Professional Applications & Engineering Value
These M5 metric screws with internal-tooth lock washers deliver critical vibration resistance in industrial machinery, automotive assemblies, and electrical enclosures where constant motion threatens fastener integrity. The 18-8 stainless steel construction combined with passivated finish provides exceptional corrosion protection in humid or chemical-exposed environments, significantly extending service life. The Class 6g thread fit ensures precise engagement with mating components while the coarse thread pitch facilitates quicker installation in production environments. The combination of 70,000 psi tensile strength and Rockwell B70 hardness makes these rounded head Phillips screws ideal for applications requiring both mechanical durability and reliable anti-loosening performance.
Specification Summary & Compliance
Manufactured to precise metric dimensions (M5 x 0.8mm pitch x 16mm length) with Class 6g thread tolerance ensuring compatibility with standard metric components. These fully threaded screws comply with ASME B18.13.1M mechanical specifications and feature RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance. The passivated finish on both screw and washer components meets industry standards for corrosion protection while maintaining dimensional accuracy.
