Product Description

Effortlessly secure your constructions with our machine rice screws! Designed for precision and enduring reliability, these small-yet-mighty fasteners are ideal for a vast array of mechanical applications, offering unparalleled stability and strength.

Machine mounted screws, alternatively referred to as set screws, stop screws, or headless screws, are sophisticated fasteners crafted without a head, playing a crucial role in the precise axial positioning and secure fixation of mechanical components. They efficiently transmit loads through end compression and effectively prevent loosening of assembled components. Discover their core features and classifications below:

------

1, Basic Definition

Machine rice screws derive their name from their diminutive size, akin to grains of rice, and typically feature a headless design. They require tightening with specialized tools, such as hexagonal or slotted screwdrivers, to ensure a snug and reliable fit.
These screws serve critical purposes, including:

Fixed positioning: Once inserted into a screw hole, the screw end firmly presses against another component's surface, effectively limiting any potential relative displacement.

Anti-loosening effect: Certain models are ingeniously designed with stop washers or unique thread patterns, significantly enhancing their vibration resistance capabilities.

Structural Features

1. End type:

Cone end: Featuring a sharp tip, this is ideal for the compression and positioning of materials with lower strength, like plastics, ensuring secure fastening.

Flat end/concave end: Designed with either a flat or concave end, they are perfect for parts that possess high hardness or need frequent adjustments, such as metal bearings.

Column end: This cylindrical end is specifically used for the robust axial fixation of tubular shaft components, maintaining firm alignment.

2. Drive slot type:

Hexagon: Operable with an Allen wrench, this type provides stable torque transmission and is versatile for a wide variety of applications.

One slot: Compatible with standard screwdrivers, this is ideal for situations with limited space where maneuverability is constrained.

3, Material and specifications

Material: Available in durable carbon steel (45 #), stainless steel (SUS304), and corrosion-resistant brass, with surfaces that can be galvanized or blackened for enhanced resilience.

Specification: Diameters range from M1.6 to M10, with lengths spanning from 4mm to 100mm, and including variations like concave end, flat end, and more.

------

4, Application scenarios

Mechanical manufacturing: Essential for fixing shaft components like bearings and gears, preventing any unwanted axial movement.

• Automation equipment: Seamlessly integrates with automatic screw machines, enabling rapid assembly of electronic components and lightweight structures.

Precision instruments: Facilitates micro-adjustment positioning in complex devices such as microscope focusing mechanisms and optical equipment.

5, Installation specifications

Tool adaptation: Ensure the hexagonal screw is perfectly matched to the wrench size to prevent damage from slipping teeth, maintaining integrity.

• Compression force control: Tapered screws apply less force and are suited for materials with lower hardness, while flat/concave ends can endure higher loads, chosen based on specific material hardness requirements.

In conclusion, machine rice screws stand out as indispensable fastening solutions in mechanical assemblies and precision manufacturing, thanks to their compact yet versatile design, varied end types, and outstanding adaptability.
