Professional Applications & Engineering Value

These M5 flat head screws deliver exceptional engineering value in industrial fastening applications where high tensile strength and surface-flush installation are critical. The zinc-plated alloy steel construction provides superior corrosion protection for machinery, automotive components, and structural assemblies exposed to harsh operating conditions. With Class 10.9 strength rating and Rockwell C32 hardness, these metric screws maintain integrity under extreme vibrational loads and dynamic stresses. The coarse thread 0.8mm pitch ensures rapid installation and secure holding power in various materials, while the fully threaded design maximizes pull-out resistance. The 3mm hex drive facilitates efficient torque application in confined spaces, making these DIN 7991 compliant fasteners ideal for production lines requiring repeatable, reliable performance.

Specification Summary & Compliance

This M5 x 0.8mm x 35mm flat head screw maintains precision Class 6g thread fit according to metric standards, ensuring consistent threading performance.
