What Are Industrial Pins?
Industrial pins are mechanical fasteners designed to secure, align, connect, or lock components. Unlike permanent fasteners, many Retaining Pins offer quick installation and removal, making them ideal for applications that require regular assembly, maintenance, or adjustment.
Common industries using Retaining Pins include:
- Agriculture
- Construction and scaffolding
- Formwork systems
- Transportation and trailers
- Industrial machinery
- Material handling equipment
- Marine applications
