Fastening Technology 50mm Series Q & A

+ What is the Fastening Technology 50 mm Series used for?
The 50 mm Series Fastening Technology is designed for quick, strong, and precise connections between aluminum extrusion profiles in the 50 mm system. It’s commonly used to build modular frames, machine bases, guards, and automated equipment structures. The system allows for flexible assembly without drilling or welding, making modifications and expansions fast and efficient.
 
+ How strong and reliable are the connections?
The fastening system provides exceptional strength and durability, comparable to welded joints when properly installed. Its high tensile and torsional resistance ensure stability even under heavy loads or continuous vibration. For most applications, one or two fasteners per joint are sufficient, but multiple connection points can be added to increase load capacity.
+ How easy is it to assemble or adjust components?
Assembly is straightforward — no special machining, drilling, or surface preparation is required. Components can be joined or repositioned using standard hand tools. The fasteners are designed to automatically align and lock into the extrusion slot, ensuring precise assembly and repeatable results. Adjustments or reconfigurations can be made at any time without damaging the profiles.
 
+ What accessories or options are available?
The 50 mm series includes a full range of compatible fastening components, such as connectors, joining plates, brackets, and T-nuts. Each is engineered for specific connection types — from fixed right-angle joints to adjustable pivots. Accessories are available in various materials and finishes to suit different environments, including corrosion-resistant and heavy-duty applications. The modular design allows all parts within the 50 mm series to work seamlessly together. 
 
 
+ What should I know before purchasing or specifying components?
When selecting fastening components, consider your load requirements, environment, and assembly method. Standard parts are typically in stock for quick delivery, while specialized items may require additional lead time. Each product is manufactured to precise tolerances and undergoes strict quality control. CAD models and installation instructions are available to simplify planning and ensure proper fit. Technical support is also available to assist with product selection and application guidance.
