Professional Applications & Engineering Value
These M4 flat head screws deliver exceptional performance in corrosive or high-moisture industrial settings where fastener failure is not an option. The 316 stainless steel material combined with passivated finish provides superior protection against chemicals, saltwater, and industrial atmospheres, significantly extending service life in marine, chemical processing, and food industry applications. The undercut flat head profile ensures a flush surface finish while the Class 6g thread fit maintains precise tolerances for vibration-resistant assemblies. With full threading along the entire 6mm length, these metric hex drive screws offer maximum thread engagement for critical joints subject to dynamic loads or thermal cycling.
Specification Summary & Compliance
This fully threaded M4 x 0.7mm x 6mm screw features coarse thread spacing with Class 6g thread fit per metric standards, ensuring dimensional accuracy and interchangeability. The flat head maintains tight head diameter tolerance (-0.127 to 0.127 mm) for consistent counterbore fit. Manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements for hazardous substance restrictions.
