Key Features & Benefits at a Glance
- Enhanced corrosion resistance with black-oxide steel coating, ideal for humid or demanding industrial environments
- Precise thread engagement with Class 6H thread fit ensuring reliable connections and reduced risk of cross-threading
- Easy installation and removal thanks to the external hex drive design, compatible with standard wrenches
- Full thread coverage along the 10 mm length for maximum grip strength and uniform load distribution
- Robust coarse threading (0.6 mm pitch) providing faster assembly and resistance to vibration loosening
- RoHS 3 compliance with exemption for lead as an alloying element, meeting strict environmental and safety standards
- Metric system compatibility (M3.5) ensuring seamless integration with global machinery and components
Professional Applications & Engineering Value
This M3.5x0.6 mm coupling nut in black-oxide steel is engineered to address common challenges in assembly and maintenance, such as thread wear and environmental degradation. The fully threaded, right-hand design with coarse pitch enables quick, secure joining of threaded rods or bolts in tight spaces, reducing installation time in production lines or machinery repair. Its external hex drive allows for high-torque application without slippage, while the Class 6H thread fit ensures consistent accuracy in metric systems, minimizing the risk of mechanical failure in automotive, electrical enclosures, and structural frameworks. The corrosion-resistant black-oxide finish extends service life, making it a reliable choice for both indoor and outdoor industrial fasteners.
Specification Summary & Compliance
This coupling nut features a Class 6H thread fit per ISO metric standards, with M3.5 size, 0.6 mm coarse pitch, and dimensions of 6 mm width by 10 mm length. It is manufactured from steel with a black-oxide surface treatment and is RoHS 3 (2015/863/EU) compliant under exemption 6(a)-I for lead as an alloying element, ensuring adherence to environmental regulations without compromising mechanical integrity.
