Product overviewOverview
A spring pin works by radial elasticity: its free diameter is slightly larger than the hole, so pressing it in compresses the pin and the spring-back grips the bore. That grip provides retention and absorbs hole and pin tolerance, which makes assembly easier than with a solid dowel and gives some damping under shock.
Material: Customized per specification. It is pressed into the hole, where spring force holds it.
Key featuresFeatures
- Radial elasticity absorbs hole tolerance, easing assembly.
- Coiled construction is compliant and suits repeated disassembly.
- Seamless construction carries higher shear loads.
- Spring grip resists walking out under vibration.
Typical applicationsApplications
- Mould and fixture location
- Hinge and linkage joints
- Machine pin joints
Selection notesSelection
Choose coiled pins for repeated disassembly and seamless pins for heavy shear.
Frequently asked questionsFAQ

What matters during installation of the Elastic Dowel Pin (Elastic Positioning Pin)?
| Material | Customized per specification |
|---|---|
| Surface Treatment | As required |
| Standard | GB/T 879 series (spring pins) |
| Installation | pressed into the hole, held by spring force |
| Typical substrate | moulds, fixtures, linkage location |
| Key inspections | diameter, insertion/push-out force, shear strength |
Outside diameter, length and slot form checked to the GB/T 879 series.We recommend a pilot assembly at the actual torque and mating part before locking the process parameters for volume.
