• Reliable coarse threading (M4 x 0.7mm) with Class 6g fit, enabling quick assembly and strong holding power in various materials.
• Consistent performance and durability backed by Rockwell C32 hardness, maintaining structural integrity over repeated use.
• Global compliance assurance meeting ISO 7380-2, RoHS 3, and REACH standards, ensuring safety and environmental responsibility.

Professional Applications & Engineering Value

This Class 10.9 flanged button head screw is engineered to address critical challenges in industrial assemblies where vibration resistance, space constraints, and corrosion are concerns. The black-oxide alloy steel construction provides a protective layer against moisture and chemicals, extending service life in automotive, machinery, and outdoor equipment. Its flanged design eliminates the need for separate washers, streamlining installation while distributing clamp load evenly to prevent surface indentation. With a fully threaded M4 coarse pitch and precise Class 6g thread fit, it ensures rapid, secure fastening in metals and composites, reducing assembly time and improving joint reliability. Ideal for high-stress applications, this metric screw delivers consistent performance where precision and durability are non-negotiable.
