The construction industry is rapidly adopting Mivan Aluminium Formwork Systems for faster project execution, higher-quality concrete finishes, reduced labour costs, and repetitive construction cycles. One of the most important accessories that ensures the stability and alignment of aluminium formwork panels is the Stub Pin and Wedge.

A Stub Pin and Wedge is a reusable locking component used to securely connect adjacent aluminium formwork panels. Together, the stub pin and wedge provide a rigid and stable connection that withstands concrete pressure during pouring while maintaining accurate wall dimensions and alignment.

Also known as Mivan Stub Pin, Mivan Wedge Pin, Aluminium Formwork Pin, Formwork Stub Pin, Pin & Wedge for Mivan, Shuttering Pin and Wedge, Concrete Formwork Fastener, Mivan Formwork Accessories, Formwork Locking Pin, and Aluminium Formwork Connector, these accessories are extensively used in residential towers, commercial buildings, affordable housing projects, bridges, metro stations, precast construction, and infrastructure developments.

TRP Machines & Tools, Mumbai, Maharashtra, India, supplies precision-engineered Stub Pins and Wedges manufactured from high-strength steel with accurate dimensions, superior strength, and excellent durability for demanding construction environments.

A Stub Pin and Wedge is a reusable fastening accessory used in Mivan aluminium formwork systems to securely lock adjoining formwork panels. It ensures panel alignment, structural stability, faster installation, and superior concrete finishing during construction.

A Stub Pin and Wedge is a precision-engineered fastening system used to connect aluminium formwork panels. The stub pin passes through aligned holes in adjacent panels, while the wedge is inserted through the pin to create a firm mechanical lock.

This locking mechanism prevents panel movement, ensures accurate alignment, and maintains the integrity of the formwork during concrete placement.

Fresh concrete exerts considerable pressure on formwork. Any movement in the panels can result in honeycombing, leakage, dimensional errors, and poor concrete finish.

Using Stub Pins and Wedges helps:

• Secure aluminium formwork panels
• Maintain proper panel alignment
• Prevent movement during concrete pouring
• Reduce grout leakage
• Improve dimensional accuracy
• Increase construction speed
• Ensure worker safety
• Support multiple reuse cycles

1. 01Align Formwork PanelsPosition adjacent aluminium formwork panels correctly.
2. 02Insert the Stub PinPass the stub pin through the aligned holes in the panels.
3. 03Insert the WedgeDrive the wedge into the opening provided in the stub pin.
4. 04Lock the ConnectionThe wedge creates a tight locking action that firmly secures both panels.
5. 05Pour ConcreteThe locked panels remain stable under concrete pressure.
6. 06Remove After Concrete SettingAfter stripping the formwork, remove the wedge and stub pin for reuse.
