Metric M-size rods / studs — available in Messing (brass) and Kohlenstoffstahl (carbon steel) Key benefits Wide size choice: available in M2, M2.5, M3, M4, M5, M6, M8, M10, M12, M14, M16, M18, M20 to match common metric components and repairs. Material options for the right use: Messing (brass) offers good corrosion resistance and electrical conductivity; Kohlenstoffstahl (carbon steel) provides higher strength and durability. Simple sizing and compatibility: metric sizing makes it straightforward to select the right part for standard nuts, fittings and assemblies. Reliable fit: consistent diameters and lengths help ensure predictable assembly and replacement performance. Features and specifications Materials: Messing (brass) and Kohlenstoffstahl (carbon steel). Sizes available: M2, M2.5, M3, M4, M5, M6, M8, M10, M12, M14, M16, M18, M20. Example format: M2*250 — diameter 2 mm, length 250 mm (use this format to specify other sizes and lengths). Practical applications (examples) Electronics and instrumentation: use small sizes such as M2 and M2.5 for securing circuit boards, connectors, and small enclosures where brass is preferred for conductivity and corrosion resistance. Mechanical repair and fabrication: sizes M4–M12 in carbon steel are suitable for machinery maintenance, brackets, and structural fastenings requiring higher strength. Furniture and metalwork: larger sizes M14–M20 for heavy-duty assemblies, frames and fixtures where carbon steel provides load-bearing capacity. Buying and selection tips Choose Messing (brass) when you need corrosion resistance or electrical conductivity. Choose Kohlenstoffstahl (carbon steel) when strength and wear resistance are the priority. Use the example format (e.g., M2*250) to specify diameter and length when ordering replacements or custom lengths. If you need a specific size or length not listed, specify using the M<diameter>*<length> format (for example M2*250 for 2 mm diameter and 250 mm length).
