Professional Applications & Engineering Value
These M5 metric screws with internal-tooth lock washers deliver critical vibration resistance in industrial machinery, automotive assemblies, and electronic enclosures where constant motion threatens fastener integrity. The 18-8 stainless steel composition combined with passivated finish provides exceptional corrosion protection in humid or chemical-exposed environments, significantly extending maintenance intervals. The pan head design with Phillips drive offers optimal clamping force distribution while facilitating efficient installation in confined spaces. Engineered with Class 6g thread tolerance and coarse pitch threading, these fasteners ensure reliable engagement in both metallic and composite materials, solving common challenges of thread stripping and inconsistent clamping force in production environments.
Specification Summary & Compliance
This fully threaded metric screw features M5 x 0.8mm coarse threads with Class 6g tolerance for precision fit. Manufacturing complies with JIS B 1188-D specifications ensuring dimensional accuracy and performance consistency. The assembly meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming absence of restricted substances. The internal-tooth lock washer (10mm OD, 0.6mm thickness) maintains secure fastening while the Rockwell B70 hardness rating guarantees durability against wear and deformation.
