Color classification
304 stainless steel GB5281 hexagonal plug shoulder step limit screws are precision-engineered industrial fasteners designed for high-precision positioning, limiting, and structural fastening applications. Compliant with the GB5281 national standard and available in metric sizes M2 to M12, these step shoulder screws feature a hexagonal plug design and rigid stepped construction, making them ideal for machinery assembly, precision equipment, mold manufacturing, and industrial fixtures that require fixed-position limiting and stable load-bearing.
 
Crafted from premium 304 stainless steel, these screws deliver excellent corrosion, rust, and oxidation resistance, suitable for use in indoor, outdoor, and mild corrosive industrial environments. The integrated shoulder step structure ensures accurate axial and radial positioning, eliminating component displacement during operation, while the hexagonal plug design enables secure installation and torque control with standard hex tools. Engineered for consistent dimensional accuracy and tight tolerances, they match standard metric specifications for seamless compatibility with existing industrial components and assemblies.
