- Superior mechanical strength with 80,000 psi tensile strength and Rockwell B85 hardness to withstand high-stress applications
- Precise left-hand threading for specialized reverse-threading needs, preventing unintentional loosening in rotating assemblies
- Easy installation and removal with 2mm hex drive and rounded button head design, allowing secure tool engagement and reduced protrusion
- Reliable thread fit with Class 6g tolerance ensuring consistent engagement and vibration resistance in metric assemblies
- Full threading along the 12mm length for maximum grip and load distribution across the entire fastener
- Compliance with environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industries
Professional Applications & Engineering Value
This M3 left-hand threaded screw is engineered to address critical challenges in precision assemblies where standard right-hand threads may loosen under counter-clockwise motion. The 18-8 stainless steel material provides excellent corrosion resistance, making it suitable for automotive, aerospace, and marine applications exposed to moisture and chemicals. Its rounded button head and hex drive design facilitate quick installation in confined spaces while maintaining a low profile. The coarse thread pitch (0.5mm) and Class 6g thread fit ensure rapid assembly and reliable performance in high-vibration environments, reducing maintenance needs and downtime. Ideal for securing components in machinery, electronics, and equipment requiring reverse-threading safety.
Specification Summary & Compliance
This metric screw features M3 x 0.5mm coarse threads with Class 6g thread fit per ISO standards, ensuring dimensional accuracy and interchangeability. The fully threaded 12mm length and left-hand thread direction provide consistent fastening performance. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious and regulated industrial applications.
