Internal M7 Threaded Steel Balls Spherical Structure For Precision Instrument

The M7 threaded carbon steel ball is a carbon steel sphere with internal M7 threads. It integrates the flexible adaptability of a spherical structure and the secure fastening of M7 threaded connections, making it widely applicable in mechanical engineering, medium-heavy equipment assembly, precision instrument manufacturing, and DIY projects. It perfectly combines practicality and versatility to meet diverse application needs.

The product is mainly made of carbon steel, which has moderate hardness (HB 180-220), excellent toughness, and high cost-effectiveness. These properties make it suitable for medium mechanical load scenarios, such as connecting medium-sized components and providing structural support in industrial equipment.

1. Precision Threading: Internal M7 threads are machined using advanced CNC equipment, resulting in complete and accurate thread profiles with consistent pitch. This effectively prevents thread stripping or loosening during use, ensuring long-term stable performance.
2. Surface Treatment: Standard polishing creates a smooth finish, enhancing appearance and providing basic rust resistance. For harsher environments, optional treatments like zinc plating or black oxide coating are available to significantly improve corrosion resistance, especially in humid or corrosive conditions.
3. Detail Control: The manufacturing process ensures uniform machining marks and minimal assembly gaps, reflecting high-quality craftsmanship and guaranteeing consistent quality across batches.

1. Medium-Sized Rotating Components: In industrial machinery, M7 threaded carbon steel balls are used as connectors in medium-sized rotating mechanisms, such as shafts of medium-power motors and transmission linkages in material handling equipment. The spherical shape allows multi-angle adjustment, ensuring smooth operation under medium loads.
2. Structural Fasteners: They serve as important structural fasteners in equipment frames, heavy-duty brackets, and precision machine tool components, providing secure connections to maintain overall structural integrity.

1. Mechanical Prototyping: For DIY enthusiasts and engineering projects, M7 threaded carbon steel balls are essential components in building medium-sized mechanical prototypes and structural models. They are compatible with common M7 bolts and studs, facilitating easy assembly.
2. Custom Fabrication: In custom furniture making and industrial-style decorations, these balls act as both functional connectors and decorative elements, adding a unique touch to the design.

1. Instrument Brackets and Linkages: In precision instruments, M7 threaded carbon steel balls are used in brackets and linkage systems, providing stable positioning and flexible adjustment for sensitive components, ensuring accurate operation of the instruments.

1. Secure Thread Engagement: Precisely machined M7 threads ensure firm and reliable connection with external threads, reducing the risk of loosening caused by vibrations, suitable for applications requiring high stability.
2. Good Load-Bearing Capacity: Carbon steel's excellent toughness and wear resistance enable the balls to withstand medium loads and adapt to working environments with moderate friction and temperature variations, ensuring long service life.
3. Cost-Effective Solution: Using carbon steel as the base material offers an affordable option without compromising quality, ideal for mass production and project applications with budget considerations.
4. Wide Compatibility: The M7 thread size, though less common than smaller sizes, is widely used in specific industrial fields, making the balls compatible with various standard bolts, nuts, and threaded rods, simplifying assembly.
5. Customizable Options: We provide customization services for sphere diameter (common sizes range from 12mm-35mm), surface finish (polished, plated), and thread length to meet specific customer and application requirements.
