Stainless steel 304 cross-head slotted pins/pins (including circlip locating studs/cylinders) are a versatile fastener with the following core functions and applications.
I. Core Functions
Mechanical Positioning and Fixing
Axial Positioning: The cylindrical portion of the pin mates with the hole to achieve precise alignment between parts.
Radial Fixing: The circlip groove design allows for the installation of a circlip to prevent axial movement, replacing the nut for locking.
Anti-Rotation: The cross-head or slotted design allows for tool adjustment to prevent loosening during use.
Modular Assembly: Standardized dimensions facilitate modular design of industrial equipment, facilitating quick replacement and maintenance.
Corrosion Resistance and Durability: 304 stainless steel is acid- and alkali-resistant, rust-resistant, and suitable for use in humid (e.g., food processing) or chemical environments.
Load-bearing and shear resistance
The cylindrical structure withstands radial loads, and high-precision tolerances ensure stability.
II. Functional Differences among Sub-Models
Model Typical Applications Functional Focus
M3-M4: Electronics, precision instruments (such as optical equipment), Micro positioning, light load fixation
M5-M6: Automation equipment, 3D printer component, Medium loads, frequent assembly and disassembly
M8-M10: Heavy machinery, conveyor belt bearing seat, High shear force resistance, vibration resistance
III. Key Design Features
Flat cross head: Easily applies torque during installation, reducing wear on the workpiece surface.
Circlip Groove: Standardized groove width, compatible with common circlips.
Full Thread/Half Thread: The half-threaded version enhances guidance in the unthreaded section, while the full-threaded version offers flexible adjustment.
IV. Selection Considerations
Load Compatibility: The M10 can handle dynamic loads > 500 kg and static loads > 1 ton.
Environmental Compatibility: 316 stainless steel is recommended for high-temperature environments, although this increases cost, but improves corrosion resistance.
Groove depth accuracy: A key parameter that influences the secure installation of the circlip.
V. Typical Application Cases
Automation guide rails: M6 pins + circlips secure the slider stop.
Agricultural machinery hinges: M10 nickel-plated pins resist muddy water corrosion, and the circlips prevent disengagement.
Through the above design, this fastener achieves a balance of precision, strength, and adaptability, making it an ideal choice for mechanical transmission and structural connections.
