Customized Galvanized Spring Steel Small Coil Compression Spring for

Description

Product Overview

Our customized galvanized spring steel coil is engineered for precision and durability. With a wire diameter of 0.4 mm, an outer diameter of 4 mm, and a total length of 30 mm, this small coil delivers consistent compression force in a compact form factor.

The spring is fabricated from high‑grade galvanized steel, providing excellent corrosion resistance and a long service life even in harsh environments. The galvanization process creates a protective zinc layer that shields the spring from moisture, chemicals, and wear, making it ideal for industrial and scientific applications where reliability is paramount.

Designed for ball pens, miniature mechanisms, and other tight‑space assemblies, the spring’s geometry ensures smooth operation and repeatable performance. Its dimensions are carefully calibrated to fit standard pen housings and similar devices, reducing the need for additional modifications or custom tooling.

Each batch is produced under strict quality‑control standards, adhering to the specifications of model CS‑20200811. The springs are packaged in sets of 100 pieces, each individually inspected for dimensional accuracy and material integrity.

Our manufacturing process incorporates precision coiling equipment that maintains tight tolerances on wire gauge and coil spacing. This results in a uniform spring constant across the entire lot, guaranteeing that every unit performs identically in the field.

In addition to the core specifications, the product includes detailed packaging dimensions of 2.64 × 2.6 × 0.87 inches and a lightweight of 0.63 ounces per set, facilitating easy storage and shipping.

Usage

The spring excels in applications that require a reliable compression force within a limited space. Typical uses include ball‑point pen mechanisms, miniature actuators, micro‑switches, and small‑scale robotics where precise movement is essential.

Engineers and designers can integrate the spring into prototypes or final products without concern for premature fatigue. Its corrosion‑resistant coating makes it suitable for outdoor tools, laboratory equipment, and any setting where exposure to humidity or chemicals is expected.</n

Because of its consistent spring rate, the coil can be used in calibration devices, tensioning systems, and as a preload element in mechanical assemblies. The spring’s compact size also allows it to be stacked or combined with other components to achieve custom force profiles.

When assembling, simply insert the spring into the designated cavity of the pen or device, ensuring that the ends are aligned with the housing guides. No additional lubrication is required, as the galvanized surface provides low friction and protects against wear.
