• Zinc-plated alloy steel construction provides excellent corrosion resistance, extending service life in harsh industrial environments.
• Class 10.9 strength grade guarantees high load-bearing capacity and durability for demanding mechanical assemblies.
• Integrated flange design eliminates the need for separate washers, simplifying installation and distributing clamp load effectively.
• Hex drive with 3 mm drive size allows for secure tool engagement and efficient tightening in confined spaces.
• Partially threaded M5 x 0.8 mm coarse pitch offers optimal grip and easy alignment, speeding up assembly processes.
• Rockwell C32 hardness ensures high wear resistance, maintaining thread integrity through repeated use.

Professional Applications & Engineering Value

This M5 rounded head screw is engineered to address common industrial challenges such as vibration loosening and corrosion-induced degradation. The zinc-plated alloy steel material combined with a Class 10.9 strength rating makes it ideal for heavy machinery, automotive components, and structural frameworks where high tensile loads and environmental exposure are concerns. The flanged button head design provides a low-profile, secure fit that resists tampering and reduces stress concentration points. With its coarse thread pitch and partial threading, it ensures quick installation and reliable clamping force in metal-to-metal or composite assemblies, minimizing downtime and maintenance costs in industrial fastening applications.
