What is a Stub Pin and Wedge?
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.
Why is a Stub Pin and Wedge Important?
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:
How Does a Stub Pin and Wedge Work?
Step 1 – Align Formwork Panels
Position adjacent aluminium formwork panels correctly.
Step 2 – Insert the Stub Pin
Pass the stub pin through the aligned holes in the panels.
Step 3 – Insert the Wedge
Drive the wedge into the opening provided in the stub pin.
Step 4 – Lock the Connection
The wedge creates a tight locking action that firmly secures both panels.
Step 5 – Pour Concrete
The locked panels remain stable under concrete pressure.
Step 6 – Remove After Concrete Setting
After stripping the formwork, remove the wedge and stub pin for reuse.
