- High hardness and wear resistance with Rockwell C32 hardness, maintaining thread integrity through repeated use.
- Broad compatibility and precise fit with Class 6g thread tolerance, facilitating interchangeability and reducing assembly errors.
- Compliance with international standards including ISO 7380, ensuring consistent quality and reliability for global engineering projects.
Professional Applications & Engineering Value
Engineered for demanding industrial environments, these M3 rounded head screws address critical challenges in machinery assembly, automotive components, and heavy-duty equipment. The Class 10.9 strength rating and zinc-plated alloy steel construction prevent fastener failure under high vibration and load, reducing maintenance downtime. The coarse thread pitch and fully threaded design enhance grip in soft materials and allow for quick installation, while the hex drive ensures torque resistance without stripping. Ideal for applications requiring high tensile strength and corrosion protection, these screws deliver long-term reliability in manufacturing, construction, and electronics, supported by adherence to ISO 7380 for dimensional accuracy.
Specification Summary & Compliance
This screw features precise M3 x 0.5 mm coarse threads with a Class 6g thread fit per ISO standards, ensuring accurate engagement. It complies with ISO 7380 for dimensional consistency, RoHS 3 (2015/863/EU) for hazardous substance restrictions, and REACH (EC 1907/2006) for chemical safety, guaranteeing environmental and regulatory adherence in industrial use.
