Product Description

Description of Machine Rice Screws

Machine mounted screws, commonly called set screws, stop screws, or headless screws, are uniquely designed fasteners perfect for those seeking a headless design. They primarily fulfill the role of axial positioning and securing mechanical components by transmitting loads through end compression, effectively preventing any unwanted loosening. Let’s explore their standout features and classifications:

------

1, Basic Definition

Machine rice screws take their name from their diminutive, rice-grain-like size. Designed without a head structure, they require specific tools like hexagonal or slotted screws for proper tightening.
Key Functions Include:

Fixed Positioning: Once screwed into the designated hole of the component, they press firmly against another component's surface, effectively limiting any relative displacement.

Anti-Loosening Effect: Select models incorporate stop washers or uniquely designed threads to bolster vibration resistance and ensure stability.

Structural Features

1. End Type:

Cone End: Features a sharp tip, ideal for compression positioning in materials of lower strength, such as plastics.

Flat End/Concave End: With flat or concave ends, they are perfect for high-hardness parts or those requiring frequent adjustments, such as metal bearings.

Column End: Designed with a cylindrical end, it’s used for axial fixation in tubular shaft components.

2. Drive Slot Type:

Hexagon: Enables operation with an Allen wrench, ensuring stable torque transmission across a broad range of applications.

One Slot: Compatible with standard screwdrivers, this design is advantageous in space-restricted scenarios.

3, Material and Specifications

Material: Typically crafted from common carbon steel (45 #), stainless steel (SUS304), or corrosion-resistant brass. Surfaces can be treated with galvanization or blackening for enhanced durability.

Specification: Diameters range from M1.6 to M10, with lengths from 4mm to 100mm, and are available in types like concave end and flat end.

4, Application Scenarios

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

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

Precision Instruments: Achieves micro-adjustment positioning in devices like microscope focusing mechanisms and optical equipment.

------

5, Installation Specifications

Tool Adaptation: Ensure the hexagonal shape aligns with the wrench size to prevent tooth slipping and potential damage.

• Compression Force Control: Tapered screws offer limited compression force, while flat/concave ends can handle higher loads. Selection should be based on material hardness for optimal performance.

In conclusion, machine rice screws stand as indispensable components in mechanical assembly and precision manufacturing due to their compact design, diverse end types, and remarkable adaptability.
