The construction standard aluminum formwork wedge pin, frequently referred to as a locking pin or stub pin, serves as the critical anchoring component in modern concrete pouring operations. Forged from premium carbon steel or 45# steel, this solid metal connector works in tandem with a wedge to securely interlock adjoining formwork panels. When handled, the pin presents a dense, reassuring weight and a smooth, burr-free surface that speaks to its precise machining. It is engineered to slide effortlessly through pre-drilled panel holes without snagging.
Once the wedge is driven into the pin's precisely milled slot, it creates an unyielding mechanical bind. This fastening system is universally compatible with major aluminum formwork frameworks, including US and South Korean standard systems, and integrates flawlessly with flat ties and wall ties. By eliminating panel displacement and preventing concrete slurry leaks under immense pressure, these pins ensure the structural integrity and exact dimensional alignment of the final concrete pour, providing contractors with a highly reliable, one-stop fastening solution.
The intuitive slide-and-lock mechanism drastically reduces assembly and dismantling times. Workers can rapidly secure panels with a simple hammer strike, accelerating the overall project timeline and optimizing labor utilization on demanding construction sites.
Featuring a meticulously angled slot, the pin accommodates the wedge to form an exceptionally tight friction fit. This prevents any micro-shifting or vibration-induced loosening when heavy, wet concrete is poured into the molds.
Enhanced by advanced surface treatments such as galvanization or black oxide coating, these pins resist rust and corrosion even when exposed to damp, alkaline concrete environments. This surface protection significantly extends their operational lifespan.
Designed for heavy-duty repetitive cycles, the solid metal construction resists deformation. Contractors can confidently strip and reuse these connectors across dozens of project phases, maximizing the return on investment.
Manufactured through professional heat treatment processes, the pins achieve specific tensile strength and ultimate load capacities. This guarantees they can withstand the immense hydrostatic pressure of curing concrete without snapping.
The straightforward, solid-state design lacks fragile moving parts, requiring little more than a quick wash to remove concrete residue before being deployed for the next application.
While steel options offer maximum load-bearing, the available aluminum variations provide a lighter alternative that reduces operator fatigue during extensive manual handling and lowers overall transit weights.
Every single batch of our formwork wedge pins is subjected to rigorous quality control protocols. We strictly enforce ISO/CE/SGS international testing standards, conducting comprehensive factory inspections and ultimate tensile strength evaluations before shipment.

Drawing on over 15 years of source-factory manufacturing expertise, our production facilities are fully equipped to handle massive volume requirements. We maintain a monthly production capacity reaching tens of millions of sets, allowing for highly flexible scheduling during peak construction seasons to ensure rapid response and on-time delivery for large-scale procurement.
Our global footprint extends to infrastructure projects across the Americas, Europe, Japan, South Korea, and Southeast Asia. To guarantee the products arrive in pristine condition, we utilize a standardized export packaging protocol involving moisture-resistant wrapping, secure strapping, and heavy-duty plywood boxes. This palletized approach not only protects the metal components from maritime humidity but also facilitates highly efficient forklift loading and unloading directly at the construction site.
We operate as a direct manufacturing facility with over 15 years of production experience, complemented by our dedicated international sales division. This integrated approach allows us to oversee every step from raw material sourcing to final export, producing and selling entirely through our own controlled channels.
Beyond our core formwork wedge pins, our extensive manufacturing portfolio includes expansion screws, specialized construction fasteners, precision hardware, plastic parts, stamped metal components, zinc die castings, and custom non-standard parts engineered to your specifications.
Our fastening solutions heavily cover the entire global construction sector and mechanical equipment installation fields. They are critical for structural formwork assembly, the secure installation of large-scale outdoor mechanical equipment, commercial home decoration, and heavy-duty fixed installation of goods.
Yes. We possess mature OEM capabilities and thoroughly understand the diverse standards of international markets. We can customize dimensions, materials, surface treatments, and provide bespoke logo printing to align perfectly with your project requirements.
Quality assurance is deeply embedded in our workflow. We conduct rigorous inspections following every single manufacturing process. For finished products, we execute 100% final testing—including ultimate tensile strength checks—in strict accordance with customers' specific requirements and international standards to ensure zero-defect delivery.
When we quote for you, we will confirm the most suitable way of transaction, offering flexible terms including FOB, CIF, and CNF based on your logistical preferences.
For mass production goods, the standard structure requires a 30% deposit prior to manufacturing, with the remaining 70% balance cleared against the copy of shipping documents. The most common transaction method is by T/T, though L/C arrangements are also fully acceptable and supported.
