Custom Spring Pins are fastening components with a self-locking function, widely used in mechanical assemblies, bearings, drive systems, and other applications requiring reliable positioning and fixation. The unique spring structure of the pin provides additional tension during installation, ensuring the component remains securely in place.


Product Features:
1. High Elasticity: Made from high-elasticity materials, the spring pin can effectively bear dynamic loads and provide sufficient fastening and holding force.
2. Self-locking Design: Thanks to its spring properties, the pin provides a strong self-locking effect after installation, effectively preventing loosening.
3. Tool-free Installation: The spring pin is easy to install without the need for tools. It can be quickly inserted into the matching hole with just pressure, saving time and effort.
4. Durability: Generally made from high-strength stainless steel or alloy steel, the pin offers excellent corrosion resistance and long service life.
5. Customizable Design: We provide customization options for size, material, and surface treatment according to the customer’s needs, meeting various industry requirements and applications.
6. Precise Tolerance: Our spring pins are manufactured to precise dimensional tolerances, ensuring accuracy and stability during installation.

Pin Types Overview Table


Pin Type
Definition
Applications
Features
Spring Pin
A pin shaped like a spring, made of compressed steel or stainless steel, designed to be compressed during installation and then
return to its original shape, providing clamping force to prevent loosening.
Used in mechanical assemblies, automotive, agricultural machinery, and other fields requiring quick installation, disassembly, and
elastic fastening.
Easy to install, good vibration resistance, suitable for high-frequency use and quick disassembly.
Lock Pin
A pin equipped with a locking device, such as a spring or lock plate, to prevent loosening or detachment. Typically features a
ring-like part for locking.
Commonly used in applications where secure, non-loosening connections are required, widely used in machinery, aviation, and
automotive sectors.
Self-locking function prevents loosening, easy installation and removal.
Dowel Pin
A cylindrical pin with high precision, primarily used for accurate positioning of two parts or securing the location of
components, usually under light load.
Widely used in machinery, especially for precise alignment or positioning in molds, machine components, and assembly processes.
High dimensional accuracy, typically installed in holes for precise component positioning.
Cotter Pin
A U-shaped pin, usually made of metal, inserted into a shaft or hole and bent at both ends to secure it in place, preventing parts
from coming off.
Commonly used in automotive, motorcycles, and industrial machinery to connect parts, especially in applications requiring easy
disassembly.
Simple to install and remove, but not suitable for high-load or high-precision connections.
Non-standard Pin
A pin custom-made according to specific requirements, differing from standard pins in terms of size, shape, material, or design.
Used in special mechanical structures or engineering designs where standard pins cannot be applied.
Customizable according to customer needs, ideal for unconventional applications.
Knurled Pin
A pin with a roughened surface or texture, increasing friction between the pin and the hole, improving clamping force and
anti-slippage ability.
Mainly used in automotive, machinery, and other applications where additional friction and anti-slippage are needed for connection
and fixation.
Special textured surface design provides strong clamping force, preventing loosening.
Clevis Pin
A pin with a ring or hook shape at one end for easy connection with other parts, typically used in conjunction with nuts or other
pins for locking.
Commonly used in agricultural machinery, construction equipment, and lifting devices to fix and connect components.
Typically used for larger mechanical components, easy to disassemble and install, with a ring design that can be locked with a pin
or hook.
Cylindrical Pin
The most common type of pin, typically cylindrical in shape and small in size, used for securing and connecting components.
Widely used in mechanical assemblies, electronics, automobiles, and other industries, especially as a connector or locator.
Simple structure, suitable for securing and positioning, typically used in hole fits.
