Product Description

A Comprehensive Overview of Machine Rice Screws for Precision Engineering and Mechanical Assembly.

Machine mounted screws, renowned as set screws, stop screws, or headless screws, are innovative fasteners with a sleek, headless design. They are engineered for the axial positioning and secure fixation of mechanical components, expertly transmitting loads through end compression while effectively preventing loosening. Discover below their essential features and diverse classifications:

------

1. Basic Definition

Machine rice screws derive their name from their diminutive size, resembling rice grains, and typically feature a headless structure. Precision tools like hexagonal or slotted screws are employed for tightening, ensuring secure and reliable application.
Their multifaceted functions include:

Fixed Positioning: These screws, once threaded into a component's screw hole, press firmly against the surface of another component to restrain any relative displacement, ensuring stability.

Anti-Loosening Effect: Certain models incorporate stop washers or specialized thread designs, significantly enhancing their resistance to vibrations.

Structural Features

1. End Type:

Cone End: Featuring a sharp tip, it is ideal for compression positioning in materials with low strength, such as plastics.

Flat End/Concave End: Designed with a flat or concave end, they are perfect for parts with high hardness or those requiring frequent adjustment, like metal bearings.

Column End: A cylindrical end crafted for the axial fixation of tubular shaft components, ensuring robust support.

2. Drive Slot Type:

Hexagon: Utilized with an Allen wrench, it provides stable torque transmission, making it the most versatile and widely applicable choice.

One Slot: Compatible with standard screwdrivers, it is well-suited for scenarios where space is limited.

3. Material and Specifications

Material: Available in common carbon steel (45 #), stainless steel (SUS304), and corrosion-resistant brass, with surface treatments such as galvanization or blackening.

Specification: Diameter ranges from M1.6 to M10, with lengths spanning 4mm to 100mm. Options include concave end, flat end, and more for tailored applications.

------

4. Application Scenarios

Mechanical Manufacturing: Secure shaft components like bearings and gears, preventing unwanted axial movement.

• Automation Equipment: Seamlessly integrates with automatic screw machines for the swift assembly of electronic components and lightweight structures.

Precision Instruments: Facilitates micro-adjustment positioning in microscope focusing mechanisms and optical equipment, offering precision like never before.

5. Installation Specifications

Tool Adaptation: Ensure that the hexagonal shape is perfectly matched with the wrench size to prevent any damage from slipping teeth.

• Compression Force Control: The tapered screw's compression force is relatively modest, whereas the flat/concave end can endure higher loads. Selection should consider material hardness.

In conclusion, machine rice screws stand as pivotal fastening solutions in the realms of mechanical assembly and precision manufacturing, thanks to their compact design, versatile end types, and exceptional adaptability.
