Key Features & Benefits at a Glance
- Superior corrosion resistance in harsh environments thanks to 316 stainless steel construction
- Secure left-hand thread locking for applications requiring reverse-threading to prevent loosening under counter-clockwise rotation
- Space-saving thin profile with 8mm height for use in confined assemblies without compromising strength
- Precise Class 6H thread fit ensuring reliable engagement and vibration resistance in fine-threaded applications
- Guaranteed dimensional consistency and interchangeability through compliance with DIN 439B and ISO 4035 standards
- Easy installation and removal with standard 24mm external hex drive compatible with common tools
- Environmental and safety compliance meeting RoHS 3 and REACH regulations for restricted substance control
Professional Applications & Engineering Value
This M16 left-hand thin hex nut delivers critical performance in specialized mechanical systems where standard right-hand threads are unsuitable. Engineered from 316 stainless steel, it provides exceptional resistance to chemicals, saltwater, and industrial atmospheres, making it ideal for marine equipment, chemical processing machinery, and food-grade applications. The fine 1.5mm pitch and Class 6H thread fit create superior clamping force and vibration resistance in high-stress assemblies, while the thin 8mm profile solves space constraints in compact designs. Its left-hand metric thread is essential for rotating components where reverse threading prevents accidental disassembly, ensuring operational safety in conveyors, mixers, and precision instruments.
Specification Summary & Compliance
This nut features M16x1.5mm left-hand metric fine threads with Class 6H thread fit tolerance per ISO standards. Manufacturing complies with DIN 439B and ISO 4035 specifications for thin hex nuts, ensuring dimensional accuracy with 24mm width and 8mm height. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing adherence to environmental and safety standards for hazardous substances.
