Product Description

Description of Machine Rice Screws

Machine mounted screws, often referred to as set screws, stop screws, or headless screws, stand as a remarkable type of fastener embodying a headless design. Engineered primarily for precise axial positioning and secure fixation of mechanical components, these screws are adept at transmitting loads through end compression while effectively preventing loosening. Discover its standout core features and classifications below:

------

1. Basic Definition

Machine rice screws derive their name from their diminutive size, akin to tiny grains of rice, and characteristically lack a head structure. They necessitate the usage of specialized tools such as hexagonal or slotted drivers for tightening.
Its functions include:

Fixed Positioning: Once driven into the component's screw hole, these screws press the end firmly against another component's surface, effectively limiting any relative displacement.

Anti-Loosening Effect: Certain models are ingeniously designed with stop washers or specialized threads to significantly enhance vibration resistance.

Structural Features

1. End Type:

Cone End: Featuring a sharp tip, this design is ideal for compressive positioning in low-strength materials like plastics.

Flat End/Concave End: With flat or concave design, these ends are suitable for high-hardness parts or those necessitating frequent adjustments, such as metal bearings.

Column End: Employed for axial fixation of tubular shaft components, boasting a cylindrical end design.

2. Drive Slot Type:

Hexagon: Engineered for operation with an Allen wrench, facilitating stable torque transmission and boasting a broad spectrum of applications.

One Slot: Designed for ordinary screwdrivers, this type is optimal for scenarios where space is at a premium.

3. Material and Specifications

Material: Fabricated from common carbon steel (45#), stainless steel (SUS304), or brass known for its corrosion resistance. Surface treatments include galvanization or blackening.

Specification: Available in diameter ranges from M1.6 to M10, and lengths spanning 4mm to 100mm. They are further classified into various end types, including concave and flat ends.

4. Application Scenarios

Mechanical Manufacturing: Essential for securing shaft components such as bearings and gears, effectively preventing axial movement.

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

Precision Instruments: Plays a crucial role in achieving micro-adjustment positioning, especially in microscope focusing mechanisms and optical equipment.

5. Installation Specifications

Tool Adaptation: It is crucial to match the hexagonal shape with the appropriate wrench size to prevent damage from slipping teeth.

• Compression Force Control: The tapered screw's compressive force is relatively modest, whereas the flat/concave end can withstand higher loads. Selection should be based on material hardness.

In summary, machine rice screws have emerged as pivotal fastening components in both mechanical assembly and precision manufacturing. Their compact design, diverse end types, and remarkable adaptability make them indispensable.
