Professional Applications & Engineering Value
These M5 metric screws with internal-tooth lock washers are engineered to solve critical vibration-induced loosening problems in industrial equipment, machinery, and automotive assemblies. The zinc-plated steel construction combined with the internal-tooth lock washer creates a permanent vibration-resistant fastening system that maintains clamp force where standard fasteners fail. The coarse thread pitch and Class 6g tolerance ensure reliable engagement in both metallic and non-metallic materials, while the pan head design with Phillips drive provides optimal driving torque transmission and flush mounting capabilities. This combination of features makes these rounded head screws ideal for applications requiring repeated disassembly and reassembly without compromising fastener integrity.
Specification Summary & Compliance
This M5 x 0.8mm x 10mm screw features Class 6g thread fit according to metric standards with coarse thread spacing. Manufacturing complies with ASME B18.13.1M specifications for dimensional accuracy and performance. The product is fully RoHS 3 (2015/863/EU) compliant and meets REACH (EC 1907/2006) requirements for environmental and safety standards. The fully threaded design and precise Rockwell B73 hardness ensure consistent performance across industrial applications.
