Professional Applications & Engineering Value
These Class 10.9 metric button head screws deliver critical engineering solutions where high tensile strength and corrosion resistance are paramount. The blue-dyed zinc-plated alloy steel construction provides both visual identification and enhanced protection against environmental degradation, making them ideal for automotive assemblies, machinery enclosures, and electronic equipment where M4 coarse thread fasteners are specified. The fully threaded design ensures maximum load distribution across the entire fastener length, while the rounded button head profile eliminates sharp edges in applications requiring user safety and aesthetic considerations. With hex drive compatibility and precise ISO 7380 manufacturing standards, these screws offer reliable performance in automated assembly systems and maintenance operations.
Specification Summary & Compliance
Manufactured to exact ISO 7380 specifications with Class 6g thread fit tolerance for precision mating components. The metric coarse thread (M4 x 0.7mm) configuration ensures compatibility with standard industrial applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming restriction of hazardous substances. The Class 10.9 strength rating corresponds to minimum tensile strength of 140,000 psi with Rockwell C32 hardness, providing consistent mechanical performance across production batches.
