Product Description

Description of Machine Rice Screws

Machine mounted screws, also known as set screws, stop screws, or headless screws, are indispensable fasteners due to their ingenious headless design. Primarily utilized for precise axial positioning and secure fixation of mechanical elements, they effectively transmit loads via end compression and prevent unwanted loosening. Below, we highlight their essential features and classifications:

------

1, Basic Definition

Machine rice screws derive their unique name from their rice-like miniature size, typically lacking a head structure. These screws require tightening with specialized tools such as hexagonal or slotted drivers, catering to their intricate design.
Its Functions Include:

Fixed Positioning: Once inserted into the designated screw hole, the screw's end firmly presses against the surface of an adjacent component, effectively limiting any relative displacement.

Anti-Loosening Effect: Certain variants are ingeniously paired with stop washers or feature special thread designs to significantly enhance resistance against vibrations.

Structural Features

1. End Type:

Cone End: This sharp-tipped variant is ideal for compressing and positioning low-strength materials like plastics.

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

Column End: Featuring a cylindrical shape, this type is perfect for axial fixation within tubular shaft components.

2. Drive Slot Type:

Hexagon: Operable using an Allen wrench, this type ensures stable torque transmission and is suitable for a wide range of applications.

One Slot: Designed for standard screwdrivers, this type is ideal for scenarios where space is limited.

3, Material and Specifications

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

Specification: With diameters ranging from M1.6 to M10 and lengths from 4mm to 100mm, these screws are further categorized into concave end, flat end, and other types.

------

4, Application Scenarios

Mechanical Manufacturing: These screws are pivotal in fixing shaft components like bearings and gears, preventing any axial movement.

• Automation Equipment: They seamlessly work with automatic screw machines for rapid assembly of electronic components and lightweight structures.

Precision Instruments: They enable micro-adjustment positioning in devices such as microscope focusing mechanisms and optical equipment.

------

5, Installation Specifications

Tool Adaptation: Ensure the hexagonal shape matches the wrench size to avoid any damage due to slipping teeth during tightening.

• Compression Force Control: While the tapered screw exerts minimal compression force, the flat/concave end can endure higher loads. The appropriate type should be chosen based on the material's hardness.

In summary, due to their compact design, diverse end types, and high adaptability, machine rice screws have solidified their role as key fastening components in mechanical assembly and precision manufacturing.
