Product Description

An Overview of Machine Rice Screws

Machine mounted screws, which are also popularly known as set screws, stop screws, or headless screws, are a specialized category of fasteners. With a sleek, headless design, these screws are predominantly utilized for axial positioning and securing mechanical components in place. Not only do they transmit loads via end compression, but they also excel at preventing loosening. Dive into their core features and classifications to discover what sets them apart:

------

1, Fundamental Definition

Machine rice screws derive their unique name from their diminutive size, reminiscent of rice grains. Typically devoid of a head structure, these screws require tools like hexagonal or slotted screwdrivers for tightening.
Their key functions encompass:

Fixed Positioning: When screwed into the intended component's hole, the screw's end presses firmly against the surface of an adjacent component, effectively restricting any relative movement.

Anti-Loosening Capability: Certain models integrate stop washers or boast specialized thread designs that significantly bolster vibration resistance.

Structural Distinctions

1. End Configuration:

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

Flat End/Concave End: These are perfect for components requiring high hardness or frequent adjustments, like metal bearings.

Column End: A cylindrical end designed for axial stabilization of tubular shaft components.

2. Drive Slot Variations:

Hexagon: Designed for use with an Allen wrench, this slot ensures stable torque transmission and broad applicability.

Single Slot: Compatible with standard screwdrivers, it's ideal for scenarios where space is a premium.

3, Material and Specifications

Material: Options include common carbon steel (45 #), stainless steel (SUS304), and brass, which is resistant to corrosion. Surfaces can undergo galvanization or blackening.

Specifications: The diameter ranges from M1.6 to M10, with lengths spanning 4mm to 100mm. These are further subdivided into types like concave end, flat end, among others.

4, Diverse Application Scenarios

Mechanical Manufacturing: These screws proficiently fix shaft components, such as bearings and gears, to avert axial movement.

• Automation Equipment: They seamlessly partner with automatic screw machines to swiftly assemble electronic components and lightweight structures.

Precision Instruments: They facilitate micro-adjustment and positioning within microscope focusing mechanisms and optical apparatus.

5, Installation Specifications

Tool Compatibility: Ensure that the hexagonal shape aligns perfectly with the wrench size to prevent any damage caused by slipping teeth.

• Compression Force Management: While the tapered screw end can handle relatively lighter compression forces, the flat/concave end is designed to endure heavier loads. Selection should be tailored to the material's hardness.

In conclusion, machine rice screws have emerged as indispensable fastening solutions in mechanical assembly and precision manufacturing. Their compact design, variety of end types, and extensive adaptability make them essential in numerous applications.
