Watch: Long Mivan Stub Pin vs Regular Stub Pin Comparison
Before selecting a stub pin for your next project, watch this quick comparison video showing the difference between a 127mm Long Mivan Stub Pin and a 50mm Regular Stub Pin used in Mivan formwork systems.
What is a Stub Pin in Mivan Formwork?
A stub pin is a fastening component used in aluminum formwork systems and Mivan construction. It works together with wedges to securely connect adjoining panels during concrete pouring.
Without properly fitted stub pins:
- Panels may shift during concreting
- Alignment can be affected
- Structural accuracy may suffer
- Installation time increases
- Safety risks may increase
Modern Mivan construction depends heavily on high-quality stub pins for reliable performance and repeated usage.
Types of Stub Pins Used in Formwork

| High-Rise Projects | Ideal | Suitable |
| Installation Speed | Moderate | Faster |
| Cost | Higher | Lower |
Which Stub Pin Do Most Contractors Prefer?
Contractors working on residential towers and repetitive construction cycles generally use 50mm stub pins because they are fast to install and economical.
However, for infrastructure projects, commercial buildings, metro construction, bridges, and export projects, many engineers prefer 127mm stub pins because of their improved engagement length and enhanced stability.
The final choice depends on project requirements, panel configuration, and site conditions.
When Should You Use a 127mm Long Stub Pin?
- High-rise residential towers
- Commercial buildings
- Metro projects
- Bridge construction
- Infrastructure projects
- Heavy concrete pressure applications
- Critical structural sections
When Is a 50mm Stub Pin Enough?
- Residential projects
- Standard aluminum formwork systems
- Daily repetitive construction cycles
- Rapid installation projects
- Cost-sensitive developments
