Long Description

Our OEM & ODM Spring Pins are engineered for high-precision mechanical fastening, offering excellent elasticity, durability, and self-locking performance. Manufactured from premium spring steel or stainless steel, our slotted and coiled spring pins fit tightly into pre-drilled holes, providing consistent tension and a reliable connection even under vibration, shock, or dynamic load.

Spring pins are widely used in industrial machinery, automotive components, tools, hardware equipment, electrical devices, and other mechanical systems requiring secure alignment and fastening. Every pin is produced with strict dimensional tolerance, chamfered ends for smooth installation, and surface treatments tailored to your application (zinc plating, black oxide, passivation, etc.).

We support full OEM/ODM customization, including materials, dimensions, finishes, packaging, and private labeling. Whether you are a distributor, wholesaler, or manufacturer, we offer competitive pricing and fast lead times to meet your production needs.

      FAQ

      Q1: What is the difference between slotted and coiled spring pins?

      Slotted pins have a single slot, while coiled pins are spirally wound for higher flexibility and shock absorption. Coiled pins perform better under dynamic loads.

      Q2: Can I customize the diameter and length?

      Yes. We provide full OEM/ODM customization according to your drawings or samples.

      Q3: What materials do you offer?

      Carbon steel, stainless steel (304/316), alloy steel, and other materials upon request.

      Q4: What is your MOQ?

      MOQ is flexible—small trial orders are accepted for custom sizes.

      Q5: Do you provide samples?

      Yes, samples can be provided for quality testing before mass production.

      Q6: Which industries commonly use spring pins?

      Automotive, machinery, tools, hardware equipment, electrical devices, robotics, and more.
