Professional Applications & Engineering Value
Engineered for demanding industrial environments, these M10 hex flange screws combine high-tensile Class 10.9 steel with zinc yellow-chromate plating to address critical challenges in machinery assembly, structural frameworks, and heavy equipment manufacturing. The fully threaded design with coarse pitch spacing ensures maximum grip length and vibration resistance, while the integrated flange eliminates the need for separate washers, reducing assembly time and component count. Meeting DIN 6921 and ISO 898-1 specifications, these metric screws provide consistent performance in automotive, construction, and industrial machinery applications where corrosion resistance and 150,000 PSI tensile strength are paramount for operational safety and longevity.
Specification Summary & Compliance
This M10x1.5x20mm hex head screw features Class 6g thread fit tolerance with right-hand coarse threads and full threading along its 20 mm length. Manufactured in compliance with ISO 898-1 mechanical properties and DIN 6921 dimensional standards, ensuring precise interchangeability and performance consistency. The zinc yellow-chromate plating provides environmental protection while maintaining Rockwell C32 hardness and 150,000 PSI tensile strength as specified for Class 10.9 fasteners.
