Professional Applications & Engineering Value
Engineered for precision assembly, these M3 metric screws with 0.5mm coarse pitch deliver exceptional performance in electronics, machinery, and automotive applications. The zinc-plated steel construction provides a durable barrier against oxidation and chemical exposure, while the fully threaded right-hand design ensures maximum holding power in thin materials and plastic housings. The narrow rounded cheese head offers a low-profile finish that minimizes protrusion without compromising on drive efficiency. With Rockwell B71 hardness and 60,000 psi tensile strength, these fasteners resist deformation under vibration and dynamic loads, reducing maintenance downtime and improving product longevity in industrial settings.
Specification Summary & Compliance
This M3 x 0.5mm x 4mm screw features Class 6g thread fit per ISO metric standards, ensuring precise dimensional accuracy and interchangeability. Manufacturing adheres to DIN 920 specifications for rounded head slotted screws, with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted hazardous substances. The flat tip design facilitates easy insertion, supporting efficient high-volume assembly operations.
