- Enhanced assembly efficiency with a thin 9mm profile, saving space and reducing overall assembly weight
- Reliable reverse-thread security provided by the left-hand metric thread, preventing loosening in counter-rotational systems
- Precise, secure fastening ensured by the Class 6H thread fit and fine 1.5mm pitch for vibration-resistant connections
- Broad industry compatibility through compliance with DIN 439B and ISO 4035 standards for guaranteed interchangeability
- Easy installation and removal with the standard 27mm external hex drive, compatible with common wrenches
- Safe for regulated industries as it is fully REACH and RoHS 3 compliant, meeting strict environmental and safety standards
Professional Applications & Engineering Value
This M18 thin hex nut is engineered to solve critical challenges in industrial assemblies requiring reverse-thread functionality. The brass material offers excellent corrosion resistance, making it ideal for plumbing, marine, and electrical applications where moisture and chemical exposure are concerns. Its left-hand metric thread is specifically designed for components that rotate counter-clockwise, preventing accidental loosening under normal operational torque. The fine 1.5mm thread pitch and Class 6H fit provide a tighter, more vibration-resistant connection than coarse threads, essential for precision machinery and automotive systems. Manufactured to DIN 439B and ISO 4035 standards, this nut ensures reliable performance and interchangeability in global supply chains, reducing downtime and maintenance costs.
Specification Summary & Compliance
This nut features an M18 x 1.5mm left-hand metric thread with a Class 6H thread fit per ISO standards, ensuring high dimensional accuracy. The external hex drive has a 27mm width and a 9mm height (thin profile) as defined by DIN 439B and ISO 4035 specifications. It is manufactured from leaded copper alloy (brass) and is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) under exemption 6(c).
