Fine thread bolts, also known as micro screws, are characterized by their very small size, typically smaller than M2.6. They are often referred to as miniature screws, precision screws, or ultra-small screws, and are crucial for assembling small and precision devices such as mobile phones, watches, and medical equipment. The use of fine thread bolts allows for more compact device designs.
However, due to their small size, fine thread bolts require careful handling. Precision, dexterity, and concentration are necessary to avoid damage to parts and equipment during installation.
Fine thread bolts are utilized in various fields where small size and precision are paramount. Here are some examples:
In the electronics industry, fine thread bolts secure circuit boards and components within compact and complex device structures, such as smartphones and cameras.
For medical devices like endoscopes, artificial joints, and cardiac pacemakers, fine thread bolts are essential for ensuring precision assembly, reliable operation, and accurate imaging.
Optical instruments, including microscopes and telescopes, rely on fine thread bolts for the precise placement and adjustment of lenses and mirrors.
Fine thread bolts are key in assembling clock mechanisms, ensuring accurate timekeeping by securing the arrangement of parts and gears.
Fine thread bolts adhere to the basic principles of screw threading but are specifically designed for small size and fine detail. They consist of a rod with a spiral groove that connects or secures parts by rotating into female threads. Their threads are finely detailed, often measured in metric millimeters, requiring precise installation work.
The head of a fine thread bolt varies in shape, allowing rotation with appropriate tools like screwdrivers. Common head shapes include Phillips and hexagonal.
Fine thread bolts come in various sizes from No. 01 to No. 3, with No. 00 being smaller than No. 0. The numbers indicate the size and height of the head, with countersunk and pan heads being common shapes. Material options include iron, carbon steel, stainless steel, and titanium, with options for special materials like resin or brass. Some bolts feature nylon on the threaded part to create a locking effect through friction.
The current standard for fine thread bolts is that from the Camera and Imaging Equipment Industry Association. Its specifications continue to influence the design and use of fine thread bolts in precision equipment.
