A Brass Stub Pin is a small, cylindrical fastener used in construction and formwork applications. It is typically used to secure two pieces of formwork or shutter together, such as when building a concrete wall or column. The stub pin is made of brass, which is a corrosion-resistant material that is also strong and durable. The Brass Stub Pin is usually about 50mm to 100mm in length and has a diameter of around 10mm to 15mm.
