Product Description

Unveiling the Intricacies of Machine Rice Screws

Machine mounted screws, often referred to as set screws, stop screws, or headless screws, are sophisticated fasteners featuring a headless design. They are quintessential in the axial positioning and securing of mechanical components, effectively transmitting loads through end compression and adeptly preventing loosening. Explore its exceptional core attributes and classifications:

------

1, Basic Definition

Referred to as machine rice screws due to their diminutive size akin to rice grains, these screws typically lack a head structure, necessitating the use of specialized tools like hexagonal or slotted screws for tightening.
These screws perform essential functions, including:

Fixed positioning: Once embedded in the screw hole of the target component, the screw's end is pressed firmly against another component's surface to restrict relative movement, ensuring a steadfast hold.

Anti-loosening mechanism: Select models incorporate stop washers or unique thread designs to bolster vibration resistance, ensuring stability under dynamic conditions.

Structural Features

1. End type:

Cone end: Characterized by a sharp tip, this type is ideal for compression positioning in low-strength materials such as plastics, ensuring a secure fit.

Flat end/concave end: Designed with a flat or concave profile, these ends are suited for high-hardness parts or those requiring frequent adjustments, like metal bearings.

Column end: Featuring a cylindrical end, it is perfect for the axial fixation of tubular shaft components, ensuring robust alignment.

2. Drive slot type:

Hexagon: Utilized with an Allen wrench, it facilitates stable torque transmission and enjoys the broadest range of applications.

One slot: Optimized for use with ordinary screwdrivers, these are perfect for scenarios where space is at a premium.

3, Material and specifications

Material: Crafted from common carbon steel (45 #), stainless steel (SUS304), or corrosion-resistant brass, these screws can be finished with galvanization or blackening for enhanced durability.

Specification: Ranging from diameters M1.6 to M10 and lengths from 4mm to 100mm, these screws are available in diverse types, including concave and flat ends.

------

4, Application scenarios

Mechanical manufacturing: Essential for securing shaft components such as bearings and gears, preventing unwanted axial movement and ensuring operational precision.

• Automation equipment: In synergy with automatic screw machines, they facilitate the rapid assembly of electronic components and lightweight structures, streamlining manufacturing processes.

Precision instruments: Key in micro-adjustment positioning within microscope focusing mechanisms and optical equipment, these screws ensure precision and reliability.

5, Installation specifications

Tool adaptation: Ensure that the hexagonal shape of the screw is perfectly matched with the appropriate wrench size to prevent damage from slipping teeth, maintaining the integrity of your installation.

• Compression force control: With the tapered screw exerting comparatively low compression force, and the flat/concave end accommodating higher loads, select the appropriate type based on material hardness for optimal performance.

In conclusion, machine rice screws have become indispensable in mechanical assembly and precision manufacturing, thanks to their compact design, diverse end types, and remarkable adaptability across a multitude of applications.
