Products Description

Micro Flat Head Screws are small fasteners designed specifically for high-precision, miniaturized devices. Their flat heads allow them to sit flush with the connected surface after installation, eliminating protrusions that would otherwise affect the overall aesthetics and compactness of the structure. These screws are widely used in electronic equipment, precision instruments, optical components, medical devices, smart homes, and micro-machinery, and are particularly well-suited for applications with limited space, precise structures, and high precision requirements. Our micro flat head screws are crafted from high-quality stainless steel and processed through precision cold heading, turning, and surface treatment. They offer excellent mechanical properties, corrosion resistance, and dimensional consistency, making them essential components in the assembly of various micro-devices.

core advantages

Micro-Precision Manufacturing: Strict Tolerance Control for Error-Free Assembly

Our Flat Head Screws boast thread accuracy exceeding ISO 6g, ensuring efficient fit in nuts or pre-formed holes.

The flat head is CNC-finished for a sharp contour and uniform chamfers, effectively preventing assembly interference.

The length range supports a ±0.02mm tolerance, making it ideal for assembly in micro-devices with demanding dimensional requirements.

Flat, Low-Head Design: No Protrusion, No Interference

The flat head design allows the Flat Top Screw head to be installed flush with the workpiece surface, eliminating protrusions that affect aesthetics or interfere with moving parts.

Suitable for applications where overall surface flatness or close contact with components is critical, such as PCBs, precision sensors, and display modules.

Combined with standard or custom countersunk holes, it maximizes space utilization.

High-Strength Materials: Small Screws, High Tensile Strength

We offer a variety of materials, including stainless steel (SUS304, SUS316), titanium alloy, copper alloy, carbon steel, and alloy steel, tailored to customer needs.

Even tiny Low Profile Flat Heads offer high tensile strength and shear resistance, ensuring long-term, stable service in microstructures.

We offer a wide range of surface treatments, including nickel plating, blackening, zinc plating, and corrosion-resistant coatings, to adapt to various working environments.

Strict Selection of Steel Wire for Micro Flat Head Screw

Product Structural Features Analysis: Small yet Capable of Big, Functional Integration

Despite its small size, the miniature Flat Head Machine Screw boasts an ingenious design. From the bevel angle of the head, the pitch precision of the threads, to the machining of the tail, all reflect the manufacturer's technical expertise and meticulous craftsmanship. It must ensure reliable locking in confined spaces while preventing structural damage from over-insertion. Therefore, the flat head structure, combined with a precise countersink depth, not only improves assembly efficiency but also effectively protects the underlying load-bearing components.

Wide-ranging applications require professional fastening

Consumer Electronics

Thin Flat Head Screws are used for micron-level fastening in mobile phones, smart wearables, TWS earphones, drones, and electronic modules. Their flat-head design allows for interference-free installation of patches, slides, and housings, enhancing the overall aesthetics and reliability of the device.

Medical Device Manufacturing

Micro fasteners are used to connect core components such as micro sensors, motor mounts, and wire guides in minimally invasive surgical equipment, in vitro testing instruments, and portable diagnostic and treatment devices. Their non-magnetic material options ensure stable operation in high-precision medical environments.

Precision Industrial Equipment

Microscopic instruments, optical modules, semiconductor test fixtures, and other applications all place high demands on fasteners that are both invisible and precise. Flat Face Screws provide high-strength connections while ensuring zero interference, making them key to modular design.

Automation and Robotics
Flat Head Screws are widely used for structural locking and motion fixation in micro actuators, transmission slides, and motor mounting plates. They can effectively withstand repeated vibration and continuous displacement, meeting stringent industrial motion standards.

Aerospace
In small flight control systems, attitude control modules, and avionics assembly components, Flat Top Screw' high strength, lightweight, and corrosion resistance meet aviation-grade fastening standards.
