Professional Applications & Engineering Value
These M6 metric screws with internal-tooth lock washers provide critical vibration resistance in industrial machinery, automotive assemblies, and electrical enclosures where constant motion threatens fastener integrity. The zinc-plated steel construction offers durable corrosion protection while the Class 6g thread fit ensures precise mating with standard metric components. The combination of 60,000 psi tensile strength and fully threaded design creates reliable fastening in high-stress applications, while the Phillips No. 3 drive enables efficient installation with common tools. These rounded pan head screws are engineered to maintain clamping force in demanding environments where vibration-induced loosening compromises safety and performance.
Specification Summary & Compliance
Manufactured to ASME B18.13.1M standards with Class 6g thread fit precision and M6 x 1mm coarse thread specifications. The zinc-plated steel construction provides consistent performance while meeting RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements. The internal-tooth lock washer (12.14mm OD, 0.64mm thickness) ensures maintained tension under vibration, with 10mm length and fully threaded design for maximum holding capability.
