significantly strengthens internal threads in such materials.
2. Applications Requiring Extended Thread Life: In components requiring frequent disassembly and assembly, the 308 Type Self-tapping Thread Insert effectively extends thread life, reducing failures caused by thread wear.
3. Repair of Damaged Internal Threads: For damaged internal threads, the 308 Type Self-tapping Thread Insert can be directly screwed into pre-drilled holes to create new high-strength internal threads, thus repairing damaged threads.
4. Connections Requiring High Strength: In applications requiring withstanding significant tensile forces and torque, such as mechanical equipment and automotive components, the 308 Type Self-tapping Thread Insert provides a reliable connection, preventing loosening and breakage.
5. Applications Requiring High Air Tightness and Vibration Resistance: With outstanding air tightness and vibration resistance, the 308 Type Self-tapping Thread Insert is suitable for sealed connections or applications in high-vibration environments, such as hydraulic systems, pneumatic systems, and engines.
6. Applications Requiring Quick Installation: Due to its easy and quick installation, the 308 Type Self-tapping Thread Insert is suitable for applications requiring rapid installation and disassembly, such as temporary fixing on production lines or repairs.
In summary, the 308 Type Self-tapping Thread Insert is an indispensable fastener in many industries due to its excellent performance and wide application range.
The self-tapping thread insert bottom hole standard is crucial for ensuring correct installation and connection of self-tapping thread inserts. Good bottom hole standards ensure the fit and stability between the self-tapping thread insert and the base material. When selecting and using self-tapping thread inserts, it is essential to follow the corresponding bottom hole standards to ensure connection reliability and safety.
The standard parameters for the bottom hole of the 308 Type Self-tapping Thread Insert are as follows:
Number Specifications Inner Diameter B Inner Thread Pitch Length L Outer Diameter A Outer Thread Pitch P Installation Bottom Hole Drill Depth
1 M3*0.5-L6-M5*0.6 M3 0.5 6 M5 0.6 4.7~4.8 8
2 M4*0.7-L8-M6.5*0.8 M4 0.7 8 M6.5 0.8 6.1~6.2 10
3 M5*0.8-L10-M8*1.0 M5 0.8 10 M8 1 7.6~7.7 13
4 M6*1.0-L12-M10*1.25 M6 1 12 M10 1.25 9.5~9.6 15
5 M8*1.25-L14-M12*1.5 M8 1.25 14 M12 1.5 11.3~11.5 17
6 M10*1.5-L18-M14*1.5 M10 1.5 18 M14 1.5 13.3~13.5 22
7 M12*1.75-L22-M16*1.75 M12 1.75 22 M16 1.75 15.2~15.4 26
8 M14*2.0-L24-M18*2.0 M14 2 24 M18 2 17.2~17.4 28
9 M16*2.0-L24-M20*2.0 M16 2 24 M20 2 19.2~19.4 28
Therefore, the 308 Type Self-tapping Thread Insert offers a variety of specifications covering different diameters, pitches, and lengths to meet the needs of different projects. Typically made from high-quality metals such as stainless steel or alloy steel, its material ensures durability and stability. Prices may vary depending on specifications, materials, and manufacturers. It is recommended to contact pre-sales customer service for detailed inquiries before purchasing.
During installation, it is essential to select an appropriate drill hole diameter based on the self-tapping thread insert's specifications to ensure it is fully embedded and securely connected to the base material. Avoid overloading and excessive tightening during use to prevent damage to the self-tapping thread insert or the connected components.
